Step multiplier for stepper drives?

[Zumba]

Any benefit of using one of the Gecko stepper drives with step multipliers running at full or half step? How does the performance compare to that of a G201/203V with Mach 3's kernel speed cranked up?

Currently only concerned about acceleration and top speed. Accuracy/resolution can be dealt with.

Is Mach3's 100Khz output not fast enough? That's the only reason to use a step multiplier. Not sure, but I think the performance would be similar. Some of Gecko's older step multipliers would sometimes lose a step on direction changes, but the newer ones don't have that problem.

Thanks Ger.

100kHz is plenty. I've got one setup with a 1" x 1.000 screw that's screaming at 2200IPM.

I was just curious as to whether fewer steps would equate to a smoother running or more reliable machine (spaced out TTL signal).
