CNC 3018 Optical Endstop Mount

thingiverse

These upgrade parts for the "Woodpecker CNC 3018" and similar engraving machines (1610, 2418) are designed to add optical end stops to the machine. To achieve this, you will need a mainboard with end stop headers, just like the stock board, and you must enable them in your firmware ($22=1 in grbl). The Y axis does not require any parts printing; instead, follow the setup shown in the pictures above. You will need an M3 T-nut to fit into the grooves at the bottom of the platform and a long M3 screw, which acts as a flag to block the sensor and allows for adjustable positioning. For the X axis, print both required parts and attach them according to the setup shown above. When attaching the flag, drill a small hole in the bottom of the X carriage and use an M3 tap to secure it with an M3 screw.
