Hey all, has anyone used Mattercontrol's 13 point calibration? If so, does it apply a correction to the gcode it generates when it slices files, or does it apply an offset to any gcode, ie will that calibration map work with gcode generated by an external slicer?

I'm 99% sure it applies the correction to imported gcode. I used to have the 13 point calibration and use Kisslicer. If it wasn't applying a correction to my gcode, the head would have crashed into the bed at several points.

Yes - it augments the gcode directly to compensate for any warping/tilting of the bed. A simple offset could not account for a warped (not flat) bed - thus the gcode is modified to accommodate.
