If I set temperature say 220 °C, printer heats up to it and it only varies +/- 0.5 °C under non operating condition. But if I start a print, there's a shift of +/- 15 °C.

I've already auto tuned PID parameters and Whenwhen I run M503, the printer shows the updated PID values.

What could be the reason?

  • Firmware used: Marlin
