Now that's what I call a recommendation.

Does anyone know if I purchase Mach 3 and pay a little extra later on and move over to Mach 4?

Sorry, I know I've asked a lot here. Thanks to anyone that helps. Tweakie and RICH have been great to me, but I don't want to look a gift horse in the mouth.
The best cure for this is to remove update KB3035583 and then untick the 'Give me recommended updates' under change settings. No more nagging until Microsoft force everybody onto there latest pay as you go scheme.
Do you think reducing the microstepping on the Z Axis driver so it takes less pulses to move 1" will have any impact on the results?
The pulse width is set to 5us for step/dir on all axis. The TI driver has a minimum pulse width of 1.9us so this should be OK, right?
I was running the driver test and checking all frequencies. Even up to 100kHz it reports the system is OK. I noticed that up to 65kHz the CPU usage is less than 5% but 100kHz is ~50% but I don't see any reason to push it that high. When I look at Max Variation I see mostly repeatable spikes and values of 15us or 23us. This doesn't seem to change when I change the frequency but occasionally I see nice smooth line aith maybe variations of 5-8us. Is ~20us variation something to worry about? Should I break out the scope and see what the step pulses actually look like?
