G320 step error voltage to control feedrate?
- So I have all three of my axis running on my new dovetail mill using
the g320's and 1100oz/in servos. This is quite a step-up over my other
I see where the G320's have a voltage output available on a test point
that is correlated to the lead/lag step error. It would be nice if
there was an easy way to get the step error into Mach3 so that if the
drive was running behind and the error rate was increasing then Mach3
would lower the feedrate using the feedrate override.
I assume I could do this with an input line using an A/D convertor on
a PIC chip that raises a line to slow down and another to speed up?
Has anyone taken a look at this?
