I’ve attached the file (Shapeoko 4 XL Leveling.c2d (42.8 KB) I plan to use for the leveling tool path, but would really appreciate it if someone who’s done this before could take a look and confirm I’ve got it setup correctly, OR correct anything I’ve messed up.
I used the cutting dimensions for the XL of 33"(X) x 17.5"(Y) and created a serpentine tool path 1/2" apart at a depth of 0.01". Following earlier advice, I’ll mark the cutting area with pencil lines and repeat the run after adjusting Z-zero down 0.01" each time until the area is clean.
I do wish I’d listen to that voice in the back of my head a little more seriously sometimes. That crossed my mind, but for whatever reason, convinced myself that I needed to cut square to the edges - completely disregarding the limits the arcs would exceed.
Decent results today, but with a few limiter hits and some ‘figuring it out’.
Hard part for me was determining X/Y zero. I used the Rapid location to SW which was fairly accurate. I knew it could jog over the front edge to reach BitSetter, but wasn’t sure how much of that was valid cut area, so I used the SW position to be safe.
Using 17.5” as the height (Y), as defined in the product specs for XL, it hit the limiter a couple of times, so I reasoned that I could have set zero at least an inch south of where I did.
After additional incremental perimeter passes I cut all the way forward giving a clean edge off the front - not without an ‘O-F!’ moment as it came out over the SE corner near BitSetter. All good, but we won’t do that again.
Good opportunity to learn a few more things, but as a former product person, can’t help but think some machine-specific presets for waste board leveling would be good to have, at least on the ‘nice to have’ list.
Thanks @Tod1d and others for help and recommendations.
