CNC 3018 Optical Endstop Mount

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 do this you need a mainboard with end stop headers (like the stock board) and you will need to enable them in your firmware ($22=1 in grbl).

The Y axis does not need any parts printing for it - see the pictures above to see how I set it up. You will need an M3 T-nut to fit the grooves in the bottom of the platform and a long M3 screw (this acts as a flag to block the sensor and doing it like this allows the position to be adjusted).

For the X axis, print both parts and attach them as shown above. For the flag, you should drill a small hole in the bottom of the X carriage and use an M3 tap to attach it with an M3 screw.

These are the optical sensors I used: https://www.ebay.co.uk/itm/3x-Optical-End-Stop-Endstop-Limit-Switch-Cable-for-3D-Printer-Ramps-1-4-Rep-JX-/132778404195
