MPCNC 525 Z Positive Endstop

thingiverse

I use GRBL as my controller for my MPCNC because I prefer it over Marlin. When homing the CNC, I start by moving the Z-axis up and away from the workpiece, then proceed to x and y. After searching Thingiverse, I couldn't find a solution that preserved the full Z height without compromise. Therefore, I designed this small part, which performs surprisingly well. This component is detachable and attaches with a magnet obtained from your local home improvement store, secured by simply screwing in the switch. The magnet itself is a doughnut-shaped neodymium disc measuring 9.6mm in diameter and 1.5mm thick. You can find this specific type of magnet at: https://www.homedepot.com/p/MASTER-MAGNETICS-3-8-in-Neodymium-Rare-Earth-Magnet-Discs-12-per-Pack-07090HD/202526371 For those who want to remix or modify the design, I have uploaded it to Fusion 360: https://a360.co/2QB9ArI To keep the magnet securely in place, a small dot of ca glue is applied. When printing this component, support material is not required. Simply print with the two small holes facing downwards on your bed.
