Kirk, This seems to me to be purely a problem related to double-step/stepconf. Everything runs fine with my old configs. It is only when I use the stepconf generated configs (now modified) that the problem shows up. I am trying to identify what stepconf/double-step does that will allow 2 axii with the same configuration to have one run and one not. Old configs -- With the acceleration set at 30, I can reach 90ipm on both axii (x and Y). With acceleration set at 20, I can reach 120ipm on both axii. So for purpose of trying to figure out stepconf, I have set the acceleration at 20 and the max-vel at 90ipm (1.5ips). With the new configs Y performs exactly the same way but x just sits there. Actually when I am trying to jog the x, if I hold the jog button down continuously x will sometimes make a single step (maybe once every 15 or twenty seconds).
