I'm having trouble keeping my print head from ramming into the platter after I generate gcode with slicer.
Below is a few lines.
I see the nozzle is lifted to 5000 ?? (line 5) but then after heating goes to 0.2 and rams into platter. Is there somewhere where I can make sure all units are the same ??.
