Ok, I verified the pin and changed the line in the HAL to: net mpg_count hm2_5i25.0.7i76.0.0.enc0.count => axis.0.jog-counts axis.2.jog-counts axis.1.jog-counts
With halcmd I can show hm2_5i25.0.7i76.0.0.enc0.count and see it go to 1 briefly when spinning the MPG, so it looks like the signal is getting in ok but I'm still not getting any axis movement. ------Original Mail------ From: "Peter C.
