could be 110 centigrade.
Do not put your hand into machine when printing, in case of
crushing.
The power supply use 110V-220V~50HZ alternating current,
the tripod socket must be grounded, don’t add another power, in case
of fire or electric shock.

Printer Operating
1. LCD display interface
2. Filament feeding
Assemble the filament holder with M6 screw and allen wrench.
Pic 44
Pic 45

Press the button to feed the filament.
Pic 51
Pic 50
Pic 52
Clockwise rotate the button of
14 circles.
The material will flow out freely.
---3D printer user manual

Pay attention to these notice:
(1)Please change the filament when length of filament remained is
less than 15cm, do change in time. Pay attention to the end of
filament entering into the feeding mouth totally.
(2) When filament change, the extruder temp. should be over 170
centigrade, feeding is clockwise, retraction is anticlockwise.

3. Platform adjustment
(1) Adjust the platform at a suitable position, and then spread glue on
it.
Pic 53
(2) Smooth the glue by a shovel blade, the glue will solidify on the hot
bed when preheating.
Pic 54
Spread some glue on the glass evenly before hot bed adjustment. Show
as Pic 62.

Do the following steps: Prepare a A4 paper and put it between the hot
end and hot bed all around the corners, make sure the paper cannot
out of their, that means it is the right distance.

Select “Print from SD” from LCD display---Select the gcode you are
going to print (such as : 123.gcode). The printer will be automatically
heating up to the temp. which has setted in the software , then press
the rotary button, the printer will automaticlly work up.
*The distance between nozzle and platform is one of the most
important factor that effect the printing result.
Far distance: Fine round , uneven, gap and tilt . In this case, printing

is not good and easy to move.shown as picture:
Close distance: the path is too flat and the side of path will upwrap,
what’s more, it will damage the nozzle, show as pic 75.
Right distance：Flat skinning, gapless, shown as picture 76:
