### Basic Information:

Ender 3S1  
CR4NS200141C13 board  
Raspberry Pi 3B+

[klippy(2).log](https://klipper.discourse.group/uploads/short-url/tZnquNAKJmgv1aBADyj6dbnAS1O.log) (59.7 KB)

I am trying to set up several klipper/moonraker instances to connect 2 oder 4 printers to one Rasp Pi, but I don’t get it work.  
Is the problem that I try to expand the system from one instance (works perfect) to more instances - is it recommended to start a new installation on a new system instead?  
Is the performance of one Rasp Pi 3+ enough for 2 or even 3S1 printers?  
To use my old configuration: I assume, just the printer.cfg has to be transferred to the new instances?

Grateful for any help - or a basic description to set up multiple instances.

Doing it manually is quite involved.  
I recommend using KIAUH. The only challenge is, that once you have installed one instance, KIAUH does not offer to add additional ones (at least this was the case last time I checked)  
So, the probably easiest way is backing up your config folder and start over with KIAUH.

Always keep in mind: If you are running 4 prints and the Pi crashes for what reason ever, all prints are gone.
