THERMAL RUNAWAY - MK3S - PLA - 265C on first layer
I have a Prusa MK3S and I use the PEI Coated Sheet to print PLA.
I've found that in order to get the first layer to stick really well, every time I print, I crank up the nozzle to 265C for the first layer. After the first layer is down, I use tune and set it back to 215C. I arrived at this number through trial and error increasing +5C printing some very skinny tall things until I reached a reproducible success.
When I talk to others in the community, I get cringeworthy look like I'm doing something wrong. I've tried +10C on the bed, but it doesn't work as well as just bumping the nozzle temp.
This process gets me a perfect print every time that doesn't accidentally slip of the bed in the middle of a print.
The problem is every 2-4 prints, I get an error THERMAL RUNAWAY. I have to reset the print after this error.
There it is again. THERMAL RUNAWAY in the same place. The nozzle just stays on the bed making a big spot.
I think the best way to handle this is to immediately move the Z +20.
Does the error take into account that I manually increased the nozzle temp?
I was increasing the nozzle temp manually in the tune section. I just realized it's a setting in the slicer for first layer temp. I'm trying that now.
