Two-sided milling

@jwr

And that still doesn’t tell me much about what I should expect from the BitZero V2: ±1mm? ±0.1mm?

(Much) lower than 0.1mm. Interestingly I have a hard time digging for actual numbers in the forum, but here’s a mention of “well sub 0.001”) from @mikep, though it was probably with another G-code sender and a custom touch probe macro

Precision Probing

I’ve found probing to be much more accurate the slower the probe cycle. I get very repeatable results with a fast probe (now you’ve got a good idea where the probe actually is so the probe distance can be short) and then a very slow probe again. Homing by default works on a “seek” then “fine” method, you can do the same on a probe. I haven’t found a need to average, multiple slow probes get me the same answer (well sub .001")
