Power supply needs.. matching voltages

Newbie here trying to figure it all out...

If using a 24v power supply do all the electronics such as the heated bed/extruder/control board need to match those voltages?

I assume they do but just confirming my suspicions for the question..

Is the benefit of the 24v system faster heat times? any other advantages/disadvantages?

Thanks.

ampapa,

The electronics absolutely must match the voltage. That includes heaters and the control board, fans, etc.

24 volts has the advantage of faster heat-up times as well as the potential to make the motors a bit more responsive than 12V, although there's no guarantee you'll see that benefit. The main disadvantage is that you'll have to take extra care if your control board isn't designed for 24V (e.g. regular arduino mega is not).

yes everything needs to be rated for 24v.

"Is the benefit of the 24v system faster heat times?"

This depends on your bed, standard 12/24v PCB type beds are the same wattage at 12 or 24v, so heats up the same. Those that experience faster heat up normally have under powered 12v supplies or to thin wires to the heated bed.

It does mean you have more power, so you can have higher wattage beds


Steppers, they move faster and have more holding torque with higher voltages.
With higher voltage and lower currents thinner wires can be used.

Some have reported that some stepper drivers are nosier with higher voltages.

Thanks for the confirmation that matching voltages were a must.

Off to my next subject!
