General Mach Discussion / How fast is your G00 Rapids?
« on: July 16, 2007, 03:17:53 AM »
Just wondering how fast others in the forums are getting thier machines to run at. Mine only does 70ipm running Mach 3 at 25khz. I have a 3.6G processor and can run Mach at 35khz, but the servo's are smoother during 3 axis contouring if I keep the Mach controller at 25khz. I guess my mistake was the high resolution encoders. I think I have more resolution using the 512 count encoder wheels than I would ever need. Other than that, the servo's are geared 2:1 and the ballscrews are .100" IPT. I was really hoping to get to 150ipm rapids. I think that's pleanty fast for a open table bridgeport mill. Any faster than that and I would think that a programming error could cause some serious damage, bodily as well as mechanically.
