BTT Octopus V1.1 G34(Auto Z Align) Probe Failure

[CVRIV]

I bought 4 of these control boards to build 4 CoreXY machines and 3 of the 4 boards work just fine. The one control board will not G34(Auto Z Align). When I send the G34 code via my BTT TFT35 V2.0, it immediately tells me probing failure and aborts the G34. All of the machines are using a BLTouch connected to the dedicated BL Touch port. Here's the thing... the BLTouch works just fine when homing and leveling the bed. All of the machines are absolutely identical, same firmware and everything. I just don't understand why this one board will not do a G34. I don't want to buy a new board if I don't have too.

Any ideas would be greatly appreciated. e
