Unsolved Wiring 2 heated bed
-
Hi all,
I want to know if it's possible to connect and control two différents heated bed with duet 3
On my 1000/1000 printer I want make 2 500/1000 heated bed and control each bed
It's possible?

There is only 1 high current output (out0) so you could connect one directly to that one, to connect the second, you would need to use an external mosfet or DC ssr to connect the second and use one of the low current outputs to switch the external device.
Does that make sense?

@Phaedrux I have 2 ssr no problem for that and duet firmware can contrôle the two bed separately?

Controlling multiple beds will be a little more complicated. Typically heater 0 is the bed and heater 1+ is for an extruder and maybe a chamber heater. The slicers are only able to control the bed and extruder temp usually. So you'd have to control the second bed heater more manually. Perhaps treating it as a chamber heater, which some slicers can control.
I don't know what your printer is like or how it's used though, so I can't really give any specific recommendations.
