I would get to a very basic setup then add a feature or two at a time, test, rinse, repeat, until it breaks, then back up one step. Disable things like backlash & leadscrew correction, as I think they could have an effect on counting.
Some of the signals in your HAL example are quite different than what i have in my config. Did things change a lot in 2.8? I don't have anything with "joint" in the name. Do have a bunch with "axis" in the name. Ray --J. Ray Mitchell Jr. jrmitche...@gmail.com The dogmas of the quiet past, are inadequate to the stormy present.
