New Nema 17s for Z Axis Not Working
Hi there, having so much fun with my A5S (he says sarcastically). I swapped out the Z axis lead screws (they were bent) with 2mm lead version. Not enough torque in stock steppers to handle so "upgraded" to new Nema 17s from TwoTrees:
I assumed it would be a straight swap as they are both 4 pin but neither seem to be powering on/turning.
X and Y axis are working, just not the Z.
Can someone please advise what I am missing?
PS lots of great information on this forum for which I am very grateful!
