The components installed on your printer rely on firmware configuration. To facilitate for components sourced from third-party vendors firmware version 4.3.3 introduced an "Experimental menu". Because different hardware has different specifications, the firmware is now capable of adjusting the defining parameters of some components.
To activate the experimental menu, navigate to LCD menu -> Settings and scroll down to HW Setup without selecting it with a short-press (left picture). Instead, Hold the knob for 2-3 seconds and after a “click” sound, the Experimental menu will appear (right picture).
|Long-press this option.
|After holding 2-3 seconds this menu will appear.
Save and return: Saves the current values and returns to the previous screen.
After the correct settings are changed, select Save and return. The printer will ask you whether you want to save the changes and reboot the printer. On reboot, your printer will have the new settings for your custom extruder. This will ensure, that even with adjusted parameters the printer will be still able to perform First Layer Calibration, Live Adjust Z and, of course, print.
