Re: Gecko Bridgeport saga improving

Keith, for the money you spent on CamSoft and new motors, I would
demand more than 75ipm. My BOSS 6 had rapids of 110-120ipm with the
POS factory control. I know your original motors should be capable of
the same, and I would hope your new motors are capable of even more.
I think the geckos should be able to get you somewhere near 120ipm.
You really need to get a scope on the step/dir lines to the geckos
and see what's going on. How fast will the machine go using the
standalone pulse generator?
