using acrylic mounted on top of bed

Postby hmerzin » 2016-Jan-Fri-12-Jan

I've been trying to print with acrylic for platform adhesion for PLA. I can't seem to find the GCODE for preventing the head for going all the way down to the bed instead of stopping at the surface of the acrylic. I tried to set the M212 Z offset to the thickness of the acrylic but it only gouges the acrylic and digs in.. Any suggestions??

The probe can not sense the metal bed underneath the acrylic (IIRC it only has about a 3 or 4mm range). To work around that you could place some aluminum tape where the probe "looks" for the metal bed.
