Correct way to power 1LC?
-
Hi,
What's the "correct" way to power the 1LC -- straight from the psu or can I use the OUT 0 on my 6HC?
TBH I'm a little confused what the purpose of those OUT 0 are are they are listed as both in- and outputs.
If someone could explain that it would be great

@Reine Out0 is normally used for a high-current bed heater.
The reason it's listed as an input and an output is that YOU get to select and provide the correct voltage for your bed and it can be different than the voltage used to power the Duet.
So, you "input" voltage on one pair of terminals and you "output" voltage on the other pair of terminals that connect to the bed heater.
Out0 is called a "switched-ground" output rather than a "switched power" output, so you cannot use it to power your 1LC.
You can read a LOT more in the Duet wiring documentation.
THIS links to the Duet3 6HC bed heater part.(OK, it might just barely be possible to power a 1LC from out0, but there's a lot of things to consider re: grounds, and since you're asking, I think you're slightly less experienced than an expert, and you could get into a lot of confusing issues if you don't completely understand everything.)
So, power your 1LC by applying between 12 and 32 Volts to the power connector and you'll be cool.

@alankilian thank you for replying -- sounds like my best option is to hook the 1LC up the the same PSU as the 6HC then
So with the v1.02 I could run steppers at 48v and power the bed from the Duet at 24v? That's neat!
-
@Reine FYI - I believe if you power the 1.02 6HC with 48v, the other outs (for hotends/fans/etc) will also be at 48v. For outs4-9 you can set a jumper for 12v with max 800ma total across all or provide external power (eg from your 24v PSU to a pin on the 6HC) . Outs1-3 will still be at VIN though.

OUT0 has its own power supply input and it can be a different voltage than the rest of the board.
- I don't think anything runs at 48 Volts though. +32 is the max as far as the documentation says.

@alankilian the 3HC v1.02 and 6HC v1.02 can accept up to 48v as an input voltage

HEY!!! Look at that.
I usually google, get to the obsolete documentation which has a link to the new documentation and sometimes that's still old.
This is good to know, thanks.
