Repetier server 2 usb port

Ray3D

Hello.
hope someone can help
I’ve been using repetier server for a couple years and works great, no issues

I got my friend in to it and he has 2 printers installed without issues
he tried to install a anycubic 4 max pro v2
when he plugs it in on the usb list up comes 2 new ports to choose from, unplug it the two disappears
he tried each port and there’s no communication.

Any idea what the issue is….
he does have a different anycubic printer which works fine
we are using a raspberry Pi with the latest version of Repetier server

thanks

2 Ports means serial/by-id and serial/by-path appear? That is normal and ok.

Best is to select in install wizard autodetect on baudrate/dtr/rts so server tries all combinations. I assume it is using marlin? Some boards only communicate with one rts/drt combination and of course baud rate must match, also nearly all use 115200 or 250000.
