I am going through calibration with Holey GUI (with v1.26 merged in) and have the exact issue as the topic subject. Unlike other posters, I have all lights on/flashing normally. Arduino is connected, motor tests passed, setting 12 o’clock in the calibration process went fine. Extending chain for pull-tight went fine.
When I press “Pull Chain Tight and Measure” the left motor sounds different, which is concerning (I’m avoiding removing the motor and inspecting the gears). What I don’t understand is, @Joshua what prompts GC to stop the motor, measure and then retract a little bit? Since this isn’t happening, I’m not getting the “Next” button on the screen. If I have a motor issue, is the fw or gc looking for some specific current threshold that represents “stalled”?
