Here is the suggestion from Xhorse engineer:

MINI PLUS 2 main axis rotation abnormality
Fault phenomenon 1: The cutter rotates normally when starting to cut the key, the speed decreases significantly or simply stop rotating and receive an error message of 20 when the cutter comes into contact with the key.

Fault phenomenon 2: When starting to cut the key, the cutter does not rotate at all;

Solution: There are two possible causes for this malfunction,
1: Check if the connection cable of the main axis drive board has poor contact, and try unplugging the four circled plugs in the drive board on the right, pay special attention to the plug inside the yellow circle, as there may be poor contact between the pins;
2: If there are no problem with the plug connection cable, it means that the main axis drive board is damaged and needs to be replaced. The drive board is located next to the emergency stop switch inside the machine. (The picture on the right shows the appearance of the driver board)
