Make sure to keep an eye on your print until it finishes. Every file you print has its own characteristics
and sometimes it will surprise you what happens. Also the beginning of the print is critical to the final
results and you should make sure it adheres correctly.
Note : As print starts, keep an eye on the filament spool to ensure it
does not bind or wrap around the brackets. This is especially true for
new spools of filament.

Your printer shipped with auto bed leveling. To activate the bed probing you must add the G29
command to the start gcode section in your slicing program. Refer to the Auto Bed Leveling Guide for
more information. If you would like to level your extruder left to right you can manually turn the lead
screw on one side until the x-axis is level.

If you find your extruder hotend is either too far from
the bed or too close, you can adjust the auto bed
level sensor height by turning the two screws just
below the LED light bar. These screws are tensioned
by a spring and you can raise or lower the sensor as
needed.
Tips for dialing in the z-axis height:
1. "Prepare > Auto Home" the printer.
2. When it is done the extruder should be 1.9mm above the bed. Then go to "Prepare > Move
Axis > Move 0.1mm > Move Z". Lower or raise the extruder until you can barely slide a
business card between the hotend and the print surface.
3. Then look at the LCD screen and take note of the height of the z-axis. If the number is negative
then you will need to manually Raise the touch sensor bracket by that amount. Alternatively if
it is positive you will need to Lower the touch sensor bracket by that amount.
4. Repeat until the extruder is the correct height.
