Z motor power while doing mesh levelling
-
Question: for doing a home in Z it is "safe" to reduce the power on the Z motors. But what about the mesh levelling, is there a way to reduce the power on Z motors with M913 during the mesh calibration trigered by G29?

If it works without skipping steps then it is fine.
What firmware are you running?
With firmware v3 G29 executes mesh.g and you can set/reset the motor currents there.
Of course that file must also contain the commands needed to do the probing like M557 to set the probing grid size, the G1/G30 commands to set the Z=0 datum and the G29 S0 to initiate the actual probing.

M557 could be set in config.g and/or inside mesh.g if you want. As long as it's set once somewhere before you run G29.
Setting Z=0 should be done before G29, but it could be done in homeall or elsewhere.
At minimum mesh.g would need G29 S0, but you can add as much or as little of the pre preparations as you want to it.
