Record your current Extruder Steps Per Unit
For users with the Graphical LCD controller use the GLCD controller to view your current extruder steps per unit:
- Navigate to: Control > Motion > Esteps/mm
- Record the current value and skip the below section. Proceed to the next step.
If your 3D printer is not equipped with a Graphical LCD controller pull your current Extruder steps per unit from your Test Acceptance Record. The value will be labeled "E0".
If you do not have your Test Acceptance Record contact our support team by sending an email to Support@LulzBot.com. Include your 3D printer serial number (found on the back of the printer at the base of the electronics enclosure) and request your Esteps.

Once you select the firmware .hex file, the firmware will be flashed onto your LulzBot 3D printer.
Update your Extruder Steps Per Unit
Using your Graphical LCD controller update your Esteps by navigating to: Control (or Configuration) >Motion > Esteps/mm. Adjust the value there by using the control knob.
Save the value by navigating back through the menu and select Store Memory.
If you do not have a Graphical LCD controller you can send a command through Cura, by loading a model, pressing Print and sending the M92 command: M92 EXXX with the "XXX" replaced with your extruder steps per unit saved in the first step. Follow that with the command to save the settings: M500.
