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

    I had to cut my printing speed back to keep from warping. I don’t recall what i changed it to but it’s roughly half what i printed pla with.
