Hollow or Threaded Shaft Stepper Motors
February 26, 2014 01:14PM
Has anyone tried boring out the center of the shaft of a NEMA 17 stepper motor? I was thinking of trying this to make a simpler extruder, to cut down on the size of the X-carriage platform on my prusa-mendel machine. I realize the firmware would change - that's ok.

The question is - if I start boring a 1.75mm or 3mm hole into the shaft, am I going to run into any magnets or electronics on the inside of the motor, or will I simply poke through the other side?
