Having a bit of a problem with my v3. It had been working fine, then suddenly 'locked up' X and Z axis will not move. Motors are holding, and resist being turned by hand. Any attempt to jog the position shows no movement of the motor, and no increase/decrease in position in the software. BUT, if I try to move the Y axis, it will unlock all the motors, show a position change in the software, then relock all the motors when the move finishes, but the Y-axis motor doesn't actually move. I've tried two different computers, two different USB cables, and two different GRBL senders, to eliminate the possibility of a failure there. I've allowed it to cool overnight in case it was a thermal issue. I've also reloaded the GRBL firmware in case it got corrupted. I've changed motors. Running a 24V switchmode power supply, tried bCNC and UGS, and a Raspberry Pi and a laptop, both of which previously worked. The power supply is putting out 24V, and is also running the Pi, so it's not dropping out. At this point, the only thing I can come up with is the XPro board itself has failed. Any suggestions??
