Printers trading spots on server

I am running a Sovol SV06 and a Sovol SV06 Plus on a Pi 4B.  If I turn on the SV06 Plus before the SV06 it will grab the SV06 connection and profile also if I turn on the SV06 first they get their correct connections unless I turn off the SV06 then the Plus will stop what it is doing and switch over to the SV06 spot.  It is very confusing and aggravating if I have a print running on the Plus when it does this as the print will fail.  How can I fix this?


  • It depends on the port names assigned by linux. The one you have choosen depend on connection order. Slect instead ports starting with /dev/serial/by-path so it is important which port they are connected to.
