I've just wasted an entire day trying to debug a program I wrote, only to discover the problem is with my feed rates. I just used a stop watch to time a 1 inch travel at f10. It should take 6 seconds, but it takes between 10 and 11! Spindle and Feed pots are both set to 100% but even when I use M49, my little test still takes 10 seconds. Is this normal? Is there something I can do to calibrate it?
The machine is a 1995 VMC15RT. Specifically, I'm trying to synch the spindle with the z-axis similar to a tapping cycle. The result I'm getting isn't even close to what it should be.
Any help or suggestions would be greatly appreciated.
