Hi all, Short version: Can you replace the magnet from the XYZ touch probe with a wire run through the drag chains and connected to the spindle casing? Long version: I’m horrible at remembering to connect the magnet when using the XYZ touch probe. Luckily, I do XY first, so all it does is shove …

Depending on your router/spindle, you might be able to wire it to the frame, and never have to think about it. Another option is a 3-wire 3D probe. If mine cable isn’t connected, the machine will tell me “Probe Error”, and won’t even move.

I worked with a standard Z probe for a couple of years (starting with my X-Carve in 2016) before I realized the clip (or magnet) was totally unnecessary and inconvenient. You’re merely completing a simple circuit, so why not utilize a microswitch? This video shows my first version which used a scrol…

Cool, that’s simpler than running a line through the drag chains… Thanks

Ok, that it’s completing the circuit via the ground makes more sense than what I was thinking (that it was going through the rails and bearings), and it’ll be much simpler to just run a line to the ground rather than through the drag chains all the way to the spindle. Thanks

Hey Stefan, but the spindle PE wire actually does usually run through all the drag chains – it’s inside the spindle motor cable :wink: Usually in industry, the stepper motor cables are shielded and contain a PE wire . The Onefinity however unfortunately has no shielded stepper cables (hence its sus…

How accurate and repeatable is that homemade Z probe? As much as the touch probe?

Yes, it’s extremely accurate. I tested it +/- 10mm from the ideal ‘target’ point (between 4 & 10 on the scale) and it repeated better than .001" every time (I don’t recall the exact numbers, but I did run an extensive test on it). Certainly more than accurate enough for anything I’m cutting. The on…
