I was cutting 3/4" MDF on a PRS Standard at 3ips when half way through a file, the Gecko driver for the Y axis failed (fortunately, SB tech support helped me get it fixed). I asked what they felt the top speed should be and they suggested that 3ips is near the limit, but that it should be able to cut it. In addition to the driver failure, the noise from cutting was screaming loud. I'm wondering what speed other PRS Standard users are cutting MDF at and would appreciate any insight.
These were my settings:
PRS Standard with HSD 4hp Spindle
3ips
1/4" End Mill (Onsrud 52-910)
Stepdown = .25"
Chip Load = .006
Spindle RPM = 15,000
