Help with Prusa i3 / Repetier
About a year ago I purchased a reprap Prusa i3 3D printer kit off of eBay. After I was went through a lengthy configuration then calibration process, the printer worked great. Unfortunately, the laptop that I had originally set the printer up on died. After replacing a hard drive and rebuilding the computer, I now need to re-configure repetier.
I downloaded and installed the latest version of the application.
I am able to xyz.STL file no problem. Where I am getting stuck is connecting my laptop running Windows 7 to the printer. I have it connected via USB.
When I click on 'connect', I get 'Serial com error:system.io.ports........... error
Under printer settings I have 'connector' as serial connection (the other drop down says says virtual printer). Under port, the only drop-down is 'COM3'.
I am definitely missing something that is probably very apparent to an experienced user. Any help would be greatly appreciated.
