Da Vinci pro
Installed the host but can't connect to the prnter. Should I be able to without doing or installing anything else. It tries searching the com port that the printer is attached to, Com3 is a USB port.
If windows knows the serial driver it should work depending on firmware the Da Vinci runs. I know some users changed firmware to repetier variant (not sure if also for pro) and I think one reason might be being able to communicate, but I don't know for sure. You might google if it original firmware is compatible with repetier-host.
All you need is correct baud rate and select autodetect protocol or ascii.
