Re: Gecko 210s l- limited rapids

Found the nema 42 jumper and connected to find now I have 40ipm
rapids instead of 20. That is better but why not faster. I have
the multiplexer set at 200 steps per rev. Would going back to 2000
steps per rev speed me up? I still have to do the pot adjustment at
slow speed, would that make that much difference?\

thanks
