During printing, if the temperature does not match with the speed, it can be adjusted by

the rotate button.

Speed: Print speed. The percentage of compilation speed, for example 121%, means the

compiling speed multiplied by 121%. For example, the print speed of compilation is 50,

if speed is 121%, then the actual print speed would be: 50 X 121%=60.5.

Nozzle: Nozzle temperature. Choose: Tune Nozzle. Rotate button can set the nozzle

temperature.

Hot-bed: Hot bed temperature. Choose: TuneBed. Rotate button can set the bed

temperature.

Chapter 4 Adjusting print platform

The platform might needs to be adjusted during printing





28

4.1 Coarse adjustment

First, set the four springs at the bottom to the shortest, then press the LCD rotate button,

choose ‘prepare-Auto home’.

Hold the platform, and then shut down the power, eyes look straight forward to the

platform, push the extruder manually, adjust the distance between the extruder and

platform from the front, back, left and right, the distance should be approximately about

1 piece of paper.

If the distance is far away, please loosen the regulation nut at the hot bed bottom. If it

is too close, please tighten it.

4.2 Fine adjustment

Choose a model and start to print, when it starts, please look straight forward to the

platform and make sure the distance between the nozzle and platform is about one piece

of paper.

If the filament is zigzag shape, it means the distance is far away, it drops off from the

nozzle, please loosen the regulation nut. If the filament is too thin, it means the nozzle

has stocked the platform, please tighten the regulation nut.

If you find the distance is far away or too close during printing, please stop printing.





29

Adjust the platform regulation nuts, test a few more times until the distance is perfect.

When print for the first round, it is better to pay close attention to it so as to make sure

the nozzle will not hit the platform.

Chapter 5 Installing software

Install up-level computer program CURA, the catalogue is in SD card：

Cura_14.03_English.

The software is updating, other version Cura maybe in your cards, but it’s available

too.

Open the software installation package, do as the software prompt, when

installing the component, please make sure you have checked the OBJ and AMF file if

you need to open them when operate CURA.as shown below.

After it is successfully installed, you will see the screen as below.

Chapter6 Solution when unable to install Arduino driver

If you are using starter edition windows system, a system error might prompt up as '

the system can not locate the specified file' when installing Arduino driver, as

shown below.

That is because the starter edition window system has deleted some not commonly used

driver info.





31

To solve this problem:

1.First, open C:\windows\inf\setupapi.dev.log

This file contains relevant plug-and-play device and driver program installation info,

and of course it tells you the reasons why it fails to install the Arduino driver.

Open this file, slide to the end of the file name, you can see the info as shown below:

This missing file is the reason why the Arduino cannot be installed.

2. create a new file folder: mdmcpq.inf_x86_neutral_******** under path

C:\Windows\System32\DriverStore\FileRepository\

' ********' this depends on different computers, please refer to aboved

setupapi.dev.log for prompt.

For example, my computer prompt:

C:\Windows\System32\DriverStore\FileRepository\mdmcpq.inf_x86_neutral_9f203c

20b6f0dabd

Indicating that I have created a same name file folder under path

C:\Windows\System32\DriverStore\FileRepository\ :

3. Download below file and decompress it, put it in the new folder

mdmcpq.inf_x86_neutral_********





32

4. Re-install the driver, and now it will be successfully installed.

Chapter 7 Software introduction

7.1 Quick print

Press Expert and choose switch to quick print, as shown below.





33

7.2 Full settings

Point the mouse to the parameter, you can see the details of every parameter.

7.3 Parameter introduction

7.3.1 General setting

1. Layer height: the thickness of every layer of the filament, support 0.05-0.3, value

between 0.1-0.2 is recommended.

Effect: The thinner of the layer is, the finer the surface will be, the time of print will be

longer too.

2. Shell thickness: the thickness of the outside wall of the model, 0.4 per layer of

filament，value between 0.8-2.0 is recommended.

Effect: The thicker the wall is, the more intense it will be. The time of print will be

longer too.





34

3. Enable retraction: retract the filament when print.

Effect: Without retraction, it will over pull the filament which will impact the overall

printing.

4. Bottom/top thickness: the thickness of the bottom and the top.

Effect: If the printed model has damaged holes on the top, please adjust the thickness

figure accordingly.

5. Fill rate: 0 for hollow, 100 for solid.

Effect: It can save print time by decreasing the filling, but will impact the print strength.

Hollow might lead to failure of completing the print model because the wall is too thin.

Therefore appropriate filling is necessary.

6. Print speed: recommend 40-60mm/s.

Effect: Slow down the speed appropriately, allow reasonable cooling time while

printing, the model will be printed out better.

7. Printing temperature: the nozzle temperature while printing, ABS recommend 210-

230, PLA recommend 190-220.

Effect: Too low temperature makes extrusion stopping, and it will block the nozzle to

export filament.

8. Bed temperature: ABS recommend 90-110℃, PLA recommend 70-80℃.

Effect: If the temperature is too low and the filament is not adhesive enough, edge warp

might happen.

9. Support type: because there will be overhang during printing, the filament might drop





35

for gravity reason. Therefore, a support is needed. But not for all.

None: no support is needed.

Touching build plate: support from outside, only add support for the overhang part

outside of the model.

Everywhere: add to every part of the model as long as it is overhang, including inside

of the model.

Effect: If the model is overhang, it needs support. If not, the filament will drop during

printing.

10. Platform adhesion type: add a base and it can enhance the sickness of the print

model. None: no platform is needed. Brim: extra thick base, and attached cohesive

material around. Raft: net shape base.

Effect: Adding a base can enhance the thickness of the platform, Raft type base save

more material.

11. Diameter: diameter of the filament.

12. Flow: the flow speed of filament while printing.

Effect: Diameter is used in conjunction with the rate of flow. The bigger the diameter

is, the slower the filament come out. The bigger rate of flow is, the faster the filament

come out.

7.3.2 Advanced setting

1. Nozzle Size: 0.4.currently this figure is fixed.

2. Retraction speed: Speed at which the filament is retracted.

Effect: Theoretically the faster the better, but it might possibly lead to unable to feed

filament.





36

3. Retraction distance: the length of filament. These two parameter will only valid when

choose retraction allow in the general setting.

Effect: If the length of the retraction filament is too short, it will possibly lead to over-

pulled, if it is too long, the filament might be able to be loaded.

4. Initial layer thickness: thickness of the first layer.

Effect: The thicker the first layer is, the more adhesive the model will be.

5. Cut off object bottom: some models have an uneven bottom or lack off contact

surface, the bottom can be cut off partially.

Effect: For those models that doesn’t matter much with the bottom or need to be printed

separately, it can be cut off to print, the print outcome will turn out better.

6. Dual extrusion switch amount: double print matters. When setting the double print,

repeat the extrusion variable.

Effect: By setting a certain amount of repeat extrusion variable, two colors will be

adhesive to each other better.

7. Travel speed: the speed of the machine moving.

Effect: The faster it moves, the shorter it costs for printing.

8. Bottom layer speed: the print speed of bottom layer, slow speed can make the print

more adhesive.

Effect: Slow down the print speed of bottom layer appropriately enable the bottom

adhesive better, in this way, the print effect will come out better.

9. Infill speed: the speed of print filling.

Effect: Speed up the filling enable print faster.





37

10. Outer shell speed: the speed of print wall, slow print can make the wall print better.

Effect: Slow down the print speed of wall, the surface will be smoother.

11. Inner shell speed: the speed of the print in wall. Higher speed can shorten the print

time.

Effect: Speed up the in wall print can shorten the print speed.

12. Minimal layer time: the minimum print time of each layer, if print too fast, the

machine will slow down according to the minimum print time of that layer to ensure

enough cooling time.

Effect: Control the minimum print time of each layer to ensure enough cooling time.

13. Enable cooling fan: open the nozzle cooling fan to speed up the cooling.

Effect: It is used to speed up the cooling while printing, the print effect will come out

better. Careful use for ABS, it is easy to rip off.

45

Chapter 9 Print technique

FDM format 3D printer has its own print features, mastering those features can print

out perfect graphic. Summarized as follows:

9.1 Flat bottom

When start to print, choose the flat bottom side, because it starts to print from the bottom

and then all the layers up, so the bottom decide the whole print quality. Therefore, it is

essential to print the bottom layer, choosing a good flat bottom as the bottom layer is a

good start.





46

9.2 Avoiding overhang

Because the filament that come out from the nozzle is fluid during printing, it will drop

down for gravity reason, if there is any overhang in the printed image, the filament will

drop down. Therefore, we need to use software to form a support when print, and

remove it after print is done. It is same as building a house, because the concrete is fluid

which will drop down, so we need stake it off, and remove the wooden stakes after the

concrete is consolidated.

Same as construction, after removing the wooden stakes, it will leave the stake marks.

So after print finish, the support mark will be there. So if you want to improve the print

quality, you need to avoid overhang as much as possible.to improve, the following two

aspects must be done:

Choose the print direction, the one with minimum overhang





47

Overhang should be avoided starting from designing the graphic, 90°overhang can be

replaced by upward sloping, or separate the overhang part of the graphic and then stick

them all together with glue at a later stage





48





49

9.3 Assembling matching graphic tolerance

If the printed object is a graphic needed to be assembled, for example, graphic like

screw matching screw cap/toothed gear, because plastic will expand with heat and

contract with cold and also the inflated edge of the bottom during printing, the tolerance

should be bigger, normally set as 0.4m, it can be set according to the actual graphic.

9.4 Big size graphic print

If the printer volume is relatively big, PLA filament are needed, the feature of ABS

filament decide that it is not suitable for big volume graphic, it will easily split and out

of shape. So PLA is recommended for printing big volume graphic.

If the big volume graphic is still easy to get edge warping during printing, you can use

502 glue to stick the bottom, but do not put 502 to the nozzle.

Chapter 10 FAQ

1、Q: Got electrical shock when using the machine

The machine has a metal cabinet which comes with static electricity, it will not cause

harm to human body. The reason why it has static electricity is that the ground filament

has not been connected yet. To solve this problem:

1. Make sure the ground filament is set when laying the electric filament in the house.

2. Use another filament to connect to the machine metal cabinet (can be the bottom

under Z Axis), then connect the other end to a substantial metal object in the house, for

example the window.

2、Q：Paper is loosened and easy to be turned during printing

A：Possible causes

1. The distance between the printing platform and nozzle is too far away, it can be

adjusted by the four horizontal adjusting nuts. Make sure the distance is appropriate,

same as the thickness of a name card.

2. The temperature of the print platform is not high enough, the standard setting of the

temperature is about 75 if using PLA and 100 for ABS.

3. The print platform does not have the high temperature resistant adhesive, to

improve the engagement, high temperature resistant adhesive is recommended.

4. Cooling fan on the platform is turn on too early, unplug the interface, but do not





51

unplug the cooling fan of machine.

3、Q：Unable to load the filament

A：the reasons could be as follows

1. The temperature has not reached the best melting point of the filament. Adjust the

temperature, usually to increase.

2. The filament tie knots on the feeding tray, so the filament is stuck, cut it and then

adjust the filament, the print could be resumed.

3. The distance between the print platform and nozzle is too close, it will stuck the

nozzle. Low down the platform by adjusting the horizontal adjustment nuts.

4. The filament diameter is too large, cut it and change to a better one.

5. Nozzle is damaged, contact the customer serve if it is damaged for all kinds of

reasons.

4、Q：Displace during printing

A：possible causes

1. It could be winded or blocked, check whether the sliding cross-shaped base is

winded by filaments or blocked by a certain objects, eliminate them.

2. Too much dust on the Axis leads to the increase of friction. Use a tissue or alcohol

pad to clean the dust.

Chapter 11 Notice
