I have yet to try ABS on my mini, but have read from others about using kapton or painters tape to improve adhesion. How is this done with a self leveling table? Do I need to tweak the Gcode to compensate for the tape thickness?
ABS should stick great to the PEI bed. Much better than kapton or painters tape.
The problem I have with ABS is getting it off the bed.
ABS seems extremely reliable to me on the PEI bed.
Adjust the nozzle height to vary adhesion. With the autolevel systems, the only option is to use software. The z-offset g-code setting in slicing software allows for this. Use a positive number to raise the nozzle and negative number to lower the nozzle. A .1-.3 typically helps with object removal.
