I don’t know. I think the offsets are inconsistent. I’ve been keeping track of my Z offsets because they seem to cause tertiary problems. I’m doing a test run of an 8" Yggdrasil relief with the router turned off and the z-stop set WAY above the project board. I’m 62.5mm between the bottom of the first router clamp and the top of a z-axis motor. My cut will move the z-axis down to 52.0mm(same measurement). I haven’t cut anything with my M4 yet. However, I’ve done some dry runs. I noticed that if I don’t have my zhome/zstop set at a fair height, I can run into a 15mm error. 15mm Position Error While Moving Investigation - #19 by bar
So I loosened my router chuck and dropped the bit a cm.
But yes. I have to be careful to set the Z-axis carefully.
Unrelated, Thank you for all of your development work! I’ve been lurking for a long time. I might actually have some small PRs in an age or two. Perhaps something to send telemetry and errors to a central log server for QA? It would have to be secure and not an invasion of privacy, so it could be better that this take a longer time to develop. CISSP with 3yrs of Criminal Justice, hackspace owner for 15yrs.
