I haven’t had a need yet for an e-Stop switch, but I figured I should go ahead and install it before the need arises! I’m still amazed at how quickly I can model a part, create the CAM setup, and then create the part on the CNC machine. It took less than an hour to model the bracket, create the CAM setup and toolpaths, and produce a g-code file to bring out to my machine, all with Fusion 360. I cut the bracket from some scrap 0.25” plywood and mounted the switch on the front of the machine. One side of the switch was wired to pin 10 on the Gecko G540 breakout and the other side connected to ground on the power supply.
