How much power?
-
I'm trying to reorganise my power supply requirements following an imminent change to the heated bed (I'm going to a 230v bed).
All I need to know is what current the Duet board, hot-end, 4 stepper motors a few fans and LEDs will require. If someone can tell me that, or give me a reasonable estimate, I can add a percentage for good luck and work out the wattage I'll need.
Thanks in advance,

This should have all the info you need to work it out https://duet3d.com/wiki/Choosing_the_power_supply

Rats! I knew I'd seen the information somewhere!
If all else fails, RTFM (Read The *** Manual)
Thanks.

150w is plenty 120 might be enough

I've done the sums and it looks like a good-quality 150W PSU will cover all of my needs for a long while. A MeanWell PSU doesn't have a fan at that size, which is a bonus (I'm trying to reduce noise as well as improve efficiency).
Thanks again to all.

No worries. If you haven't noticed already, using Duet electronics, the steppers are really quite such that fan noise starts to become intrusive so a "fanless" PSU is a good move IMO.

I recently changed to 0.9 degree steppers for the X and Y motors on my CoreXY - that made a huge difference to the noise level. The Duet board drives them properly and quietly. Not just that they are quiet in themselves, but the assorted resonances I was getting from the frame and its panels have also gone completely.
