Hotend Not Maintaining Temperature - PID Autotuning

The video tutorial addresses issues with maintaining specific temperatures on a 3D printer's hotend, particularly the CR 10 model. It emphasizes the importance of setting unique PID values for different filaments to achieve optimal print quality. The tutorial provides step-by-step instructions on running a PID auto tune using commands in a terminal and storing these values on the printer. It also highlights the need to adjust PID settings when using an active cooling fan and offers tips for ensuring consistent temperature maintenance. The video concludes with a promise of future tutorials and a giveaway announcement.

What values are needed for running a print at 235 degrees without an active cooling fan?

Why is it important to set your PID values in the start gcode for each unique material profile?
