which rail to use for LEDs?
I have got the black power supply and would like to attach an 24V RGBW LED strip to light the printer up. (To be exactly, I want to attach the RGBW shelly and a RGBW strip to the shelly...)
I thought it would be a good idea to use the rail that has the lowest load on it.
But I dont know which one it is and how to find out?
Any ideas?

Well after looking at the manual - Prusa does not seem to care which rail is used for what.
As far as I know this may be a single rail PSU internally - and probably is.
The Einsy board has six terminals; 4 for the PSU and the rightmost two for the heat bed.
I think I arbitrarily said the middle pair provide power to the right pair, gated by the Einsy.
So I would track the middle cable back to the PSU - and use that one. Not that I think it matters.
I will retreat now...

I used the least critical one. The Heatbed one. I don't care much about noise on the heater.
RE: which rail to use for LEDs?
sounds good, but I yet wasn't able through googleing or looking at manuals, to find out which one that is ... 🙂
Can you help me out?

if its single rail it wont matter, but thank you, I gonna track that cable down and use it. 🙂
