A mod to protect limit switches

I used some stock Inventables parts to create a hard stop for both the right and left y-axis stepper plates. These hard stops have several benefits.

(1) prevents crushing of the limit switches
(2) provides a reference for squaring the x-axis every time XCarve is powered on

It is composed of four parts, one set for each side.

  • an M5 25mm bolt
  • a post-assembly t-nut (used to hold and position the M5 bolt in the y-axis makerslides)
  • a preassembly t-nut (the switch protection stop)
  • an M5 nut (jammed against the preassembly t-nut, to hold it in position)
