Expansion Board

msugar

I recently changed the firmware version from 2.05 to 3.4.6 and I am having a lot of difficulties' getting the same outputs to trigger with the same commands. I am trying to trigger the FAN4 output using M42 P24 S1 and I am getting an error stating that the P value is too high. With firmware 2.05 this command would trigger correctly. I have made a new config file. Could this be because the new expansion board is not being recognized. How would I know if my duet board is recognizing the expansion board? How does the pin callout work with the new firmware? Is it different then what was used in firmware 2.05? I am using the duex5 expansion board and the main board is the duet 2 Wi-Fi.

Is there a number I can call to get support with this problem?

Here is the config file:

I was able to get the fans to trigger by using M950 instead of M42. How would I get the extruder heater to trigger? I have an LED strip connected to e0 so I just need to trigger it.

M950 is used to define the pin that M42 would control.
