IR-Sensor Problem with new DC42 1.19 Firmware
September 17, 2017 04:05PM
Hi there,

I updated my Firmware of the ReprapPro Ormerod today (0.60 to 1.19) and now the Z-Probe (poor old original IR-Sensor) is showing only values between about 300-420. In result the sensor will not work correctly as Endswitch for the X-Axis and also not for the Z-Axis! In my old configuration I had a threshold value of 500, like in the new firmware.
It looks to me that the values are too low! I have adjusted the threshold to a lower value, but the X-Axis endswitch function did not work anyways.

Hope someone will have an idea! I googled around now for about 1,5h but unforunately I found no solution.

Cheers, Frank

Possibly I used the wrong Firmware file for a newer duet board. Will check this this evening...

The wiring between the Z probe and Duet changed, around firmware 0.85 AFAIR. You need to move the blue wire along a few pins. The Ormerod 1 wiring instructions on the RepRapPro website now shown the correct connections I think.
