  • Wipe down the build plate regularly with IPA to help keep it clean; I do this as part of my pre-print workflow. That and scrubbing the nozzle with a brass wire brush to help keep burnt filament getting into my print.

    How hot is your shed? Depending on your shed temp, some filaments actually like it hot. I have a PLA filament that likes to print at 220C and in an ambient enclosure temp of 90F.

    If your shed is near 120F-140F, its perfect for ABS/ASA (be mindful of VOCs); maybe consider switching filaments while its hot out - making lemonade out of lemons and all that.

    cheers



  • Here are some things to try:

    • make sure you have properly cleaned the new bed; ipa or dish soap. I have gone so far as lightly sand my new pei sheets with high grit sand paper to improve adhesion. Try the list below before considering sanding.
    • bed temp: as you mentioned a cooler bed temp may improve corner curling. 50c or just yolo it and turn it off
    • sounds like you’re printing with PLA: maybe slightly lower your hot end temp.
    • mouse ears at the corners may help keep them from curling.
    • make sure your printer isn’t catching a cool breeze.
