Troubleshoot after upgrading the firmware

Hi everyone,

I’ve have a former version of workbee cnc machine (1000x1000 screw driven)

I have a trouble issue with my duet 2 board and needed to reboot it and it was the time to update the last firmware (v3.3.0-1.2 ) on the board.

The problem is that I can’t home the machine.

• The y motors are not synchronised ( one motors is turn to the opposite way)
• The z can go down but can’t go up
• If the drill is in the middle of the table, the Z axis is going down, otherwise if I put manually the machine to position 0,0,0 and I clicked on home all, the machine is shaking.

See attached a video.

let me know if you have an idea.

Thank you !
