I’m not actually sure if that’s what’s happening here, but I’m seeing it with both HDPE and Plywood…I assume I’d see it with other materials, but that’s all I’ve been cutting so far.
Hard to tell if it’s in a certain direction only (X,Y) or if it’s only happening on arcs, but you can see how most of the larger circular cuts here have chunks either missing or left behind from the spindle jerking around.
I was running with a .125" endmill at .0625" stepdown, 60ipm feed, 20ipm plunge.
I’ve checked all of my connections, and nothing seems loose.
Hmmm. Original SO3 instructions don’t seem to apply to the XXL…there’s almost no play in the motor mounts, so I can’t use that to tighten the belts…am I missing something?
