Hi Rich:

  Yes, those cutoffs are due to trying an undercut.

It's maybe a stupid question, but what is an undercut?

Galil / Re: Need help with basic VFD spindle setup - 0 to 10 VDC, Forward & Reverse

If you get the 0 to 10V output to work out from your terminal board then you have to configure the VFD to run 330rpm at 0V and 5380rpm at 10V. All VFD's I have been working on have a lot of parameters making all such sort of setups possible.

The phrase "CV" stands for Constant Velocity.

The CV feedrate is the maximum allowed feedrate when Mach3 is "cutting corners". Mach slows down to this feedrate if it's lower than the programmed feedrate when cutting corners in constant velocity mode. If this feedrate is to low Mach behaves almost as in exact stop. A feedrate of 1 (inches or mm) per minute is VERY slow and makes the movement almost like exact stop.

You also may want to uncheck the "Stop CV on angles > x Degrees" under the Config > General Config menu page.

Enter the desired CV feedrate in the DRO next to the CV feedrate button on the setting page, then hit enter.

And make sure your CV distance and CV feedrate leds is on.
