1.1Safety Instructions
1) Please switch to the correct local voltage (115V-230V) before turning on the printer. Be sure
the switch is in the correct position or it will damage the power supply unit (PSU).
2) Be sure all wires are correctly connected before turning on the printer.
3) Don’t touch extruder head or hot bed when printing as they generate high temperature
which may cause burn.
4) Don’t leave the printer unattended when printing.
1.2Factory Test before Delivery
To ensure quality, each printer is tested at the factory. As a result, there may be filament residue
in the extruder head or on the hot bed, but it should not affect normal use. We provide the spare
nozzle in the accessory kit just in case.
1.3 Risk statement
1) Before color mixing or monochrome printing, make sure that there is the filament in the
feeding tube on both sides of the extruder head to prevent back flushing of the molten
filament inside the extruder head, resulting in clogging.
2) Make sure there is filament in feeding tubes on the both side of extruder head even using a
single-sided extruder for monochrome printing, moreover the filament in the other feeding
tube cannot be pulled out during the printing process.

6First print
6.1Leveling hot bed
The first layer is the key to a successfully printed model, which would directly affect the quality of
printing model and achieve a good bed adhesion. In order to avoid scratching nozzle and hot bed,
the factory default setting is a little high. Users need to level the hot bed and set the distance
between the nozzle and hot bed before printing. After the first-time bed leveling, users don’t
need to level the bed again. Details as follows:
1) Rough leveling
Please click the “Home” to enter “Leveling” interface on the touch screen. See picture (6-1). If
you click “manual level”, it shows “manual level” interface shown as picture (6-2).
（Picture 6-1）
（Picture 6-2）
Put a piece of leveling paper or A4 paper between hot bed and nozzle, Click the middle "5"
button, and select the appropriate precision (0.05mm/0.5mm) in the lower left corner to adjust
the height deviation value in the Z-axis direction until the distance between the platform and the
nozzle is about one sheet of paper. The thickness can be about 0.1~0.2mm, Slide the paper back
and forth to see if you feel a slight resistance. If yes, it means that extruder head is in the right
16
Shenzhen Getech Technology Co.,Ltd
place. See picture (6-3). After adjusting the height at position “5”, click “OK” to save current
value.
（Picture 6-3）
Please click the button in order from 1-4, At each corner, use the adjusting nuts under the bed to
set the distance between nozzle and hot bed to about the thickness of a piece of paper (Slide the
paper back and forth to see if you feel a slight resistance). Now rough leveling is finished. See
picture (6-4).
（Picture 6-4）
1) Accurate leveling
If you level hot bed with A4 paper, the first layer might be too high, too low or moderate.
a. Too high: If the distance between nozzle and hot bed is too far, filament will not stick to the
bed well. See picture (6-5).
（Picture 6-5）
17
Shenzhen Getech Technology Co.,Ltd
b. Too low: If the distance between nozzle and hot bed is too close, it prevents filament from
coming out, causes the extruder gear to click or grind on filament and even worse, it would
scratch nozzle and hot bed. See picture (6-6).
（Picture 6-6）
c. Moderate: Extrude filament properly and evenly. Stick to the hot bed. See picture (6-7).
（Picture 6-7）
In case of too high and too low, please adjust knobs under the hotbed slightly until you achieve
proper height. It may take some trial and error to achieve the best result. An example of good
first layer, see picture (6-8).
（Picture 6-8）
Note:
1) Be sure to adjust the height at center point (position5) on the touch screen, after clicking
“OK” to save its data, you can use then knobs to adjust the hot bed at the 4 corners.
2) When viewed from the above, turning the knobs clockwise, the hot bed will rise, and vice
versa.
3) Avoid the nozzle touching the bed; use a piece of A4 paper. Or it will scratch the bed.

10Function introduction
10.1Power -resuming capability
A30M has the power loss-resuming capability. When power recovery starts, it will pop up a
dialog to ask if continuing the unfinished print caused by power outage, choose “Yes “and it will
resume printing. See picture (10-1).
（Picture 10-1）
When it reaches the target temperature, the X and Y axes will auto home. The extruder will
extrude the residue in the nozzle. Use a tweezers to clean the nozzle before starting printing
again.
Note:
1) When power outage, move the nozzle away from the printing model in case the filament
oozes out on to the print.
2) Be sure to clean the residue in the nozzle before restarting the print or it would affect the
quality of the print.
10.2 Filament run-out sensor (optical)
Before using this function, first, you need to install the filament run-out senor module on the
machine and wire it. Please check filament whether it is turned on or not. Choose “Setting”>
“Filament”> “Detector”. See pictures (10-2, 10-3,10-4).

11 FAQ(Frequently Asked Questions)
11.1 Abnormal extrusion
1) The filament is tangled. The nozzle temp is too low to reach the melting temperature
required.
2) There is carbonized residue inside the nozzle.
3) Please replace it with the spare nozzle. Insufficient heat dissipation of radiator of the
extruder head causes the filament in the tube to melt in advance and the extrusion strength
is insufficient. Please check whether the cooling fan works normally.
4) The slicing speed is so fast that the nozzle speeding can’t match it. Please reduce the printing
speed.
5) Be sure the smooth in extruder inside after long-time printing. Please keep clean on a regular
basis avoiding plugging.
11.2 The gear of the extruder skips and makes an abnormal
noise
1) The nozzle is clogged; please refer to 11.1 abnormal extrusion.
2) Check whether the friction force between the extruder gear and the filament is enough.
Please clean the residue.
3) Check whether the voltage of the driver (Vref) of the extruder is normal, and try to
increase it by 0.1v until it works normally, max 1.2v.
11.3 First layer abnormal
1) Non-stick: a. the nozzle is too far from the hot bed. Please re-level the bed, try to stick
masking paper or glue stick on the surface of the hot bed.
2) Not extruding and the bed scratched: a. the nozzle is too close from the hot bed. Please
re-level the bed; b. check if the nozzle extrusion normal.
11.4 Layer shift
1) The printing speed is too fast. Please slow it down.
2) The belt of X or Y axis is too loose. Please tighten it.
3) The X or Y axis synchronization wheel is not fixed firmly. Please adjust the eccentric nuts.
4) The voltage of the driver of X/Y axis is too low.
