Here share the solution to resolve Xhorse Dolphin XP005 Error Code 29.
Use Dolphin XP005 to cut key, it can’t cut key normally. Try the height adjustment, the X-axis motor test and the Z-axis motor test, all fail and get the error code: 29. I also do a conductivity test, the cutter and clamp are fine, but the probe and clamp are showing always tests on.
The milling cutter shorted out, please follow the following post to check

After that, clean the iron filings inside.
