It seems my X and Y have been reversed somehow. The machine is currently sitting 55mm above the center point of the stock, yet Makerverse thinks it is at -55mm on the Y axis. Same thing for Z - it’s just flipped.

Any idea how this happened or what I might do to reset it? I did a full calibration this morning, and just tried resetting chains. It also seems to have lost it’s ability to run a homing sequence. It seems to think Home is down in the left corner. I thought resetting chains would fix that, but it didn’t.
