Multiple printers on one pi

Hi guys, hope someone can give me a hand.
Just setting up a bit of a print farm with one Prusa and two identical CR 10 on a raspberry pie 3. 
Just joined up the second CR 10 but software can’t see it as it says they’re both on the same coms port is there a way of changing this so it’s seen as two separate printers?


  • When 2 printers have same port id you need to use /dev/serial/by-path/... names. Here the usb port where it is connected defines the name so that is always unique but stops working when you switch port.
