12 e 24 volt
-
Good morning, I would like to install a 24 VOLT Hotend, so I have to power the duet wifi card at 24 VOLT, is this correct? I wonder what other components will need to be changed? Can I use 5 or V 24 no 12V fans OK? Can I use 5V stepper motors OK? Do the optional 5 and 3 volt pins remain as such OK? IS coret?

The red and yellow 5V/3.3V stay as indicated. Everything orange will switch to 24V/VIN. You would need to switch the bed heater. Fan outputs can be set to use either VIN or 5V via the FAN JUMPER SELECT header (one setting for all fan headers on the Duet 2 boards).
To summarize: If you switch VIN from 12V to 24V you will need to switch out the bed and hotend heater. If your fan jumper select is set to VIN, you will need to switch out the fans as well.
I am not sure I understand the question about the motors, but if you use typical bipolar NEMA17s, they will run both on 12V or 24V (but you will be able to reach higher speeds with 24V because back EMF can go higher before it overcomes the power supply). Note that the rated voltage on stepper technical data sheets do not need to match voltage provided via the stepper drivers used on Duet boards (or elsewhere).

@oliof thank you, everything is very clear now, A CLARIFICATION because on the diagram the engines are not in orange wine at 12 or 24, but there is only one red 5v perhaps a color used improperly also earth black at least according to the list legend. it's just a question also because the integrated stepper drivers hold 30 volts.

@luca-Massimiliano the colors for the steppers reflect the typical colors of the wires on steppers. As such, the red and black do not refer to voltage and gnd. Unfortunately the allocation of colors to stepper phases is not standardized, so you will need to check phase pairs (by measuring resistance for example) to ensure stepper wiring is correct.
