I need to be able to control, using PWM, 2 solid state relays that control the resistance of the bed to 230 AC and the resistance of the printing camera this also use 230 AC.

1. I think I need the extension board to have more PWM outputs but I don't know if this extension is only compatible with Duet 2 or also with Duet 2 Maestro

2. On a Duet 2 or Duet 2 master board, how many PWM pins are available?

3. Is it possible to reassign the pins in the firmware? For example, the output of the bed heater to me is not useful because I go to 230 AC, I need to assign a PWM of 5V DC to control the solid state relay.

I need to use NEMA 23 or 24 for my application, is it possible to use more industrial motor controllers, e.g. 8A?

As I understand it, in a simple RAMPS 1.4 could replace the drivers and connect in the high wiring of the high power controllers.

Thanks
