Having some problems with making 3D items. I can make small items(ie. generic items, mostly small flat items) with no problems, but everytime i try to make a large item like http://www.thingiverse.com/thing:1150625/#files, the plastic keeps seperating from the plate near the front end. I wipe the plate down with Acetone after every use. Is the plate not hot enough? Couldn't find a way to change heat settings in Creator Pro - Replicator 040.

Also i read that its easier to to print from the SD card than over the USB wire. How do I move the file to the SD card? The Creator Pro can connect to the printer but the printer doesn't show up on my PC.

Apologies for what i'm sure are extremly noob questions.
