Problem Connecting 2 printers at the same time on RaspberryPi
Hi,
I have two printers and I had to change one of the printers mainboard recently. After the change I can not connect to both printers at the same time, anymore.
It works fine when I turn off one of them. But as soon as I run both only one is left (the SKR).
I tried to setup as a new printer but even then I just have two that mirror each other.
One of the boards is a MKS Robin Nano 1.1. The other one is a BTT SKR v.3 board.
Server Hardware RasberryPi 3b
Firmware: Both Marlin 2.1.x
Robin: Serial ports 3 and 1
SKR: 1, -1 and 3
Help is appreciated.

If there is just one and in by-path you see two you must select port by path instead to select the right one.
The Nano is still switched on but has no connection at that time.
I tried moving both and only one to path but still same result.
Btw. the Nano disconnects even when I switch the SKR on while it is in deactivated state.
Are there undervoltage warnings in the bolt menu?
If you switch to the console of the non working printer do you see any usefull messages?
Some more details:
When I connect the Nano first and then turn on the SKR. The connection looks to be alive.
BUT!! I am able to give one last command. After that the connection stops. The link symbol is still green but no reaction.
The Ip adresses that I redacted are my Ststic IP adress.. Dont know why it gets these after the disconnect.

Mesg:11:06:55.793: Connection started
unplugged SKR and Nano USB plugged back in the Nano USB cable:
It doesn't work ( /dev/serial/by-path/platform-fd500000.pcie-pci-0000:01:00.0-usb-0:1.2:1.0-port0 for the Nano)
Also if I connect one as path the other one as port. No success.
Meanwhile I tried to connect them to my laptop and I got the same result.
You might want to try different dtr/rts settings in case it uses hardware flow control.
Actually Inam currently running one server on the pi with the nano and another server on the laptop with the skr
