Y axis moves double the amout it should

could it be because i wired it wrong?

For now i changed the value in estle cam to double the amount it should be but i am not realy satisfied with that solution.



Nope, not a wiring issue. Where did you get the parts?

Are the model numbers on all 4 steppers the same?

Are the pulleys on the steppers all 16 tooth?

Pulleys are 16 teeth and steppers are all the same

Make sure that all jumpers are on under the stepper drivers. Since Y is the one with the issue, particularly check it to make sure all 3 jumpers are in place. If they are, and you’re still having problems, you can change the movement in firmware.

You should be able to change:

#define DEFAULT_AXIS_STEPS_PER_UNIT { 200, 200, 800, 200 }


#define DEFAULT_AXIS_STEPS_PER_UNIT { 200, 100, 800, 200 }
