Single Extruder
- Connect Gigabot's power and USB cables.
- Using Pronterface connect to Gigabot.
- Turn on the head fan by typing M106 S255 command in the lower right corner of Pronterface.
- Ensure the hot end temperature is below 100C.
- In Pronterface type into the data entry box at the lower right corner:
- For GB2 use “M303 S200”
- For GB3 Left Extruder use “M303 E0 S200”
This will start the PID auto-tune function in the Marlin Firmware. The hot end will cycle the heat up and down for a couple minutes until displaying the message: "PID Autotune Complete". Write down the last set of output values given.
- Classic PID
- Kp: 50.03
- Ki: 1.98
- Kd: 150.98
Adjusting the firmware
- 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 H1 P(your Kp value) I(your Ki value) D(your Kd value)".
- It should look like this using the example above: "M301 H1 P50.03 I1.98 D150.98" This will TEMPORARILY change the current settings for the temperature controller.
- In Pronterface type into the data entry box at the lower right corner: "M500" and press Enter. This will make changes permanent.
- In Pronterface: Set hot-end temperature to 200C and watch the temperature overshoot the target temp slightly, undershoot slightly and then settles onto the target temp within 1-2 deg.
Dual Extruder
- Connect Gigabot's power and USB cables.
- Using Pronterface connect to Gigabot.
- Turn on the head fan by typing M106 S255 command in the lower right corner of Pronterface.
- Ensure the hot end temperature is below 100C.
- In Pronterface type into the data entry box at the lower right corner:
- For GB3 Left Extruder use “M303 E0 S200”
- For GB3 Right Extruder use “M303 E1 S200”
This will start the PID auto-tune function in the Marlin Firmware. The hot end will cycle the heat up and down for a couple minutes until displaying the message: "PID Autotune Complete". Write down the last set of output values given.
- Classic PID
- Kp: 50.03
- Ki: 1.98
- Kd: 150.98
Adjusting the firmware
- 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:
Left Extruder "M301 H1 P(your Kp value) I(your Ki value) D(your Kd value)" Right Extruder "M301 H2 P(your Kp value) I(your Ki value) D(your Kd value)"
- It should look like this using the example above: "M301 H1 P50.03 I1.98 D150.98" This will TEMPORARILY change the current settings for the temperature controller.
- In Pronterface type into the data entry box at the lower right corner: "M500" This will make changes permanent.
- In Pronterface: Set hot-end temperature to 200C and watch the temp overshoot the target slightly, undershoot slightly and then settles onto the target temp within 1-2 deg.
