Since I am using bcnc to control my router I searched for an easy way to stop the router quickly if something goes wrong. I realized that the controller board itself offers three contacts that are evaluated by grbl:

Reset/Abort (A0) Feed Hold (A1) Cycle Start/Stop(A2)

To use this contacts safely I designed a combined case and mount. I also created a pcb for the push buttons (12x12mm). The gerber files for the copper bottom side, the board-profile and the drill file are also attached. Since I milled the pcb this files are mirrored vertically.

To mount the case I used following things: 4 nuts M3 4 screws M3x16mm 1 screw M5x16mm 1 washer 5.3mm (DIN 125) 1 t-slot-nut M5 (for 2020 profiles) Dupunt connectors and cable
