Is anybody running the latest version of Mach2 with spindle speed

If you are - does it work as expected??

If you are running an earlier version, please let me know which one
works for you!!

Steve,

I'm in the process of changing over to M2 and have just checked the
spindle Step / Dir circuit. Using a 100Mhz 'scope I can see that a
lot of pulses are being injected into the pulse train. I am using a
D-FF as a pre-scalar and it is very easy to see the injected steps,
they appear to be at maximum kernel speed.

Initially I was working at 35KHz, but I also checked at 25K and could
see that the pulse train frequently increases by about 25%.

One for Art to look at when he gets back.
