I finally have my printer going that I started building 6 or so years ago. It seems to print fine, but some steppers are much noisier and hotter than others. Wilson TS design, 24v, smoothieboard 1.0 X, Y and extruder are all the same nema 17 steppers, Kysan 1124090, the X and extruder are fine and rather quiet, but the Y stepper is noticeably warmer and much much louder. I have tried turning down the current on Y but I am down to 1.0 from 1.5 with no change.
the 2 Z steppers are wired in parralel, and are shoter nema 17s than the others, rated for .75 amps. They constantly have a humming/buzzing sound and are getting hot enough that the 3d printed mount they are bolted to has gotten soft and sagging.
This is the only real project I have done involving steppers and such so don't have my own experience to draw from, can any of you help me figure out what I am doing wrong or at least keep the tempurature of the Z steppers to something reasonable?
Thanks
