Howdy,
My belt drive cnc was built for milling foamboard but recently thought it would be nice to cut plywood and acrylic. Basic spec: nema 24, t5 belt, Gecko, Mach 3, 900w spindle (12-26,000rpm)
I was reading this very helpful F&S thread below, which gives a good indication of what i should be aiming for. However as my machine uses, belts and v-groove bearings and is a light weight design for speed I am wondering if there are setting I can use which will at least give me a chance of cutting something denser with multiple passed with reasonable success.

I can see from cutting through 9mm ply using 2mm passes that the tip of the single flute cutter is blacking pretty quickly. The timber is not blackening but 20mm/s is not very fast is it ha ha and probably part of the problem.
It could be that the whole machine needs rebuilt to cut more resistant materials but any indication of
where I can look first to at least try to get the machine i've got cutting ply would be useful.
Thanks.
