Been trying to print PETG for past couple days. What a PITA. Took hrs of trail n error just to get it to stick to BuildTak surface Tried various temps from 235-255 bed temps from 40-80. Using a modified PLA profile in Simplify3D, 255/80 slowed down 1st layer speed to 30% .2 height. Bed leveled with .1mm distance. Adhesion worked the first print but the bottom side is horrible.

Well unfortunately about hr 3 the extruder must have clogged Finally got to change over to the SS nozzles I got and then proceeded to have another 4 hrs of issues with the first layer not sticking ugh!!! Finally just peeled off the relatively new PEI sheet and put on a new one Do PEI sheet got to crap that quickly? Less than a week? Maybe it's the quality of the sheet?by RC-CnC - Printing
SREK All I print is ABS I'm design can easily be adapted into a cube style printer, I just need to buy more extrusion I currently 2hrs into a 6hr print and I have the printer draped with a wool blanket atm, and of course it is attended. I'll post some results laterby RC-CnC - Printing
I have excellent results with lower profile prints, but Im trying to print a PSU cover and about 2/3 the way a layer starts to delaminate. Not completely but it looked different to me and I was able to completely break it at that point. 230/105 25% infill no cooling fan. Print is 115mmx30mmx75mm, 3mm bottom 2mm sides Thought maybe it was cooling off too fast, so my second attempt I covered theby RC-CnC - Printing
After searching most of the day. Is thisTR8x2 Delrin Nut the only place in the world that sells these? Does anybody have a source in the US?by RC-CnC - General
Thank you That's what I was thinking just wanted to make sureby RC-CnC - Printing
Building a Cartesian style printer single Z stepper and dual TR8*8 screws Would there be 2 calculations involved here or since the stepper and both screws are 30T pulleys would I just calculate for the screws?by RC-CnC - Printing
I replaced the kapton tape today and bought some acetone. Re leveled the bed .1mm in each corner and slowed down the first layer speed. Seems to be working but still not as good as beforeby RC-CnC - Printing

I apologize guys I was away for awhile It is a Cartesian machine dual z axis/attached TR8*8 screws Nema 17 84 ozin Marlin 1.0.1 I know its an old version, but it's the only I could get to run on the Azteeg X1by RC-CnC - Printing
Been printing a couple weeks with ABS and kapton tape 240/110 deg. Prints have been perfect. Turned on the printer tonight first layer wont stick. Releveled to .2mm and .1 mm No Cleaned surface No Changed kapton tape No Tried lowering temp settings No Nothing I do seems to make a differenceby RC-CnC - Printing
Custom built printer. You are correct...I forgot to add in the original post I'm doing only 1/8 steppingby RC-CnC - Printing
Hey fellow melters I have excellent quality prints except as the Z increases the print gets a bit larger, not askew and it's not that much. x-y calibration issue? Using GT2 belting .2 pitch with 20T pulley, but my calculation I get 40by RC-CnC - Printing
Yeah It's the only version I can get to work with the old X1 hardware. Is that in the config file?by RC-CnC - Firmware - Marlin
Chris This must not be in Marlin version 1.0.1by RC-CnC - Firmware - Marlin
Hey folks Finally got my printer assembled and wired. I had an Azteeg X1 3D Printer Controller v2.0 loaded with A4988's and a VIKI display so that's what I used Anyhow I was wondering if I missed anything in the config file. The steppers seem like they just go to sleep after 20 sec or so. Any help or advice would be greatly appreciated. // Disables axis when it's not being used. #define DISAby RC-CnC - Firmware - Marlin

Upgrade from the Igus plastic bearings which have a higher friction coefficient than the 2 V-slot extrusions and wheels in photo 2. Next will be a MIC 6 1/4" plate with 200cm sq heating plate from Panucatt. By my calculations it should reduce overall weight of the carriage.by RC-CnC - General

Quotecdru QuoteRC-CnC Z axis with belts is going to require to level the Z axis every time you power up the machine also when you remove power to the steppers the z axis can fall from the weight. I'd rather not mix belt and acme rod, just my preference.While it's fine to have a preference, why do you have that preference? Just aesthetics of having them all match?

Well I'm sure as time progresses you'll see the need...I'm just cutting edge I like new technology...As more boards are used you'll see profits go up...as with any new technology. Remember how much $$ top loading VCR's started out in the early 80's Now if the Mach 3 designers would get off their duff and change over to USB...Parallel really c'monby RC-CnC - General
It just seems like Smoothie is easier to configure. Hell if you want complicated and unstable buy a Microsoft product... I'm all for more efficient and easier designs.by RC-CnC - General
QuoteRalph.Hilton I think any engineer who knows their stuff does that too :-) I would ask as the first question - what do you want to make with the printer? You don't need great expense to get zero Z wobble so there is a sweet spot between healthy over-engineering and overkill. Absolutely... I also look at the ease of calibration on all axes. Upfront cost on mechanical components are not atby RC-CnC - General
I have a tendency to over engineer machines But my stuff lasts and is accurate.by RC-CnC - General
I've been debating on what to use on my build. Z axis with acme screws is going to be easier to keep level. Z axis with belts is going to require to level the Z axis every time you power up the machine also when you remove power to the steppers the z axis can fall from the weight. I'd rather not mix belt and acme rod, just my preference. I suppose I could design to be entirely acme screw drivenby RC-CnC - General
