Hi All:
I've got a peculiar problem with my Mach 3 / Gecko 201 system that I recently got running. The Z axis is unreliable. When I rapid down or up I usually use the Page up/down keys. Something is wrong as occasionally, the Z axis will move in the opposite direction of the keys. I don't have closed loop so the axis position becomes wrong. I've tried many different settings like motor velocity and speed. Also tried setting the step line to active low and high. Nothing seems to make it perform reliably. I've got 201's with a limiting resistor. The motor is a SLo-Syn 300 oz./in. unit. Talked to Mariss when I set it up and he recommended the resistor and a capacitor between the power and common. Doesn't seem to be a heat related issue. Drive is running warm but certainly not hot. Perhaps a noise issue but the other axis run just fine.
Any suggestions?
Thanks
