I have some very consistent issues with warping when printing ASA/ABS, which is really annoying since I’m trying to print my voron parts. It’s not warping massively, but enough to mess things up.

I print with these general settings, on a textured PEI flex-plate.

  • heated chamber @ 45-47C (can’t go much higher)
  • bed temp @105C
  • first layer 255C, other layers 245C
  • fan off, unless it’s an overhang >=50% or layer time is <10s. Fan maxes out @70% unless bridging.
  • speed 200/120 mm/s inner/outer walls
  • first layer 50mm/s, 80mm/s infill

I’ve tried both with my regular Z-offset which creates a good uniform first layer, and slightly lower to kind of push it more on to the plate (but worse looking)

  • I’ve cleaned the plate with pure IPA
  • I’ve tried glue stick
  • I’ve tried brim both skirts/mouse ears, which help but don’t eliminate it. (5mm, 0.15mm space)

ABS seems to be a little easier to print than the ASA. I’m using filament from Polymaker

      makes sense. already have better boards lined up for both printers, pending time off work to install and rewire. Honestly I expect assorted smoke and burning from creality stock boards and the ones I’ve sold or given away were sent off with aftermarket controllers that the internet and myself have more faith in. This was one of the last 2 functioning stock boards I’ve ive been using for 3d printing experiments I don’t want to do on more expensive gear.
