I am using the OB Control with BlackBox controller. Drivers are updated and current version of OB Control installed on my Acer Iconia W700p Windows Tablet. Today I have been trying to run a surfacing job and I started getting the Hard Limit errors and now I just noticed that OB Control display for all axis is way off and the UI is off too probably because the giant numbers displayed. I have no idea where to trouble shoot. I am running CNC4newbie New Carve 1045 with a Makita RT701c router. I also have a POWERTEC DC5370 1hp dust collector running. I am guessing this is EMI but I have no idea and not sure how to go about troubleshooting. Like I said it has happened before intermittently but today every time I start a job it gets part way through and then it just throws the error or the OB Control software bugs out.
