Quad z independent motor movement.
-
I would like to see a paramater added to G1 command for example G1 M5 Z10 which would say move motor 5 positive 10 and leave the remainder z motors stationary so that on bigger builds you can get the bed closer to level prior to running a G32 mechanically leveling the bed. This is critical for bigger dual gantry machines as if the one head corner is close and the opposite corner is 20 mm away the secondary head will crash into the bed before it can probe the other corner.

What you can do is what I did.
Each Z stepper has it's own endstop sensor.
With this you can home using G1 H1 moves as you would for X and Y.
I designed and printed adjustable mounts for the endstop sensors so I can tweak their position to get the bed very nearly level using the G1 H1 approach and then finish the leveling using G32.
