Yea, I have a pile of “well that didn’t work” plywood under my chopsaw now. So far my biggest issue is getting the zero back to where it’s supposed to be after a bit change when carving stuff. If I’d just remember to write down my x and y offset from my endstops I’d probably be golden! I did make a z probe finally. Need to pick up a cheap set of shims from harbor freight so I can steal the thinnest blade for it still. I’m using a chunk of aluminum from an expansion port cover from the back of a computer right now. Soldered an alligator clip to the other wire and just clamp it to the bit and hit the z home button, works every time so far!
