Is there a program that I can be able to stop the print thats being made with a computer hooked in? I just got a camera set up so I can view it from anywhere, but I'm not sure how I could stop it if something was not going right. I have only printed via SD so far, I just tried to install Makerware 2.4 on that computer but it keeps giving me a error, it's a older one I just took out for this.
