Notice Before First Use
1. Power Supp ly Voltage Selection:
lPlease a djust the voltage to match your local
voltage be fore first use, switc h to 115V (for
operation 100-120 V) , or to 2 30V (for ope ration 22 0-
240V).（The default fa ctory voltage setting is 230V）
Please r efer to the included USB Drive for a Setup and Insta llation Ins tructional Video.
Voltage Requirements for some countries:
①CA/US/JP:100-120V
②DE/FR/UK/AU/RU/IT/ES: 220-240V
lThe Y-ax is slider plate is adjuste d at the factory, but the machin e's pulle ys may be loose due to trans portation. If
the printi ng platform is shak y or loose, you can us e an open -end wre nch to slowl y unscrew the hexagon al isolati on
column unde r the pla tform unti l the Y-a xis slide r plate slides s moothly with out shakin g!
lSimilarly, you can adj ust the he xagonal is olation colum n undern eath the p rint head if it bec omes wobb le or loos e.
There ar e also cor respondin g isolation columns for the pulle ys on both sides of t he gantry that can b e adjuste d.
2. Y-Axis Slid er P late Wobble:

When first running the machine, the distance between the platform and the nozzle needs to be
calibrated in the leveling mode, which is about the thickness of a piece of A4 paper .
Note that the leveling sensor only
detects the metal platform plate, for
example, replacing the glass platform
for leveling will not produce detection
effect, which will cause the nozzle to
squeeze the platform.

lWhen the printer is powered on, select 【Level】.
lEach axis of the printer automatically returns to the home position, after entering the leveling page, place a sheet of A4 paper between the nozzle and the
platform, and adjust the height compensation values using the screen controls to increase or decrease the distance between the nozzle and the platform
(P2), and slide the sheet of paper back and forth several times, until there is a slight amount of noticeable friction generated. At this point, the center point
calibration will be completed. Next, select the auxiliary leveling option [ ] , to calibrate the 4 corner points of the platform with the same sheet of paper
by adjusting the hand-twisting nuts found under the heated bed, and once again sliding the paper until friction has been detected and the paper can be
pulled out, but not slid under the nozzle. This will complete the auxiliary leveling calibration.
lAfter completing the manual auxiliary leveling process above, next select the automatic leveling option from the menu and your printer will begin the
automatic calibration process. [ ]
lYour printer will enter a heating state during the automatic calibration process as the nozzle is heated to 140ºC and the heated bed to 60ºC (Please adjust
the heated bed temperature to the recommended temperature of the filament you intend to use to ensure accurate leveling values) .
lAfter reaching the preset temperature, begin the 36-point automatic bed calibration.
lWhen completed, perform Z-axis compensation setting: Place an A4 paper between the print head and the platform. Adjust the compensation value by
clicking, and gently slide the A4 paper. When the A4 paper can be pulled out but cannot be pushed in, the leveling is complete.
