[BUG] "Heating disabled due to inactivity" during active printing #3574

Describe the bug I was printing a piece which I had accidentally inserted a color change, so I didn't expect it. By the time I realized it was waiting for a filament reload, it had disabled the nozzle heater. I reloaded the filament and it reheated the nozzle as expected and continued the print.

However, exactly 30 minutes later, it disabled the nozzle and the bed heater in the middle of the print, showing "Heating disabled due to 30 minutes of inactivity" and continued printing without extrusion.

How to reproduce

  1. Print a GCODE that includes an M600 color change at least 30 minutes before the end.
  2. When the color change hits and the filament unloads, wait 30 minutes until the nozzle heater is disabled.
  3. Reload the filament and wait for it to heat the nozzle back up.
  4. Continue the print
  5. 30 minutes later, the nozzle and bed heating will be disabled and will stop extruding

Expected behavior Inactivity timer should never trigger during an active print.
