MakerGear M2 Z-axis Home Switch spacer to prevent drift of Z-home

thingiverse

I've noticed my Z-axis was wandering a bit after 5 or 10 prints, and the distance between the nozzle and bed was closing up. This would lead to tears in my tape or vinyl. After investigating a little, I discovered that every time the Z-axis homed, the switch was moving ever so slightly up the linear rail from being bumped during the homing process. I tightened the screws some more, but it still tended to drift, so I came up with a solution. To fix this issue, loosen the screws that hold the Z-home switch, slide it down a little. Then, clip a small piece of metal above it. Next, slide the switch up until it bottoms out against the spacer. Finally, tighten the screws and readjust your Z-axis home for probably the last time ever.
