Using a CNCRouterParts PRO4848, I recently converted from the standard Smoothstepper/Mach3 to UCCNC and the UC300ETH-LPT5 with UCCNC Screenset 2017. I'm using the probing macro supplied in this thread...

Conversion was fairly uneventful and everything initially work very well. A few weeks ago, I was measuring tool length using "Auto Zero Initialize" and the tool started moving upwards. I checked all the setting and confirmed that nothing changed. Restarted UCCNC with no change. Shut down and restarted everything and still had the same problem. I needed to cut a project , so I just set the Z-workpiece manually. Everything cut fine, so I'm sure it's strictly a probing based issue. When I tried again a few days later, probing worked as expected. Well it happened again yesterday and I'm scratching my head. Any ideas?
