Anycubic Kobra2 heated bed with Duet3 6HC?
-
The original controller board output has a 2 wire 'control' signal to a separate power board to control the heated bed. It looks like I can just remove this extra board and wire the power and heatbed directly to the 6HC as they both operate on the 24v psu.
Here's a picture of the power section. Does it look correct to power it all directly from the duet board?

@bug2k22 How much current does that 24V heated bed draw? Are you sure that the Duet board can supply that amount?

I am not sure, the mosfet on the power board is a WSK220N04 if that is any help. I was asking in case anyone had experience of installing on one of these larger format printers, this has a print bed of 420x420mm.

@bug2k22 I'd be very cautious about using the on board MOSFET for that bed if you don't have any idea what current it can draw.

Yes, I'll just run it through the existing power distribution board for the heated bed until I get it on the bench and see how much current the bed can actually draw.

@bug2k22 if you have a decent multimeter, you can measure the resistance of the bed to work out the current draw.
