hi I have an invision XT 3D Modeler that I can't get working right. I unfortunately don't have an owners manual for the machine. Every time I go to do a test print the printer will go through the 4 phases and when it gets to phase 1 it times out. The error code that it reads is RT_ERROR: Preheat1 Temp build Temperature Timeout. Any help with this issue would be appreciated greatly.
