1:  I can print well for a few days then out of the blue my extruder temp fluctuates wildly.  The temp is set at 210 but it goes up to 230+ at times then does nose dive and won't recover.  I have tried reinstalling, and turning off and restarting.

2:  after slicing and temps say they are good it has started to show a dry run in the at a very rapid pace.  I have made sure that I did not have dry run selected.
