My FOLGER TECH FT5 R2 printer has hotend that rises above a specific hotend temperature and doesnt even stop. It goes 5, 10 degree/sec and goes well above 265 even If target temperature is 200. My printer had THERMAL RUNAWAY ISSUES before and after replacing a bad thermistor with a new one, seems like I am not able to control the temperature.
I have read that controlling the BANG MAX temp helps, but how and where do I find this? Please tell me a short detailed steps and the software needed to import a Code to the firmware since I have no knowledge about the circuitry and zero coding experience. I am currently using SIMPLIFY3D for slicer. If you need more details let me know. Any kind of help is really appreciated.
