      Hi, im struggling to enable closed loop mode on my setup. I get warning "Driver 30.0 warning: tuning/calibration failed" followed by error "M569.6: Driver 30.0 basic tuning failed, the measured motion was inconsistent". I increased motor current to 5A as suggested in other thread. I also disconnected motor from gantry, so it can move freely. I can see motor rotating and returning to position during calibration, but it always fails. This is my configuration:

      M569.1 P30.0 T2 C1000
      M569 P30.0 S0 D4
      M569.6 P30.0 V1

      Thank you for your help.
