Re: Gecko 210s l- limited rapids

Jon, Thanks! Unfortunately the stepper motion control board went
out and I am having to wait for a repair. I am excited to adjust the
pot and see if I can maximize the speed. I don't think removing the
multiplier will help since I had the same trouble before installing
it and after installation doubled the speed. Perhaps when I get the
slow speed adjustment finished I can go back to 2000 steps per rev?
Would there be an advantage to having the microstep function given
that I don't need better than .001 inch resolution?
