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? https://reprap.org/forum/read.php?70,316512,316512#msg-316512 Sat, 08 Aug 2026 11:46:25 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?70,316512,893350#msg-893350 https://reprap.org/forum/read.php?70,316512,893350#msg-893350 tombrazier Plastic Extruder Working Group Mon, 28 Aug 2023 15:38:32 -0400 https://reprap.org/forum/read.php?70,316512,316569#msg-316569 https://reprap.org/forum/read.php?70,316512,316569#msg-316569 New light extruder concept out of bolt
