Hello, I just bought a rostock 301 printer.
I installed the driver CDM V2.12.00 driver; and the repetier-host V1.6.0
My device manager says that the USB post is Com3
I copied all the settings from the manual into the repieter-host & click 'connect'
The printer cannot be connected;
what can I do?

Re: Cannot connect printer
Have you tried changing the baud rate? I'm using Linux Mint 18.3 and the printer automatically connected at 250000 baud.
Just a thought... if the baud rate of the computer and main board don't match they won't connect. The version of Marlin I'm running (downloaded from Geeetech) has the baud rate set to 250000 in Configuration.h

Re: Cannot connect printer
Hello i had a similar problem, when i built my I3 pro B. According to the manual i try install the driver CDM V2.12.00, but this driver is for FTDI USB chip on GT2560. Unfortunately i found that my GT2560 use another USB convertor like CH340G. Try to see what you got for the chip on the GT2560 and download proper drivers.
