Re: Micro Steps question please...
In terms of positioning, its not much point going past 10x but higher values will help improve smoothness. But also the maximum frequency your controller can operate will limit what you can get away with.
I can get away with 25x micro stepping but I am using hardware stepgens (linuxcnc and Mesa 7i76e ehternet card) . Its a while now since I worked it out but I think I was up around 90 kHz at max speed but a parallel port might be limited at 50 kHz.
And I'm in Brisbane
