I have just completed my Mendel which uses the Techzone gen3 remix electronics. I have been unable to get the host software on my WinXP workstation to connect to the printer. The Arduino IDE connects just fine and uploads the firmware but I get problems with both Repsnapper and Pronterface when I try to connect.
From Pronterface I get a "cannot open port COM1, access is denied" message and from Repsnapper I get a "connection attempt timed out" message. I have tried using both COM1 and COM3 with the same results.
I had to manually load the driver for the USB/TTY interface board and I noticed that there were two of them. One was a VCP driver (sets up a virtual com port) and the other was a D2XX driver (allows direct connection using a dll). I used the VCP driver but perhaps I should have used the other one.
Can anyone clarify this for me? I had all 3 axis moving correctly with the Reprap Host software on my old Linux machine but I never had to load drivers for it. They were already present.

Always use the right tool for the job, and the right tool for every job is a hammer.
Note - the above is not true but some days it feels like it's true.
