Hi I am running a Black Box, Open Builds Interface and the XYZ Probe Plus. I Home the machine and it works as it should work, No problems there. Then I jog out to the work piece. Center the bit to the hole of the xyz probe. Load the xyz probe file. Check the probe plate and see that it is working ( Green Light). Hit ok. The machine checks the Z axis and lights the green lights and that is when I get an Error message. Error 2 Numeric value format is not valid or missing an expected value. I hit Cancel and if I jog the Z axis it raises up till it hits the Limit Switch. Then I cancel out of that and Home the machine and it goes home. Glad I got Limit switches and hard Limits on because I don't think it would have stopped. Since I'm fairly new to all this I don't know why it's doing that nor how to fix it. I checked all the wires and I didn't see anything wrong.
