Topic: pid tuning heatbed? (sudden extreme ABS warping)
I can only find info on tuning the heater of the hotend, not the bed. How do you do it?
I'm currently experiencing extreme warping with any size object in any place on the bed with any temp I used before (90-110), with either (the same) hairspray/ glue stick and the same filament.
I recently replaced the fiberglass mat on the bottom of the aluminum bed (put the old one back because of this) and reflashed with the official Marlin firmware so maybe I messed something up I'm unaware of.
