This seems also relevant.

Hi,
no that is not what I remeber but there is a some good stuff in that thread.

I was of the opinion that Mach4 did the spindle speed calculation and averaging but am now beginning to wonder if
I'm not mistaken, maybe this occurs in the motion controller.

I've raised a ticket on Poscope website.

HI,
I've just had a response from Andy, the tech guy at Warp9TD, the manufacturer of the ESS. The ESS handles the calculation and the averaging.....not Mach.
I presume the PoKeys works the same way. In which case the averaging is a feature of your motion controller and you are right to pursue PoLab about it.

I figuredit out in a very odd way.

Error gain value in PoKeys plugin setting was 256. I tried 64 and it worked. Then I restored it back to 256 and it worked too. Very weird. Must be a PoKeys bug.

Hi,

Attached is a screeshot of the ESS configuration plugin, the Spindle tab in particular, note the averaging time setting.

Hi Craig,

I solved the problem actually. Please see my post #14.

Thank you very much for your time and effort.
