Hard maple will burn if your slow the feedrate to make direction changes, I like using a raster roolpath in line with the wood grain and extending off of the ends. Extending off the ends allows the machine to slow and stop off if the wood and prevents burns…
What do I mean by extending off the edges? Well, i mean like whats shown on this video of surfacing a cupped pine board…
You’ll want a rather thin pass depth is hard maple will chip, and I would reccomend a planer if your board will fit
My experience, and I do a lot of hard maple with other woods for cutting boards. These are my settings for the XCP.
I set the raster to Y axis (found it has the cleanest plane, both on the XC and XCP). I also use a 1.5" planer bit (non-affiliated link below). I use the default 40% step-over, but I think 50% would work okay also for a slightly faster plane.
I set the board size, but the cut rectangle I set to board length + 4" (to over cut, I don’t like it planing X axis). I set the board width to +2". I also pull the position of X to -1" and Y to -2".
If my boards are pretty flat (mine are typically glued/laminated), you might only need 2-3 passes. I watch it and let it continue consecutive passes until it is flattened. When I think it is done, on the next ‘border’ run, I cancel the carve in Easel.
My prior way was a single pass, check, re-run the setup and start again. This allowed me to let the machine run until I think it is ready.
