Re: feeds and speeds Recommendations for belt drive cnc
Seem to be getting somewhere with the 12mm ply cutting after carrying out everyone's suggestions + tightening a slightly slack gantry. Thanks for everyone's help.
Feed 20mm/s
Speed 15,000rpm
3mm, two flute up cutter on 2mm deep passes
Mach3: Velocity 2500 and acceleration 500
I'm not getting the F/S issue of cutting corners i had before and neither is the cutter or timber burnt.
I am however still getting a furry edge, the block of wood was lightly sanded to get rid of the burr edge so they are not so prominent in this image.
I'm going to invest in a 3.175mm down cut and compression cutter to see where those results take me. At the moment i'm only intending to cut smaller parts and perhaps some cabinet doors at a later stage when I upgrade the gantry and whole machine to R&P.
Cheers

To get rid of the fuzzy top edge, use a downcut bit, and do NOT climb cut.
