How did you program the VFD to use that resistor? I just hit this same problem on my Slant this week after swapping to the 3500rpm pulley for some smaller 5C work.


EDIT: Nevermind... just...

I forgot about the instructions! D'oh!

Following those, Fusion generates the toolpath in simulation in what looks to be just right. In posting it though, I don't know how else to describe the...

Works like a charm! Thanks Adam!

Now if only I could figure out the G76 code that Fusion outputs through your post... :D

Lee, I think I may have stumbled on a solution for this if you're still having problems with it.

Interestingly enough, I have the opposite issue at the moment with Fusion... it thinks my parting...

I will give that a try. Stand by.

I've tried isolating the power input to pins 7 and 9 by utilizing a CC power supply, which doesn't seem to change the results.

And I just realized I made a typo above. When the spindle is turned...

In all the searching I've done against the G540 and wiring it to a VFD, it seems that the majority of the problems are with people getting voltage out.

My problem seems to be the opposite... I...

I'm interested to see your progress on this.
