New AR8 Pro, with a newby question, is the mill plane set up in VCarve or is it preset in the pendant? Can you/how do you control the depth of cut? Or is it also preset in the mill plane function?

On my 8pro there is a file set up in the pendant that fly cuts the spoilboard. I think it cuts about 1/16” deep but never measured just going by eyesight. All I ever do is put my 1.5” surfacing bit in and start the file.

Sounds like you have some basic things to get under control here. You set your Z-height at every tool change (and typically before every cut operation - make it a habit). If you are milling the spoil board, you will set your z-height to the top surface of the spoil board and run the program. My Axiom (bought used) didn't come with the default programs so I programmed my own to just take 1mm off the surface once the z-axis was zeroed to the top of the spoil board.

When making your own program for milling the spoilboard, does it make any difference whether one uses an offset or a raster strategy?

Joe... The best results seem to come from a 90* raster (Y direction). The offset toolpath option introduces too many direction changes that product flex which is exaggerated by the larger (2.5" in my case) bit. Video uses a 3/4", I think
Here is a short video showing how I do it:

Thanks Gary. Makes perfect sense when explained that way. Video confirmed my thoughts too that it would be a profile plus pocket toolpath.

Same here, I found out the hard way that I need to minimize the X direction passes. I was able to tweak my Y axis alignment on the carriage to get an imperceptible pass step in the Y direction but not in the X. Any misalignment of the X or Y axis is really magnified with a larger diameter tool.
I also was not aware of that customization available on the raster tool path. I will definitely use that. Thanks Gary!
