@carlinicompetizione I don't know why leaving out the M208 command would cause this issue, because if it is missing, the firmware sets a default of 0 (for minimum) and/or 200 (for maximum) in each axis. eg if I comment out all M208 commands in my config.g, then send M208 after a restart, it reports:

M208 Axis limits (mm) X0.0:200.0, Y0.0:200.0, Z0.0:200.0
