Endstop Z axis MPCNC Burly
thingiverse
25mm version only. I guess it would work with a one inch tube too since the mounting plug is expandable somewhat. This is my solution to the homing of the Z axis on the MPCNC Burly. It consists of a 3mm rod (steel, brass or anything really) glued into a bracket and running through a guide on the top of the Z axis tubing. Parts needed: 1 M4x40 screw and a hex nut. 2 M3x15 with nuts 1 3mm rod with a smooth surface. I have 80mm travel and rod length is about 160mm so adding a 100mm to your travel should do it. 1 micro switch with lever for 2.5mm mounting holes and suitable screws, the bracket is 2mm thick. Print the parts, no support should be needed, use 35% infill. Carefully drill the 3mm in the rod bracket hole to snugly fit the rod. Use a rod a bit longer than expected and shorten it until homing at a safe and convenient position. Tie the cable down.
