When I call g31 for the probe the system will either not move at all or work perfectly. I thought it might be a loose connection or interference but I had it do a long move and tapped on the probe, yanked on all the wires, ect. Then I took the probe out of the equation. I ran a jumper from x210 straight to 0V. Same exact results. Then I got rid of the jumper and just set the probe to active low. This time I got either no movement, error saying probe was active, or worked great. When I call g31 z-10 for example, it seems like it always works the 3rd try, sometime on the first, sometimes on the 2nd, but always on the third.

I also tried it on x211 and x310 with the same exact results.

Am I missing something obvious? Is it possible I got a faulty board? Could something else plugged in to the board cause this? I am out of ideas so any help or suggestions for trouble shooting is appreciated. Is there a log or anything more than the diagnostic page to see if it tripping and why.

I have the UC300ETH with the UB1 BOB
