I am having a issue with Mach4 is skipping over some G Code moves on files that work perfectly in Mach3, I am using the HiCON controller. Another member informed me he encountered simular problem and corrected it by updating the firmware in the HiCON control, so I updated the firmware and now I cannot arm the HiCON, in Mach4 message screen getting: [ Error Unable to ARM Drive (code 355) ]. Anyone have ideas on how to get the control to arm?? Tried to go back to previous firmware but still cannot arm the HiCON. Did not have any problems with arming the HiCON before the firmware update.
