EXP1HCL "50.io1.out" PWM control issue
-
Hi!
I've successfully connected the following components:
- 1HCL EXP-BOARD (Duet EXP1HCL rev 1.0a or earlier firmware version 3.5.2, dated 2024-06-10 13:24:59)
- DUET 3 6HC (RepRapFirmware for Duet 3 MB6HC, version 3.4.5, hardware: Duet 3 MB6HC v1.02 or later, firmware date: 2022-11-30 19:35:23)
I've changed the CAN BUS address to 50 and configured two output pins as PWM outputs:
- M950 P6 C"50.io0.out"
- M950 P7 C"50.io1.out"
I am able to set the "50.io0.out" to any value using the following command, for example: M42 P6 S0.5.
However, I am unable to control the "50.io1.out" as a PWM pin and can only control it as a digital output (LOW or HIGH). According to the Duet documentation, it should be possible to configure the "50.io1.out" as either I2C or PWM out.
I've also attached a picture with the header removed to configure the pin as PWM out:
Any idea why this might be happening?

Your 6HC is on an older firmware than the expansion board. Update it to 3.5.2 to match.
