I have 60 files i am updating time to time and slicing takes a lot of time. I thought to get on the console and try to automate it but i ran into some problems. My designs are made in Inventor. Its a battery enclosures and those are made up of 6 components. those components then are assembled and exported to stl. i can automate this process in Inventor so it save a lot of time.

Glass transition of PETG is 80-85C. I would say that 70-75C is optimumby agniusm - Prusa i3 and variants
I want to put all my mods in one place. I am panning on building a 12 printer cluster and P&P robot later. I had to modify Ender 3 to my needs as i dont like bowden and it seems to be a great platform for little money. Here is the list of mods i will be making: 1. Duet wifi 2. 5V induction probe 3. Microswitch filament sensor 4. E3D V6 5. Titan extruder 6. DB15/2 extruder assembly breakout 7by agniusm - Prusa i3 and variants
Quotedc42 Did it print the two perimeters in the same direction, or in opposite directions? Wasn't paying attention, think opposite. Whats weird is s3d was generating files over MB when slic3r 300kbby agniusm - General
Quotedc42 Which slicer did you use? Some slicers produce much more consistent gcode for circles than others. OK, Went back to slic3r and the problem is gone. Weird, never would think it might have to do with slicer. It also stutters printing skirt in s3d and i read about it on duet forum. Really weird. So much work cause of 150USD slicer ? Really glad i know where the problem lies as i was startby agniusm - General
This is a shot where i spaced out right side by 3mm: Also changed Y steps from 80.22 to 85 and circle came out oval with the same yin yang artifact (could i have just came up with the name for 3D printing error? )by agniusm - General
I use Simplify3D or slicerby agniusm - General
Printed 9 circles around the bed to see if the belts where to blame but they have same artifact all over. I have made a video to show the problem. Running our of idea here. I have set my XY steps to 80 (X80.06 Y80.22 before) and that did not do anything. You can see it has that bulge diagonally. I will try to disable pressure advance now P.S. Disabling pressure advance - no effect Alby agniusm - General
OK, something weird. The squareness of the axes does not have dramatic impact on the print. I have spaced out right side by 1mm and printed a circle, then paused a print and transferred 1mm spacing to the left side and resumed to print second circle and they looked same, same problem in the same place.by agniusm - General
Nothing noticeable but i will look and see if it does.by agniusm - General
The thing that bothers me that its not related to certain axis. Its more diagonal to XY axes and that is probably why i had hard time calibrating X and Y steps. I would change one axis and the other goes out of tune. One hint is that printing a tube does not make it oval, it probably is slightly oval, but the wall thickness goes from thin to thick, like in/yan diagonally so its not tied to cerainby agniusm - General
Thanks David. So basically my round objects being not round is more of a belt being not parallel rather then skew of the XY as i did print XYZ skew compensation sample and did offset it but it made little difference?by agniusm - General
Thank you. Sorry i have not responded sooner. Kids I might have a slight misalignment. I reused creality CR10 pulley and it is larger than the one on the motor side. I have teethed one so i might swap it. Y axis i think is better. Here are some photos of the beltsby agniusm - General
Ok. Got it connected. I have red light and when i tap the nozzle blue one comes up. Does that pot controlls sensitivity? I might have a problem with my system and need clarification. My extruder is pulled on a bracket and not the bearing itself which will trigger piezo while traveling on x. How the probe is engaged? If it will stop at designated spot and then engage it wont be a problem as x woulby agniusm - General
Not asking wire to wire wiring but rather where to connect, to z probe (4 pin) or z stop (3 pin)? Got it. MOD, so its z probe connector. Thanksby agniusm - General
Understood. All is good, just confusion. The pins are marked so i assumed marking are wrong . Regarding shipping, I post stuff to US and its there in 10 days and thats cheapest option from postal service. It probably how RM works. I remember same when living in UK. Is there a guide for wiring to duet? I found firmware setup and kind off remember somewhere written to wire to Z endstop but not surby agniusm - General
So i finally got the pcb (took 2 weeks in EU, royal mail is as bad as it gets). Stickers all over, pin out changed, check wiring. PCB 1.1 looks nothing like on the website. There is only one adjustment screw. Website does not contain info on this or pinout and i am left stranded guessing if the pinout markings are wrong or something else.by agniusm - General
I will insulate it with kapton. I cant print the bracket as my bed would not reach then and i will loose some. Probably not the major but still.. I wander if i could make couple of washers out of something to allow for some movement between my bracket and rail blockby agniusm - General
Hi. I have asked this on the duet forum but thought i migt want some feedback from the users. Ordered pcb with 20 and 27mm discs. My setup is rigid with no printed parts that hold the extruder. I have totan aeto. Couple of photos: Which way would you suggest mounting it? I could mill the aluminium bracket I have to accomodate piezo but dont know how deep as i was told thicknesses varies.by agniusm - General
You See, i cant grasp around this concept. motor pulley is teethed and that angle does not do anything in my opinion. I have slight bend on the belt but the artifact is across all 5 samples. I have checked and my beds edge is not perpendicular to x gantry. i am not sure if its only the med or motion system as well. That would definitely have so impact of axis being skewed, I am checking if i caby agniusm - General
Thanks. But can you notice diagonal lines on the 3rd photo? i have another problem which might relate. When i print round object, circle across the bed is not the same thickness. Diagonally its thicker and then narrows. I dont know if its noticeable in the photos below. If it was perpendicular to the edge of the bed steps could be at fault but here i don't know. If i print 100x100x10 5mm tall angby agniusm - General
OK. I printed large cylinder, well, not that large @ 100mm dia, in PLA. Most of that nasty ringing is gone. I have some faint diagonal ringing (3rd photo) but my thought is that it comes from X. The belt is pulling motor out of square (crappy CR10 bracket reused) and when it goes one direction belt twists to one side and vica versa. Could that be the cause of diagonal ringing? Next i now have conby agniusm - General
Its kind off weird. I have more on the y and less on the x but also the shape of it is different. Btw its not on the corners, its along all the way. X is having repeated diagonal lines and its like you said more or less when the light hits ar certain angle. Pla feels a lot less than petg. I will get more photos at correct angle.by agniusm - General
Thanks. So larger motor and wider belt is not helping? I did print bechies with almost no ghosting or ringing, but they are small objects. Ciuld be that something i changed in slicer or firmware or smaller object would have lesser effect?by agniusm - General
So i have built my 3D printer. Frame came from CR10 but there is not much left of it except 3 of the motors (X taken from Y and dual Z). My printer is running DuetWIFI, has 5" LCD panelDue, IR bed probe, E3D titan aero, NEMA23 on y axis, 420x410x8mm precision alumiunium plate with .5mm PEI on top and 1kW keenovo heater, running on preloaded Bosch Rexroth 15mm rails. X axis runs on LM THK 22mm liby agniusm - General
