Adding Run-Hold switches to a CNC machine #3Dprinting
by Anne Barela
The Smell of Molten Projects in the Morning blog posts about adding run/hold switches to the CNC 3018XL.
Although the bCNC GUI has conspicuous Run / Hold buttons, it’s easier to poke a physical switch when you really really need a pause in the action or have finished a (manual) tool change. Rather than the separate button box I built for the frameless MPCNC, I designed a chunky switch holder for the CNC 3018XL’s gantry plate.
A multi-pack of RepRap-style printer wiring produced the cable, intended for a stepper motor and complete with a 4-pin Dupont socket housing installed on one end. The housing was chopped down to three pins, tucking the fourth wire into a single-pin housing, and plugged them into the CAMtool V3.3 board.
