I've got a probe setup that does x,y,z probing and connected it up to a pmdx 424. On the machine diagnostics I see the probe signal working just fine but when I go to use it I periodically (more often that not) get a message saying "Can't transition from MDI RUNNING to STOP". The probing I'm using is from the Mach4 4.2.0.3124 of the touch menu on the main screen form. I figured that since the 424 is involved in probing I'd ask here first.
