Have a question while setting up the delta endstops axis movements, I continue to hit some walls. Every time I try to move what I think is the z axis, i notice that it moves significantly slower then a the x, and y.
On top of that when I cant seem to figure out how to switch from Cartesian mode to Delta. I use the M270 mcode that Elias states in his guide. But when I send “M270 S3” in the terminal, the printer still acts as if its Cartesian. Not sure whats going on here one bit
Heres a video showing whats going on.

It will be determined by soft_end_stop_min/max_
