Here share the solution to resolve Xhorse Dolphin XP005 Error Code 29.
Use Dolphin XP005 to cut key, it cannot cut the key normally. Try the height level adjustment, X axis motor test and Z axis motor test, all fails and get the error code: 29. I also do a conductivity test, the cutter and clamp is ok, but probe and clamp always shows testing.

After that, clean the iron filings inside.
