Hi Nick,

It's a MightyBoard S3G, but there are differences with the Wanhao having an external card reader. I have now replaced the card reader to find that it was not the cause of the problem, so I am intending to ship the machine to the UK agent to get it sorted.

I have tried to connect the printer to my Win 7 computer with replicator G, but cannot get a suitable driver installed. Replicator G keeps saying the com port selected is already in use.
Amongst the Chinese instructions it says install the FDTI (FTDI?) driver, like wot Arduino uses, but it won't do it, and the installed driver for that com port is the windows default Usbser.

TBH, I am getting titsed with the problem and also the lack of info that makes sense on the Wanhao website.
