Mostly Printed CNC (MPCNC) Sensorless Endstop

thingiverse

This is designed to fit snugly onto the axis frame conduits, creating a flat surface for crashes. Marlin's sensorless homing feature pairs perfectly with this add-on. To ensure your frame is square from the start, install these endstops directly opposite each other. Use M4 nuts and bolts to securely fasten them to the conduit. If your frame already has a perfect 90-degree angle between its axes, you won't need any additional hardware. Simply place the endstops in position. My personal preference is to home my X and Y axes at their maximum points (X_Max and Y_Max). However, I've found that my Burly MPCNC only requires these spacers on the Y axis, while the X axis doesn't need them. Your specific setup may vary. Some key notes: I printed these parts using PETG filament, which provides a flexible yet durable material that can be installed without cracking. While PLA might not work as well in this application, it's worth experimenting to find what works best for your build.
