This is my home built 3d FDM plastic extrusion printer. I'm on my 6th revision of it and finally getting ready to post build instructions for it.

  • Great job, BTW :)

  • @jweismiller Thanks for the advice! I'll try that. BTW, I'm only using 1/8 steppings, if that affects the sound.  My reasoning is that at 1/8 steppings I'm already throwing a step pulse every 3 or so stepper timer interrupts, when the code would prefer every 8. I figured 1/16 steppings would be a bit harsh.

  • I have my MakerBot running at 16X without any problems on the Gen 3 electronics.

  • If you are using the pololu drivers, it sounds like you have the current set too high on the steppers. You should set the current to zero on each axis, and then slowly increase the current until you can not make the axis skip by hand anymore.
