So I had the E3D revo for a while now. First time ever I got a thermal runaway during a print last week.
Now during preheating it fluctuates a bit, when heating to 240 it can go from 238 up to 260 or even 280 in seconds and then drop back again. When the preheating is done and the print starts it looks like it’s stable, from 239 to 241 in first layer (printing PETG) and then around 250.
What cause this? Is it dangerous to leave the printer printing like this?
RE: Revo temperature
PETG print finished fine yesterday.
PLA-print today, 3hrs into print filament got jammed.
