MKS Servo42C: jitter or not react to G-codes
Symptom
Symptom
The steppers jitters at S42C calibration.
Solution
Solution
Different stepper manufacturers have different pin outs for internal coils. Please swap the wires with one of the color sequence in the picture.
Symptom
Symptom
When sending any G-code commands (homing, movements, etc) to S42C, the stepper jitters or just stalls, but S42C calibration still works well.
Solution
Solution
The pins at the back side of S42C PCB touch or are too near to the stepper body and create short-circuit. Trim the pins very carefully and don't knock off nearby tiny electronic elements.
