Stratasys recommends a chamber temp of 70-90, I put 90 as an upper limit to what I'd be hitting. Does your Wanhao use an E3DV6? I don't believe that my stepper motors can handle that kind of heat with the kind of aggressive acceleration settings that I will be using on top of that. I'm honestly surprised to hear that you can run your printer with a 70C heated chamber and not have to cool your stepper motors at all. You don't get skipped steps? http://forum.e3d-online.com/viewtopi...7adadcedc8181d

This guy's steppers shoot up to 120C without watercooling in his heated chamber so something isn't adding up. Also doesn't Stratasys use a massive air duct to force air in and out?
