How do I find Marlin PID values?

How do I find Marlin PID values?

Finding Hotend PID Values Marlin has a built-in tool to allow users to easily come up with the correct PID values for their printers. This command is M303 followed by the hotend number (E0, E1, etc.), S (temperature), and C (number of iterations to run).

What is a PID tune?

PID tuning refers to the parameters adjustment of a proportional-integral-derivative control algorithm used in most repraps for hot ends and heated beds. PID needs to have a P, I and D value defined to control the nozzle temperature.

How do I run a PID tune?

Fortunately, the printer has an automatic way of tuning these values.

  1. Step 1 Open G-Code Terminal. Open the G-Code Terminal in MatterControl.
  2. Step 2 Run Auto-tuning. The M303 command runs the PID tuning.
  3. Step 3 Set PID Values. Each firmware has different requirements for saving PID values.
  4. Step 4 Save settings to EEPROM.

What does PID tuning do on a Marlin printer?

It controls how your printer handles temperature adjustments to your hotend and heated bed. Having these parameters calibrated will ensure you have more consistent temperatures at your hotend and heated bed which can help improve print quality. Marlin no longer controls heat by simply turning the heater on and off to make adjustments.

What is the hotend number for PID tuning?

This command is M303 followed by the hotend number (E0, E1, etc.), S (temperature), and C (number of iterations to run). *Please make sure your part cooling fan is set to 100% (M106 S255) before continuing for best results

How many cycles do I need to run PID autotune?

At least 3 cycles are required. Default 5. Toggle PID debug output on / off (and take no further action). (Requires PID_DEBUG) Hotend index (-1 for heated bed). Default 0. Use PID result. (Otherwise just print it out.)

Is there a thermal auto tuner for PID?
