IRProbe - always in digital mode

Doowrednu · 13 Mar 2017, 18:37

I am fitting a new IRProbe and it always turns on in digital mode (2 flashes) - i've checked all the wiring with continuity tester at both ends of cable but cannot find a problem - any other troubleshooting tips ?

Thanks

Do you have it specified in your config.g using M558 P1 which sets analogue.

How have you connected it to the Duet, and how have you configured it in your M558 command in config.g?

I cut the ends off a shielded USB cable, crimped three of the four cores and connected to the Z Probe socket on Duet Wifi

Is the probe working apart from running in digital mode? Are you sure you are using the correct 3 pins of the 4 pin Z probe connector?

Yes was working in digital mode - I found the problem - a second M558 in config by mistake -thank you for your help
