Are you sure it does not come from a bad connexion/solder with your endstops ?

To check it, unplug your Endstops and replace them by jumpers or short wires female DUPONT to female DUPONT.
Power on the RS-CNC32 and check if you still see the ?? If not, that's mean the problem come from your Endstops, check their wiring and solders. And do not forget to use shielded cables for them.

WARNING : Be careful do not do large movements with your CNC with the jumpers or short wires female DUPONT to female DUPONT in place. In this config, for the RS-CNC there is no endstops.

Yes I have tryed with jumpers on the endstops. Still the same.
