NOTE: Manual nozzle height should only be used if your auto calibration isn't working properly, or your printer isn't equipped.

To do a Manual Nozzle Height adjustment, you'll need either a sticky note, or the calibration card included with some printers (Shown Below).

The first thing to do is to clean the nozzle so the calibration won't be contaminated. (This can sometimes affect auto calibration too. Before all calibrations, the nozzle must be clean. You can do this by heating it and wiping off any stray plastic with a paper towel.)

IMPORTANT: Before continuing, you need to wait for the nozzle to cool down to below 60c.

Next, while the printer is plugged into a computer or laptop, you need to open the Calibration Tab, found here:

The number in the blue circle is the current nozzle height. This will be different on your 3D printer, and this is what we will be changing as it is wrong. 

To bring the nozzle of the printer into the centre of the platform, you need to click on '5' as shown below:

Next, we need to pay attention to the number with the 'plus' and 'minus' buttons next to it, as shown below:

You'll need to place your calibration card or sticky note on the print bed of the printer, directly underneath the nozzle. Then using the 'plus' button, incrementally raise the bed until it seems to not move anymore. At this point the bed is still moving, just not enough for the naked eye to see. Keep pressing the 'plus' button, while simultaneously moving the calibration card or sticky note back and forth underneath the nozzle. The bed will eventually rise up enough that you will feel a small amount of friction between the nozzle, and the card or sticky note. If you feel too much friction, you can use the 'minus' button to bring the bed down ever so slightly.

The aim here is to have the smallest amount of noticeable friction while moving the card or sticky note back and forth under the nozzle. If this is the case, you've found the perfect height for the printer! To save this new height, click on 'Set' as shown below:

Click 'Confirm' and the printer will now remember that number instead of the auto calibration number.
