RF30 X-Axis Endstop Toggle Switch Mount

thingiverse

This is a little mount / cover to use a single 3-way toggle switch as a min/max endstop along with the pre-existing sliding bumpers on the Rong Fu RF-30 mill drill. I couldn't find a NC 3-way toggle switch, so I'm running a traditionally-less-failsafe NO circuit. I figured it's a toss-up since the likelihood of metal chips getting into the housing for a NC rig and shorting it to fail closed is about the same as anything coming apart in the NO circuit and failing it open. Either way, make sure you have an emergency kill that works and only use your endstops while you're actively paying attention to the machine.
