Newly installed Duex5, BLTouch no longer working
-
Hardware:
RRF 3.3
DuetWifi 1.01
Duex5 0.10
BlTouch 1.1 or 1.2BLTouch servo is connected to PWM1 of the duex, and the z-probe pins have a 240ohm resistor across them. When the machine is turned on for the first time, it does 2 test probes with the BLTouch pin, then stays lit with the pin retracted. Z-probe in the sensor line of the DWC shows 1000 all the time. M401 and M402 commands no longer work (where they did before). Any ideas?

Remember that the self-test the BLTouch does on power up merely means it is getting power.
The control signal from the Duex to the BLTouch and/or the "data" signal from the BLTouch to the Duex can be wrong but the self-test will still complete.
Where on the Duex board is the BLTouch connected?
Thanks.

@fcwilt It's connected to PWM1 on the Duex board, but I just found that my White and Orange wires were swapped, so that has it fixed. Thanks for coming to my aid

Glad to hear it turned out to be a simple fix.
