Step 1.

First, make sure the printing nozzle has no filament hanging from the bottom of it. You can simply break this off with the included pliers.

Step 2.

On the touchscreen, navigate through 'Maintain' > 'Calibration' > 'Normal Mode', and allow the printer to setup for calibration.

Step 3.

Once the calibration screen has appeared, slide a piece of folded A4 paper onto the platform, under the print head. (If the paper does not fit, raise the print head by using the '+' sign on screen)

Step 4.

Next up, click the '-' icon on screen once and wiggle the paper. Initially the paper should move freely under the nozzle. Repeat this process, until you feel a slight amount of friction, indicating that the nozzle, paper and platform are now touching. Then tap 'Next' on screen.

Note: On Adventurer 4 you can then repeat this process for the other 9 points on the bed. On Adventurer 4 Pro, it will automatically complete the remaining points on the bed.
