One customer gave the feedback that the cutter of his Xhorse Condor Mini Plus stopped moving before cutting a HU66 blade.
Here is how Xhorsevvdi technician troubleshoots,
1.Do Main motor test (Path: Device Information>>Motor Measurement>>Main motor test)
1)See if the cutter rotates
2)Keep the cover down during the test
The cutter won’t rotate.
Replace driver board.
Hope this could help!
