Hi @cprezzi was grbl auto Square implemented in grbl-lpc?

What do you mean with auto square?

Double stepping motor and double endstop on y axis.
Each stepper motor moves independently until it activates its own endstop to adjust for mechanical imperfection.

This feautre is already implemented in marlin 2

Unfortunately this is not implemented.

thanks anyway

I think that squaring was implemented for grblHAL but am not sure.
