Zmax is down.

It occurs to be (from my long trudge through Delta-dom), that I could get by without endstops on the new printer if I placed the extruder in the middle (call it 0,0), leave the bed at full down, then determine the exact height of the Z stage (currently 353.3mm)

I’ve found Z Max Pos in the Firmware, but I’m not sure how to tell the printer ‘hey, turn on the motors, Z currently equals 353.3mm’

Thoughts?

You don’t need endstops on cartesians. Just throw your X/Y/Z to 0, and then do G92 X0 Y0 Z0 and remove any G28’s from your start gcode.

You can also use this to fool the printer into thinking it’s somewhere it’s not, so that you can effectively bypass the max/min limits so they can be set appropriately.
