I think I've identified the location of the problem, I just need some hints on how to get over it.
Watching the component pins I can see the position_cmd change when I issue an M6 Tx command, but there is no stepper activity. It seems to me that the problem is related to this being done on a BBB with PRU ... The original toolchanger hal file has: net apos-cmd toolchanger.position.cmd => stepgen.3.position-cmd I thought all I needed to do was update that to hpg.stepgen.03.position-cmd and all would be good but the Xylotex.hal file I'm editing doesn't have a hpg.stepgen.03.position-cmd So the question is what am I supposed to link to? There are a few I can try but its a bit painful doing it trial and error. help here is appreciated.
