** PID Tuning

Setup

Check the settings before PID-tuning

##Code:

M503

• M503 = the main command that triggers the PID Autotune calibration.

Results example:

function test() {
  console.log("notice the blank line before this function?");
}

---

Setup Hotend

Code:

M106 S255 

• M106 = the command for Set Fan Speed
• S255 = Speed, from 0 to 255. S255 provides 100% duty cycle; S128 produces 50%

Code:

M303 E-0 S220 C10 U1

• M303 is the main command that triggers the PID Autotune calibration.
• E-0 is the hotend that will be calibrated.
• S220 is the temperature of the hotend.
• C10 is the number of cycles. It’s a good idea to let the test run 5-15 times for the best results.
• U1 automatically replaces your existing heat bed PID values with the calibrated ones so you don’t have to do another step.

Code: M503

• M503 is the main command that triggers the PID Autotune calibration.

Setup Bed

Code: M303 E-1 S60 C10 U1

• M303 is the main command that triggers the PID Autotune calibration.
• E-1 is the number of the heat bed that will be calibrated.
• S60 is the temperature of the heat bed that needs to be tuned at which is 60° in this case.
• C10 is the number of cycles. It’s a good idea to let the test run 5-15 times for the best results.
• U1 automatically replaces your existing heat bed PID values with the calibrated ones so you don’t have to do another step.
