Hi,
I'm trying to connect 3 SSRs to control heaters to a duet 2 ethernet with an Expansion Header Breakout Board. I managed to get H0 and H1 working, but H2 isn't. When I switch the heater on through DWC no voltage is measured at the clamps on E1. I'll attach the config below, I think it should be correct.
Could this just be a defective board? Is there a way to use a PWM output from one of the fans to control the SSR instead of E1?
Best regards
Patrick
