Hi. There is a problem with calibration Cyflex wholesale-f900. When you start calibration, stop and write an error: NC 1126 Z calibration error. This happens after the endstop on Z off. It is not a mechanical or electrical. I checked. The guy who worked wrote texts about absolutely zero. He changed absolutely zero in the cnc parameters. Please help me. Maybe some one know or have a manual for xilog plus after input password
