How to solve Xhorse Condor II Error Code 3

Problem:

I had a problem cutting Suzuki HU133R key blank. My Xhorse Condor II key cutting machine gave me error code 3. Not detected cutter. Any advice?

Solution:

First of all, do an Electrical Conductivity test.

In Condor II main menu, go to Settings->Machine Test-> Electrical Conductivity Measurement->Start Test
