@Zerocool1703 said in Duet3 6HC claims SBC is connected when it's not!:

M115 also works which I would not expect if the SD card wasn't properly connected, right?

M115 will always work. To test whether an SD card is present and was read at startup, send M39 or M503.

@Zerocool1703 said in Connecting multiple heated beds to Duet 3 6HC:

But I have also read that SSRs can't really handle PWM signals, because it's at too high a frequency and you should rather use a "bang-bang" mode?

You can still use PWM you just have to use a low frequency.

Here is my setting:

M950 H0 C"bedheat" T0 Q10 ; create bed heater output on bedheat and map it to sensor 0

Notice the Q10 which specifies the frequency - it works fine with my SSRs.
