Anycubic Kobra 2 Printhead pcb & z probe?

[bug2k22]

Apologies for the multiple threads, I perhaps should have created a general install title to cover it all.

I'll attach couple of images of the print head pcb and a schematic I found online of the print head of this printer. Does it look like I could re-use the pcb and existing cable with a duet3 6hc? The extruder heater looks fine as it uses 2 sets of 3wires of the ribbon cable, but the others look to share ground and/or power signals.

Would it be better to just remove the pcb altogether and run new cables to the connectors? Would this z-probe attach directly to a 6hc? It looks like an inductive probe with 24v supply.

Thanks.

Be careful with anything that shares grounds and power. Duet switches things on the negative side, so shared negative won't work for heaters and fans, but shared positive might if they are the same voltage.

Have you considered substituting a 1LC toolboard instead?

I will probably end up swapping out the entire print head at some point, I've upgraded another printer to a duet with a revo hemera xs and it works well.
I was trying to keep the original print head stock if possible at the moment. I'll probably run a couple a new cables for the print head fans and see how the z probe functions, the schematic looks like a voltage divider is already on the existing board for this.

I think this board also has an accelerometer for the x axis as the under side of the print bed has another board for the y axis accelerometer, which I presume is not likely to work witha duet.

If I do upgrade the print head with a 1LC is it possible to use the accelerometer on this for the x axis and another separate accelerometer on the print bed for the y axis?

.. ooh I see there is now a duet3 scanning z probe which looks like it works much faster than the inductive or ir sensors.

Yes. Priod to the accelerometer being integrated into the toolboard itself you would have a separate board that you would attach to the appropriate axis for measurements and remove it afterwards.
