I tried a couple searches to see if anyone else was experiencing the same problem, and my initial results are pretty sparse. The printer starts like normal, but for some reason around 170 degrees, it decides that it's warm enough, even when the readout clearly shows that it's under temp. this results in the first layers of the print refusing to stick. We're using blue tape as the base, (which isn't a problem on the printrbot we've used). after the printer reaches temp everything seems to stick fine, but by then the foundation has pulled up, causing all sorts of problems.
Another problem we encountered (different print) was that any circles the printer was supposed to complete left a gap. These are both new problems, and the printer has worked before just fine.
