Hi , I am making some progress on MPCNC - thanks to some advice on this forum!!
My machine is not rectangular- so I haven’t christened either axis X or Y yet,
I have DIY wiried stepper motors (nema 17) in series as per - https://www.v1engineering.com/assembly/wiring-the-steppers/
On one axis the wiring seems to have worked - motors turn in opposite direction
But on the other axis the motors turn the same way - confusing thing is they are wired the same
I have tried swapping a couple of wires over (the two wires that connect the two steppers ) but quickly cut power as got disturbing sound and heat in driver
I dissconnected wiring and set about testing the motor one by one - the both behave okay when wired to individual cable - they turn in same direction with same input and wired with same colour cable
I tested to see if continuity in wiring on stepper (with no power connected)- both motor behaved the same in that there was zero resistance between blue and red , zero resistance green and black
My question is - Is there any chance one motor has colour wires mixed up ?
