Filaments vastly differ in the temps they need

It looks to me that its slightly over extruding, and that its too hot.

Follow this video
Its essentially telling you to find a print thats a single wall, and then manually change the temp with Gcode after so many layers, and keep doing it till you have a huge range of temps. Youll physically see which temps look correct and which dont

Its me again (>>885563)
Why does my prints bases warp like this?
>>
>>886283
forgot that warping only happens on one side of the print
>>
>>886283
>>886284
how are you adhering to the bed? masking tape works nicely
>>
>>886283
Your first layer is shit. Lower your hotend for better adhesion, which will help with your warping if you're heating it properly.
>>
Is there any difference at all between masking (yellow) and painters (blue) tape?
>>
Ordering my first machine. I have a choice on nozzle sizes for the "Allmetal V6" hotend. Which size should I get?

0.2,3,4 or 0.5mm?
>>
>>886411
I think that most printers have 0.4mm nozzle. I have 0.5mm and I have found some objects on thingiverse with some details, that I can't print, because they are too small. So, if I were you, I would take 0.4mm.
With smaller sizes, you can make better details, but it takes longer to print. Also the nozzle size determines your maximum layer height. Layer height shouldn't be more than 80% of nozzle diameter. (with 0.2mm nozzle your max layer height is 0.16mm ) This also means that it takes longer to print.
I suggest you take 0.4mm, unless you plan to print very small details.
>>
>>886283
Read about how to level your bed. Use the method with a piece of paper. It works very well to get consistent results.
>>
>>886396
Masking tape might not come off as cleanly and probably won't last for as many prints (it'll rip and such when removing prints). That means more replacing and more glass cleaning.
>>

3m scotch blue tape works best

I want to pick up a kit since I have a small amount of disposable income right now.

The bufag guide gives this link for a kossel kit:

http://www.amazon.com/gp/product/B00WPFVVQK/ref=as_li_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B00WPFVVQK&linkCode=as2&tag=3dhu-20&linkId=M3VIR5Y2FRD6T7FS

I went ahead and looked at Aliexpress and I found this guy for about 250. It has aluminum rails, and if I'm correct, all the injection molded stuff I could print replacement parts for in case of a break.

http://www.aliexpress.com/item/Automatic-Desktop-3d-printer-large/32261046955.html?ws_ab_test=201556_10,201527_3_71_72_73_74_75,201560_9

Seems like no matter what I can only really afford a Chinese kit.

I also looked at some Prusa I3 kits that were made of acrylyc. But from what I understand, acrylic isn't all that great and I'll just end up replacing it later.

So my quesiton: are either of these okay for a first printer? Or should I just pick up the SunHokey Prusa and replace the body as I go? I'm not afraid to tinker with the fucker if that goes into the decision making process. I just don't have "tons" of disposable income while I'm in school.
>>
>>886739
Every printer needs tuned periodically, every roll of filament is different.

Just because your baseline calibration is marginally better, people starting from scratch have a much easier time getting great prints in the long run.

To talk shit about someone learning the ins and outs of printing while you just click a "high quality" setting is laughable
>>
>>886818
get the folgertech kit, its much better than any chink kit
>>
>>886818
I bought one of these about two months ago.

They are not worth it. I have yet to get it to work.

Get a Wanhao i3 instead. It's almost the same price and it comes pre-assembled and is metal construction.
>>
>>887437
The REV B folgertech kits are pretty good because they have tweaked everything to be improved.

>>887481
>They are not worth it. I have yet to get it to work.

Why not?
What problems have you had?
>>
>>886810
Just get some harbor freight ones, they are plenty accurate and repeatable for anything 3d printer related.
>>
How accurate would a GT2 belt be for the Z axis, still in the process of printing and modifying parts for my coreXY build, heard conflicting information about how accurate belts can be for raising and lowering the z stage.
>>
>>887551
Z-axis belt is not ideal for a Cartesian printer. The slack in the belt doesn't go well with the sub-millimeter movements despite gravity helping it out. Leadscrews are much preferred because of the higher rotation to height ratio.
>>
Have i3, want to replicate

What electronics vitamin set do I get? Everything on ebay/amazon/aliexpress looks chinese and sketchy. Or should I just go ahead and source part by part?
>>
>>887624
Go part by part. I just put a machine together off ebay and it was easy. They group many of the parts together.

If you want to go piecemeal look up:
ramps kit
heated bed kit
stepper motors
dc power supply
whatever framing and linear movement setup you decide upon

I personally used extrusions and makerslide for mine with threaded rods for the z axis. I'm building a gantry setup for my new printer.
>>
How do you get a sheet of PEI to lay flat? I didn't pay close enough attention to mine and it bows up in the middle. Any object larger than 5 inches had bed adhesion problems and it will warp. I don't have a heated build chamber so that's not really an option at the moment. I bought a thicker sheet of PEI (0.09) and it's also bowed.

I figured I will try to get it to adhere to a sheet of glass concave side up so the edges are pulled down to flatten it out. Is that a viable method?

Damn, so my prusa i3v still can't print parts on size. Outside dimensions are less than .005" oversize and a .25" hole comes out .025" undersized. I have a .5mm head and using slic3r manually have my widths set to .5mm and i'm printing at .2mm layers.

It's PLA 3mm (actually closer to 2.9)

I did just increase my x and y steps to split the difference a bit.
http://www.thingiverse.com/thing:264782
I just now printed this with zero infill and managed to cram them together. I'm still trying out some test parts but it looks like I've done what I can with the slicer and just need to very finely tune these steps.

Need a quick advice in sight from some one with experience.

Print quality, speed,..
1.75 PLA vs 3mm PLA filament Cons and Pluses for each one.
With hotend, extruder nozzle (0.4mm) being the same.
>>
>>888253
>It's PLA 3mm (actually closer to 2.9)
>I did just increase my x and y steps to split the difference a bit.
What? Why don't you just adjust your E stepps?
>>888495
-3mm has higher extrusion force. Means more likely to skipp stepps or grind filament. (con 3mm)
-3mm +- 0.1mm is better than 1.75mm +- 0.1mm (con 1.75mm).
-1 E-stepp on 3mm is more than 1 E-stepp on 1.75mm (con 3mm).
-3mm does better with bowden setups (con1.75mm but dependent on design).
>>
>>888527
I mean as an end result. If we use the same setup (same material PLA, the same printer ,,..). is there a difference in overall accuracy and surface finish?
>>
>>888530
Well the 2 acurracy things work against eachother. If the filament has the same precision in % and not in mm then 1.75mm is better because you need more E-stepps per volume resulting in higher E-resolution.
In short you won't notice a difference unless your 3mm filament drive fails.
>>
>>888495
1.75 is pretty much becoming standard
>>
>>888527
um, I have been? also you input the actual filament diameter into the slicer as well.

>>888579
I'm pretty sure 3mm and 1.75mm are equally common.
>>
>>888586
Sounded like you were trying to adjust for filament size by changing your xy-stepps.
>>
>>888586
>I'm pretty sure 3mm and 1.75mm are equally common.

The 3mm standard from when the home reprap community started was based on need. They were using standard rolls of plastic welding rod as filament. It wasnt by design, but by what they had available.

Around 2 years ago when cheap 1.75 home filament started showing up, people started changing over.

Are you really going to run a delta with 3mm filament?
Have you felt the 2 side by side in terms of stiffness?

Sure you can still buy 3mm stuff, but you cant deny that the community as a whole has gravitated towards 1.75 for a while now.
>>
>>888603
Oh and dont forgot the whole "2.85 vs 3mm" filament horse shit
"3mm" isnt even standardized anymore
>>
>>888598
na, I turned my e-steps down, and then increased the xy-steps to split the difference between oversized perimeters and undersized holes. I was finally able to fit two pieces together

now i'm printing this for a friend for a school thing. so far so good, but i feel the quality could still be better. guess i'll try out some .1mm layers when i get around to it

If your homing is correct, it has to be the mattercontrol deal.

Try and move it to the far side of the bed and see what happens

I haven't used MatterControl, but try looking for settings as to how the origin of the bed is set up in the program.

All the settings seem to be in order. I did realize that the object is probably too big for my bed, so I'm going to try printing it in 2 parts
>>
>>888639
Will it fit if printed at an angle?
>>
>>888639
It's running a little more smoothly now, but it's still closer to the edge than it should be.

What's some good software to use? MatterControl works pretty well for me except when it started giving me problems today.
>>
>>888640
Maybe, But I don't mind if it's in two pieces. I've got some craft glue and it's supposed to fit in a desktop drive bay so it's not going to move around very much.

Manufacturers differ in their plastics, just because someone arbitrarily decided based upon one printer and one heat setting doesnt mean its correct for everyone.

Every person should be fine tuning their temps, not just choosing one because they read it online.

Ive had cheap ebay PLA that ran best at 165C which is supposedly 15c lower than standard melting point.

Prined ABS in the summer. ~25 celsius in the room, temp set to 230. Printed normally.

In winter ~19 celsius in the room. Had to turn down the extruder stepper fineness by 2x and turn the heat up to 255. Now it wont stutter anymore when printing.
>>
>>890232
Not uncommon to have to retune stepper drivers/temps a little as ambient temperature varies. With ABS, any warp will also be more pronounced at lower ambient temperatures.

there are 5 connectors on the board and there are 5 motors. I assume each one has it own slot.

Invest in a ceramic screwdriver
If not you are going to short out your drivers when you tune them.

Then youll be buying a whole new set of electronics because this is a all in one board.

Perhaps. The main issue here is that it all comes down to calibration. A well tuned chinese clone can meet or exceed FDM commercial printers. The only difference is about an hour spent calibrating and a slightly wider tooling.
>>
>>890432
Yes. You will want to see if your PSU will handle it, though.
>>
>>890432
You were told before you bought the printer it will support two extruders
>>
>>890409
>So, both Z stepper motors connects to one connector on the board?
Yes. Why would you want to drive both z motors independently? That would cause flexing on the Y axis as it (rolls? ~beta angle changes). If you want auto bed leveling, just move the entire carriage up and down as it moves along X & Y axes.
>>
>>890439
I plan to use an 400W ATX psu later on

>>890442
I thought ppl could agree on that. IT doesn't matter any way.
So if both Z axis motors connect to one slot - driver, it means it will probably over heat quite a lot?


There was somebody else who ordered the printer. Did you get it yet?
>>
>>890443
I don't know. I have seen somewhere a board that had Z1 and Z2 labeled connectors. If you plug both in the same driver it means more power and more heating. We had a little discussion about that in previous thread, so I just wanted to know how it turned out to be.

Loss of extrusion on the support material so the model extruder didnt have anything to stick the filament to.

It was a very disappointing monday.

>>890445
>>890446
>So if both Z axis motors connect to one slot - driver, it means it will probably over heat quite a lot?

Z axis shouldnt heat up at all, if you have your current set correctly.

It makes a very small turns to both rods, then sits for a whole layer.
Then it makes another small turn, then sits.

There is no chance for it to actually heat up.

Your Y and X axis are both constantly moving for the whole print, so they will heat the drivers up substantially more than the Z will even running 2 steppers.

Just make sure to tune your stepper current well, and maybe blow a small fan on the board. If it didnt come heatsinks, it should be fine.
>>
>>890451
caveat, auto bed leveling does actually move your Z axis up and down throughout the print to compensate for an unlevel bed.

But youll still be fine

"other guy" who ordered the same machine here. Mine arrived Friday and just finished the wiring a few minutes ago. Was about to plug in the PSU when I realized they gave me a plug for DC. Also the gauge of this wire has me worried.

I paid extra for the auto-leveling and metal extruder expecting to get 2 extruders. It was only 1 and the auto-leveler is just an inductive proximity sensor I could have purchased for $4 and a printed piece to attach it that they give you the STL files for.

>>890446
Probably that was the case for that other particular board. However, it is also a possibility that the two z connectors you saw were for the endstops. The z axis, even at a ridiculous angle with autobed leveling, moves very slowly and doesn't take much torque.
it just seems like unneeded hardware to have a second driver where one can do the job.
>>890455
I have a very similar i3. If you have the thick aluminum plate, it may be in your best interests to adjust the current to your x axis and add a small fan to cool the axis stepper [moving the bed].

they call it ABS+
it melts at slightly over 280c and is supposed to be stronger than regular abs.

its expensive as fuck and we want to use something cheaper. i dont know what the support material is but it dissolves in a chemical bath and leaves the model intact.
also expensive.

i wish i could just run plain abs through it but i have a feeling it will just turn to carbon or catch fire or something. i would rather pay $40 a kg instead of $200 for 56.3 cuin which i assume is a kg. i also think the abs+ is 1.6 instead of 1.75mm.

Ink can usually be removed with the same thinner/liquid that ink is made of. So, if it is water based ink, you can remove it with water, If it is alcohol ink, you remove it with alcohol, For anything else: https://en.wikipedia.org/wiki/Paint_thinner
Check marker label for ingredients. I got some inject printer ink on my hands once, I cleaned it with isopropanol and nitro thinner. But this things are quite harsh to the skin.
For removing from clothes: The problem is that paint goes really deep in the fibres - capillary action or something. Soaking and rinsing in paint thinner could work, but you risk discolouration and fibre damage. First try soaking and washing in water with some heavy duty soap.
The other solution is to paint whole pants in that colour.

Back. I plugged it in, tested the motion of the steppers and worked great. Decided to heat it up to push some ABS through. At about 200C the extruder started smoking. Immediately unplugged it and it continued to smoke for several minutes afterwords. Is this oils from the factory burning off, or do I have a problem here?
>>
>>890528
Where exactly did it start smoking at?
The extruder and hotend are different parts.

Did the Hotend start smoking?
I could see there being some oil in there or something because they throw them together and let them sit

If your stepper is smoking, thats not a good thing obviously

Removed the stepper all together and pre-heated it again. With the stepper removed I could see smoke was clearly coming from the thermistor. It doesn't show up on camera but there's a few drops of what I assume is oil in those clear insulating tubes.

Also, knob for LCD was screwed on too tight. managed to find the hidden nut and readjusted it so it spins more freely now. All looking good so far.
>>
>>890573
If those insulating tubes are PTFE, it might be better not to inhale the smoke.

PTFE doesnt burn till like 280c, so if its reading correctly it wouldnt come close to burning

Also it is ok for nozzle to be this off the bed when touching end switch? (in both x and y axis)

I switched my Z polished rods for the X rods and it turned out perfect size. I don't know about those end stops. With end stops only on 1 side I don't know what purpose they'll serve. Maybe calibration?

The leveling sensor needs to be 2mm above the nozzle but you don't want the nozzle touching the bed. You should be able to slide a piece of paper under it with a little bit of drag but no tearing. The M8 wrench they gave me is 1.82mm thick. Combined with a blank piece of paper it's 1.99mm.

Cant find out what is + and what is -.
>>
>>890989
there's full instructions in the SD card. Not organized tho. I'd say pre-heat it and manually push some plastic through. Then configure Cura with the setting provided, generate some, gcode and do a test print. I recommend downloading the newest version of Cura from their webpage, the version they provide is out of date.

Right now I'm trying to do a test print but nothing is sticking to my heat bed.

>>890989
Heating elements aren't polarized.

You connect your board to your computer with a USB cable and install drivers if necessary. Find a test cube stl and use a slicer to get your gcode. Send it to your printer using your host to upload or stream the gcode. Depending on which host you have, you might need to set your baud rate and com port.

I don't know for Cura, but Slic3er has a setting for Z Offset. This setting is then used in g-code. So, check your settings and you can also check g-code.
There might be an option to set offset in firmware. In Repetier it is called: #define Z_MIN_POS 0. (I have never changed that, so I am not sure how it works, as far as I understand it is meant for setting offset).

Did you calibrate nozzle height when it was cold or hot? Your problem might be thermal expansion?
>>
>>891788
currently everything is set like this when I home.
x (-15) (0 is at the left edge of the build plate)
y (-45) (0 is at front plate of the print bed)
z ( 0 ) the paper goes under the nozzle
Is this ok.
There is a z offset setting at it set 0.5 by default.
It could be that I had some setting wrong in Cura when making G code?

Where is this set? On printer or on some program on computer (Cura, Repetier-Host)?

Can you change that? If you set it to zero does it lift up or down?


You can open g-code with notepad or Repetier-Host. Find first G1 Zxxxx value and compare with height that you set for first layer.

ok me again
Did this first print yesterday and got a massive block somewhere in the middle of the heatbreak. I clean it today and also isolated the hot end so there is less heat going up to heat break.
I don't know the exact setup but the temperatures were around 205°C hotend 45°C heat bed room temperature was around 20 °C
Print speed was around 30mm/s, layer height was 0.2, flow as at 170% (this probably needs calibration if it is off by this much?) Nozzle is 0.3 mm


So can someone give a quick run down on what setting should I use to print this 12 x 12 mm cube? Printing PLA

Yes. It didnt come with a hard drive.
Stratasys makes people destroy the hard drive when they end their use of the printer. Something like that at least. Also these printers are 10 years old. Some work some dont. We pulled the hard drive and control boards from one of our working printers that was in bad shape and transplanted them into that printer to make it work. Its probably the most in-calibration printer we have now too. The old printer that donated parts is now the parts machine instead.

I think he has this: https://www.3dprintersonlinestore.com/electron-3d-prusa-i3-kit

He has direct drive, while you have geared drive, so his steps/mm value should be much smaller.

Hey all.

My X-belt on my Prusa i3 are buzzing whenever it moves to do infill (at a higher speed).

Do they need to be tightened or what?
>>
>>892669
more often I find that buzzing comes from rubbing. whenever mine start to buzz i check to make sure it's not rubbing one side of the pulley/idler. may not be the case for you but something to check
>>

looks like some serious control boards in there
Cool that you got it running switching shit around

>>892578
You should check the bed level every time you use it.

>>892669
Does it have enough current?

>>892658
Check that the gears don't have ground filament in the teeth. Mind your current. Calibrate your z axis. Does the cold end ever kick or jerk?

IT appear that the extruder is grinding the filament. So either the nozzle is to small (for the selected printing speed (20mm/s), or the idler is not making enough pressure on the filament.
>>
question for the other guy who ordered the same elektron prusa i3.
How are our prints?
Did you have any similar problems?
Did you have to calibrate (other than bed)?
Did you change FW much?
>>
checked the extruder.
When ordered to extrude 40mm it actually extruded 38mm.
But could this cause so much under extrusion as seen on the pictures above?
>>
>>892946
>>892947
>>892953
Are you the same person?

>>892946
Some causes for grinding filament:
1.- Not enough force on idler
2.- too much force on idler (I read about that somewhere, I am not sure if it is true)
3.- clog in the nozzle
4.- Temperature too low
5.- Bad cold end/heat break (I had this problem: It was printing fine for 30 to 40 minutes, then it started under extruding and then it stopped extruding, while drive gear was grinding the filament. It is sort of ceramic hot end, so it didn't have a fan like metal hot ends. I solved it with adding a fan on cold end. )

What I would do: First clean drive wheel and idler of plastic shavings. Assemble back together. Disable the stepper motors (In Repetier Host: round icon with crossed motor ). Heat the hot end to desired temp., when it heats up, push filament with your hand. It should go quite easily and the motor should spin. If this works, you can eliminate cause 3 and 4.
-Force on idler: probably with trying.
- Bad cold end /heat break: Touch the cold end with your finger while printing (be careful - do not get hurt by any moving parts, don't touch the hot end). Glass transition temperature is for PLA 60°C, so the cold end should be much cooler than that.

>>892953
This is not very bad. That is Flow setting 105% in Cura or Extrusion multiplier 1.05 in Slic3r

yup same person.
I did adjusted the extruder speed to 105,.....
Well will probably have less problems when 0.4 nozzle arrives. currently using 0.3.
This Chinese one is of poor quality. Even the hole is not in the middle

HMm adjust the extruder to 105,...Run a test request 60mm of filament , 63mm of filament comes out. Re run the calculation. get 94,.... Set 94,... in FW. Run a test again request 60mm of filament , 56.5mm of filament comes out. Now I set it to 100 to see how much it comes out.
>>
>>892980
Its very important to not over tighten the idler on your extruder

You want it barely leaving marks in your filament. Not deep cutting no deforming.
Just tight enough it wont slip.

So the latest print.

Need to use brim because I have some problems with print coming of bed later in the print. Even the with the brim the part came off partly. The bed was at 26 C. Probably need to heat it up later in the print to prevent the print to came off.
The bottom (1.2 mm) was printed at 5 mm/s at 220 C
The middle part was printed at 10mm/s and the top (last 5mm) part was printed at 6mm and temperature of 230 and flow at 130 I think.
Better then previous prints but still far from good. Under extrusion seem to be the problem

Also the dimensions are around 15.03 for x and y axis and 14.6 for z axis (probably due to print coming off on one side mid print )
>>
>>892980
Don't forget: inconsistent filament diameter. I've had issues before. Mic'ed last half of a bad roll every 12 inches. Spec'ed at 1.75mm, found areas as big as 1.9mm.
>>
>>893081
Why are you fucking with flow settings?

Adjust your extruder Esteps, flow is only for very fine tuning.
https://www.youtube.com/watch?v=w_Wb0i0-Qvo

Make sure you are not over tightening your idler
It will grind, it will deform making uneven extrusions, it will cause undue pressure on your stepper which can cause missed steps


And if both of those are ok, make sure your nozzle isnt clogged with something. Heat it up 20C higher than you usually would and then just hand feed filament hard to hopefully clear a small clog. If not it takes disassembly of the hotend.
>>
>>893153
If it cuts any deeper than this (and IMO this is on the deep side, especially fir 1.75) then you are deforming for filament causing variations in the size when it hits the hotend.

Look for M106 Sxxx (fan on, with speed xxx)

So I'm trying to start a small online business selling 3D printed products.

What printer do you believe would be best for me to use? I have $1,500 to start this business up. I know its unrealistic, but I'll use an easy website builder, buy some ads here and there, and print orders as they come while offering free shipping. The product market is aimed towards stoners, degenerates, and edge lords.

I'm a poor fag and I'm hoping to make the most of this money before my Bipolar gets the best of me and makes me blow it all on drugs. I'll be moving across a state soon to NY if that helps, living with five other people in a one bedroom apartment. I mention this because of potential printer noise/ventilation requirements. So far, I'm interested in using PLA as Acetone Vapor Treated ABS isn't the best right now.

If you epoxy it, you want be able to replace it very easily if it fucks up later. Try dry fitting it with the middle screw hole instead. As long as it hits the switch at the same point along the axis, it doesn't really matter if you have it mounted a half an inch off. You could also drill new holes in the frame to use the other screwholes instead.

I put together a Tantillus 3d printer, but I'm having this issue with horizontal banding, and I'm not sure what's wrong.

the same problem occurs on parts that aren't thin walled. It just under-extrudes some layers or something. Is this maybe a temperature control issue with the extruder? Or maybe I'm trying to print too fast?

I don't think it's an issue with the z-axis moving uneven amounts, I got a ballscrew on the motherfucker.
>>
>>893587
What software are you using to run it? Some programs have sliders for extrusion/print speed adjustment.
>>
>>893598

I'm using Slic3r and Repetier host. There's a slider for speed, I can try slowing it down.

The XY axes can go pretty blazingly fast, but maybe the bowden extruder with a small nozzle can't lay down the plastic enough. though It seems to do fine most of the layers, I don't know.

>>893598

So I slowed it down to a painful 50% speed, but it did not seem to help. the full speed print is sitting on the right.

Speed does not seem to be the problem.

belts not tensioned properly, maybe printer moves on the table too

It doesn't seem to be a mechanical problem. I switched to Cura engine, and that seems to have fixed that problem. now it's just putting down too much plastic and the corners are staying molten and curling up. Not too much mystery to that, though.

check your z rod/screw/belt.
It seems to be off because it is moving more than it should.

Hi everyone I'm trying to start a site/business where I sell 3D printed stuff for a very low cost to potential customers. I'm hoping by doing this I will improve my ability to cater to specific niches and better understand the kind of stuff people might want to be made for them using a 3D printer like the one I have. Basically I just want to get a taste of what it's like to run a business and have that responsibility. Can anyone here critique my site and tell me what more you might want from it so I can add it in? One thing I plan to do is make a price calculator and a built in 3d model upload function, but for now all negotiations are available through e-mail which I have access to 24/7. I don't expect to become rich off this but I simply like the idea of having a 3D printing business because of all the possibilities it presents. As of right now I haven't spent a ton of time marketing the site so I haven't sold anything, but I have made a lot of things for friends including War Hammer 40K figurines and the like.

Thank you so much for responding. My machine is a cheaper model at around 900$ called the Da Vinci AIO by XYZ printing, but it has a scanning function as well. I'm aware that it has some negative reviews but it's mostly because people using it are inexperienced and just getting into 3D printing and expect it to work perfectly right away. I'm willing to acetone treat and paint models for people if they want it done, I almost feel compelled to do it if it's an art related request or a figurine. How would I get attention/business from bigger companies so I can make bulk models for them? I'm thinking some kind of ad-campaign would be good.

I'd like to see some quality samples.

Looks like you have two sides here, printing and modeling. Seems like the printing space is filling with competition quick, a handful of staples stores will print though i haven't seen one.
The modeling also has me intrigued but doubtful. If you're modeling a technical piece, either someone already has blueprints and then you just have a matter of translating that into a 3d model for them. If it's not a technical part then you're getting into artistry which would be touch to scale with a business. And i doubt scanning parts and printing them it's as easy as it sounds and doubt it'll keep up quality.

So why the Da Vinci? Those turnkey solutions are proprietary and I believe most of them require you to buy their own "filament cartridges" as well. Unless you plan on using them for support to the fullest extent, I'd never build my business to run on top of someone else's if I had the choice.
>>
>>893638
>>893759
what were your temps getting down to? after much trouble shooting I finally noticed a "cold extrude prevented" error message cause my i3v was getting down to 170C and would stop extruding but carry on the other motions. It took me forever to notice and that looks exactly what's going on.

Yeah obviously at the time I was not thinking this far ahead, I didn't plan to use it for a business which is why I'm looking into investing in a lulzbot, but it can still be used for the scanning function which for me was the selling point, I also have the new kinect hooked up to my PC that does more free form scans if that matters at all, it can be used to scan people and body parts. Lulzbot is also multi-material which is bretty gud. Pretty much any multi-material printer is on my watch list for purchase at this point. That and I'm somewhat interested in the ghost gunner and similar devices. I know that competing with pre-existing organizations is very hard but it can't be utterly impossible especially if I am more flexible about pricing and other variables but who knows.
>>
>>893894
Also I can hack the machine itself to use other types of filament but whatever. The "modeling" aspect isn't what I was considering a service so much as the literal act of printing an object, making it look nice and shipping it in my case the same way staples does in store as you yourself mentioned except they don't go as far as I would go to please the customer. Staples basically let's you use a 3D printer like they let you use a fax machine LOL. It's kinda like saying I just slaughtered a sheep and I have no idea how to turn it into food/clothing guess I have to take it to someone who can make use of this for me. Well someone can have access to and download like 70GB worth of 3D models but if they don't have access to a 3D printer they can't really do jack shit to make them a physical object now can they? Save for sculpting it from clay or something, but why do that when they can pay like 3-8$ for a complicated figure from a video game that normally costs like $50 if they buy it from an online specialty store or a hobby shop.

>>893880
There's a setting in your firmware for minimum extrusion temperature below which it will stop power to the extruder stepper to prevent cold extrusion. Find it and change it.

The guy with problems printing here again.
I have a question about z axis moving. On my i3 I can't manually move z axis in steps. Smaller than 0.1 mm. So if I set layer hight in slicer to something like 0.13 or 0.17 will printer z axis actually move by that much or will it approximate to 0.1 or 0.2?

ok found this article.
It literary states each problem I have and what is causing it. I recommend reading if any one have problems with small nozzles (0.3 or smaller ) or want to try to print with small nozzles.

I just slowed my printer down. It has no problem keeping its temps up, but just seems like it's slow to react to checking its temps and warming it up as needed.

If you don't have "name" and reputation for being able to deliver small batchs of good quality parts with 0.01 mm tolerances then it is quite pointless to hop into it at this point unless your city doesn't have a printing service yet. Mostly the parts we make are housings for electronics and prototypes. Cheap scanners suck so badly that they're basically useless. If you want to make money you have to look for other 3d printing technologies that produce better quality with complex shapes.

I meant other technologies than FDM (or FFF). FDM has its place for certain things but lets be honest, it sucks. There is no need to buy a expensive Stratasys printer when you can build almost as good machine for around 800€ (or 3-10k€ if you want a prebuilt).
>>
>>894129
I think the only way these hobby printers can be a business is when it's paired up with existing machine shops (or mechanical skilled people) that can then refine parts even further. I've made a prosthetic hand and reamed out the holes to press fit dowel pins. So I see FDM as just a step in the overall process.

I haven't had much time to work on it. I've had all sorts of problems but by some minor miracle I managed to print 3/4th of a test cube. It came out pretty good. I was impressed. (sorry for camera phone quality pic) Now if I can get it to work 100% of the time.

Still having adhesion problems even with painters tape and PLA. Filament tends to curl when it comes out the nozzle looping back hitting the nozzle, causing a big goopy noodley mess on 1st layer. Turning on auto-calibration causes it to print too low. I got scratches on my aluminum plate in the shape of 1st layer of print now. Can't get drivers to work so been printing off SD card. SD card only registers 30% of the time so need to keep reinserting it. Sometimes right threaded Z rod becomes frozen, throwing them both out of alignment. I suspect bad bearing on polished rod. With so many setbacks I was getting really discouraged. Glad I finally got something to print.

Almost any 3D program can do that. Since you're just starting out grab something free like Autodesk 123D if you're more interested in a CAD like environment, or Blender for something that's a little more free-form.
They both have their learning curves but for something like that tote I imagine it'll mostly involve posting your scan as reference and either edge or box modeling from there to get the basic shape. After that it's just a matter of pushing and pulling vertices, adding the occasional edge loop, and probably messing with chamfers, until you get the exact shape you want. Shouldn't be too difficult.

What do you mean with that - manually? Does that happen when you turn threaded rod by hand? or when you are setting height with that button on 3D printer? or when you are setting height with software on computer (Repetier-Host or similar )?
In general: For stepper motor with step angle 1.8°, 16 microstepping and Acme screw: you get 2015.75 steps/mm. Calculate for yourself: http://prusaprinters.org/calculator/
So, this should get you a resolution of 0.0005 mm/step

Manually I mean with the button or in the slicer. So in the auto mode (when printer is printing) it can actually move z axis in steps smaller than 0.1

it actually print like that
>>
>>894652
is this problem only with inventor, because other programs scale fine.
>>
>>894653
well thats odd.
>>
>>894654
It also happens with .dae files exported from sketchup

ok fixed it
There is a option menu when you save as and export to stl. Where you can change resolution
>>
>>894666
>not making it fixed to super high resolution all the time.
>dope_smoking_programmers.tiff
why is that option even there?
>>
I slice with Cura and print with Pronterface.
>>
>>894642
well it's not exactly a plugin, but maybe if you install pronterface or python it'll just show up.

>>894647
for inventor, when you export, after changing the filetype to stl, click the options button and change it to millimeter.
>>
>>894669
There was a time when the file size was important. Even today you might run into problems while transferring huge files.

So if i want to build my self a 3d printer ( not a kit) what board would you recommend.
I see the whole ramps 1.4 kit (with LCD mega board included) go for $30 eBay. Is this a good buy? Are there other boards that offer better value.
Also are this boards reusable for quad copters or other fun projects.
>>
>>894954
RAMPS is like a sheild for the ardunio, so no, that's geared for 3d printing. The ardunio mega you pair with it can be used however you want though
>>
>>894959
That what though. Since mega and ramps boards are separated you can use mega board for other things or upgrade other things. Which isn't. An option if both boards are merged in one board like with some other printers.

If holes come out to small an outer dimensions to big should I lower the feed rate? Printing PLA with 0.4 nozzle and 0.2 layer night. A 20mm hole is about 0.05 to 0.1mm to small and outer size is about the same to big
>>
>>894990
Adjust the scale and reslice, not the feed rate IMO.
>>
>>894997
What scale? You mean re calibrate x and y axis?
>>
>>895001
I kind of have an idea what hes saying. Its not about scale though. You arent accounting for ooze. When it lays down the layer it has a little bit of squish out to the sides. Slowing the feed rate slightly will lay a slightly smaller line of plastic. Or adjust for it in your design program by making insides of holes .01 mm larger and the outsides of objects slightly smaller too.
>>
>>895044
I think you're right. Another option is to scale it so the outer dimensions are correct and drill the holes out.
>>

I got the stl file of this LM8UU linear bearing from the thingiverse so I can't change the actual medel in inventor. the problem is the bed the bed where the bearing is.
here is the bearing holder

If I scale it in slicer the centers of the holes won't be on the same place any more.

>>895044
that is what I was thinking.

Hmm why is there such a difference in temperature between nozzle and bed. The printer has been off for 20h.
>>
>>894990
I've was fighting this problem for a while. What you need to do is fine tune your steps.
In short, you probably need to reduce your E steps and increase your X and Y steps
take a look at this. you print a model at 95% infill and adjust your steps on the fly till you have fine lines in the infill

I agree that reaming out holes will be the most accurate, but I was getting holes .015" undersized (actually .1mm is about .003", that's probably as close as you can expect to print, try making a fitted parts test print)
>>
>>895075
that is what I'm doing now. I'm printing a 20mm high cube. First 10mm will be with 100% feed. The last 10mm will be with 94% feed.
>>
>>895083
Ok test print done. The bottom 10mm was done at 100% feed rate and the outer dimensions are 20.13 +- 0.01
The top part of the cube was done at 94% feed rate and the outer dimensions are 20.02 +-0.02
The walls are about 1.65 +0.02 (target was 1.6)
Also the outer dimensions are off because of corners. If I measure the width in the middle, it is pretty much on target.

bump limit?

yup
we need a new thread

was it in the sunlight? aluminum plate with large surface area could heat up slightly in the sun
