The z offset wizard allows you to easily calibrate your printer's z offset to ensure that your nozzle is at a near-perfect print height.
The z probe wizard will require a piece of standard printer paper or a sticky note.
It is recommended to use a sticky note as you want your paper to be ~0.1mm thick.
Be sure to remove any filament from your printer and ensure that the nozzle of the tool head is clean and clear of debris.
Note: Currently, the SideKick printers are the only printers capable of running the z probe wizard.
Select the option "Move 0.1mm".
Place your paper/sticky note under the nozzle and lower the printer's nozzle until you feel a slight amount of resistance from the nozzle on the print paper when moving the paper/sticky note back and forth.
Once you feel some resistance, raise the nozzle up just a little bit and push the LCD button in to go back to the z offset wizard screen.
After running the z probe wizards, your z offset should be calibrated fairly well.
You may need to slightly adjust your z-offset depending on your configuration during a print as each filament and tool head may differ slightly in regards to how it performs during the first layer.
To do this during your printer's first layer navigate to the tune menu on your LCD and scroll down to z-offset. From here you can tune the offset up and down and the printer will adjust the first layer height as you adjust the settings.
Just remember to go back to the configuration menu and click store the settings once your printer is done again.
