To use FSR's with the smoothieboard an aux board is needed to interface the FSR's to the smoothieboard's endstop input. Smoothieware will accept this input as if it was a simple mechanical switch.

JohnSL (Github) has created such a board. It is available via TriD Printing & UltiBots. See John's blog post about the board. This board is powered from the endstop pins.

The Deltabot group is where most discussion on using FSR's is located.
Topics to look for are:

  • Alternative boards like the arduino mini.
  • WingWong's trinket derived design.
  • Mounting of FSR's
