With the extruder cooled off:
In Pronterface type into the data entry box at the lower right corner “M303 S195”. This will start the PID auto-tune function in the Marlin Firmware. It will cycle the heat up and down for a couple minutes until displaying the message: PID Autotune Complete
Read the last set of output values given
- Classic PID
- Kp: 50.03
- Ki: 1.98
- Kd: 150.98
In Pronterface disconnect from Gigabot, Close Pronterface, Restart Pronterface
Connect to Gigabot
In Pronterface type into the data entry box at the lower right corner:
M301 P(your Kp value) I(your Ki value) D(your Kd value)
It should look like this using the example above: M301 P50.03 I1.98 D150.98
This will change the current settings for the temperature controller.
In Pronterface: Set hot-end temperature to 195C and watch that it comes up to temp, overshoot the target temp slightly, undershoot temp slightly and then settles onto the target temp within 1-2 deg.
These kp, ki and kd values (M301 P50.03 I1.98 D150.98) should be copied and pasted into the start g-code in Slic3r
Slic3r -> Printer Settings -> Custom G-code -> Start G-code
or
Simplify3D -> fff settings -> Scripts -> Start G-Code
