4.3 Heating

Here you can set the heating temperature of heat bed and extruder. Temperature of extruder can not

be set too high or too low, otherwise the extruder can easily have blockage. You need adjust the

temperature according to your filament.

Generally speaking,

PLA：extruder 190°-210°/heat bed：55°

ABS：extruder 240°-250°/ heat bed：75°-80°， In order to make the filament stick on the heat

bed easily, please add ABS glue on the printing platform.

Notice: we set the number of extruder as 2, but actually there is only one nozzle. When you are

heating extruder 1, extruder 2 is also heated by default. Therefore, you don’t need

GEEETECH

www.geeetech.com Tel: [phone] Fax: [phone] - 858

ShenZhen GETECH CO.,LTD

- 11 -

simultaneously heat extruder 1 and 2.

If you can’t heat extruder or heat bed, please refer to FAQ.

At this moment, heat bed, extruder 1 and extruder 2 are separately heated up to 55℃ and 195℃.

4.4 Extruder

After the extruder reaches the preset temperature, we need to make sure filament0 and filament1 are

both working.

Notice:

At any time, please make sure that filament 0 and filament 1 are simultaneously inserted into the

nozzle. Don’t only insert filament 0 or filament 1. Otherwise, once no matter which kind of filament

GEEETECH

www.geeetech.com Tel: [phone] Fax: [phone] - 858

ShenZhen GETECH CO.,LTD

- 12 -

is fused too much, it will overflow upwards and then block the hole through which the other kind of

filament enters the heating block from the barrel.

No matter in the process of cleaning filament or inserting and removing the filament, don’t insert or

remove the feeding pipe near the hot end. Once the filament in it is fused too much and feeding

pipe is not inserted entirely, the fused filament will overflow up and then cause blockage. If this

kind of problem happens, it will be difficult to clean the filament.

5. Move axis

X,Y,Z axis can move at a resolution of 10mm, 1mm and 0.1mm.

Extruder 1 and extruder 2 can only move at a resolution of 1mm and 0.1mm.

5 Heat bed leveling

You need do leveling for nozzle and four corners of the heat bed. Next is one of the leveling

methods.

Rough adjustment

There is a Z axis endstop trigger (M3*50 screw) on the left end of X axis. Tightness of the spring

determines the reset position of the Z axis. Through adjusting M3*50 screw, try to make the reset

position of Z axis the same with the position where the extruder head exactly stops on the heat bed.

Fine adjustment of the relative location between extruder head and heat bed

1. Set Z axis to initial position

2.

After unlocking the motor, manually move X axis and Y axis, and move the extruder to four

corners of the heat bed in turn. Because of former rough adjustment, the extruder head is very

close to the heat bed.

3. Put a piece of flat A4 paper in the inter space between extruder head and heat bed, then drag the

paper to test if there is a slight resistance. If there is, it means the extruder head is already at the

right position. If not, you need adjust the screw of this corner of the heat bed to slightly raise or

lower the heat bed.

printing effect of different colors and blending colors.

There is a menu in Mixer shown as following list:

Prepare used for returning to upper Prepare Menu

Filament 0: displaying current proportion of Filament 0. Press to enter, the value can be adjusted.

Filament 1: displaying current proportion of Filament 1. Press to enter, the value can be adjusted.

Note: extruder 1 is corresponding to filament 0, extruder 2 is corresponding to filament 1

The sum of the proportion of Filament 0 and Filament 1 is 100% . If you manually adjust either of

the two values, system will automatically work out the other value. The proportion will not change

unless you readjusting it or choosing template again.

OFP: Over Fusion Protect. Through restricting the proportion of filaments, OFP can avoid

blockage caused by the long-time stay in the extruder and over fusion carbonization of the two

kinds of filaments. It can also avoid bad printing effects brought by filament’s over-softness after

over-fusion. This function is turned on by default. When it is turned on, the maximum proportion

of filament is no more than 96%, and the minimum proportion is not less than 4%.

GEEETECH

www.geeetech.com Tel: [phone] Fax: [phone] - 858

ShenZhen GETECH CO.,LTD

You can also modify the OFP proportion

OFP Max: maximum proportion of filament feeding

OFP Min: minimum proportion of filament feeding

Store Memory: save

If it is not saved, the printer will agree that current parameters are valid. After restarting the printer,

last setting is recovered.

Templates: Menu entrance of blending template. Used for the storage of blending templates.

The following is Templates menu. Templates are used for printing gradient color effect.

Template 1: Once this template is chosen, Filament 1 will change to Filament 0 within the height of

2mm;

Template 2: Once this template is chosen, Filament 0 will change to Filament 1 within the height of

2mm;

Template 3: Once this template is chosen, Filament 0 will change to Filament 1 within the height of

10mm;

into effect immediately and the proportion is determined by the last operation.

Print alternating color

You can use M201 to print alternating color like using other printers with dual extruders. Please

calculate the printing time in advance, and adjust the proportion of filament 0 and filament 1 when

it is time to change color.

Method 1：

Change filament 0：96%, filament1:4% to filament 0：4%，filament 1:96%，and this is changing

from filament 0 to filament 1.

Method 2:

Select template 1, switch from filament 0 to filament 1

Select template 2, switch from filament 1 to filament 0

7.2 Introduction of customizable gradient template

Custom template allows user to set the parameters of gradient color printing. It provides six

customizable templates for user to set and they are named as Custom1 to Custom6. User can set

GEEETECH

www.geeetech.com Tel: [phone] Fax: [phone] - 858

ShenZhen GETECH CO.,LTD

- 36 -

under the Mixer >Custom menu. Each template includes parameters of Start Gradient Percent, End

Gradient Percent, Start Height, and End Height. Perform a Store Memory to Save it when the

setting is done.

Next i will show you how to set and use a customized template.

7.2.1 Parameters Setting Instructions:

1. All the settings are set based on Filament0 by default.

2. According to the work principle of Mixer, the sum feeding rate of Filament0 and Filament1 is

100%. After Filament0 is set, the system will automatically calculate the corresponding feeding rate

of Filament1.

3. Start percent and end percent can be set at will. The sum of them is not always 100%. Users can

adjust it according to their requirements.

E.g., you can set the start percent of Filament0 as 30% and the end percent 60%.

Filament0

Filament1

Total

Start percent

30%

70%

100%

End percent

60%

40%

100%

Total

90%

110%

4. Start height and end height are print heights above the bed not the current printing height. Start

height and end height must be greater than current printing height, otherwise they will be regarded

as invalid. For example, current height is 40mm above the bed, but the start height in the template

setting is 20mm and the end height is 30mm. It has overlapped part with current print height, so the

system will automatically ignore this template and continue printing with the current template.

5. When one templates is finished, printing will continue with the feed rate percent that is fixed,

without gradient effect, until you choose a new template.

8. FAQ

1. Homing direction or motor direction is reversed.

If you have this problem, please modify the logic value of corresponding motor in the menu of

control>printer settings of LCD. Change the motor direction of corresponding axis from True to

False or change it from False to True.

2. Instruction for the heating of extruder 2

In Repetier-Host, we set the number of extruder on M201 as 2, which means there are 2 extruder

motors but only one hot end. You don’t need simultaneously heat extruder 1 and extruder 2.

Extruder 2 is heated by default when extruder 1 is heated.

GEEETECH

ShenZhen GETECH CO.,LTD

- 47 -

3. Extruder can’t be heated

For this problem, please check following electronic components

1） If the power supply works normally.

2）If there is a poor contact between the heating wire and the socket of control board. You should

make the copper wire in the heating wire have a good contact with the cooper sheet of the

socket.

3） There is an open circuit in somewhere of the hot end and heating wire (resistance is infinite),

which causes no current passing through.

4） MOSFET may be burned-out.

4. Extrusion is not fluent or blockage problem

1）Whether the temperature setting of printer is proper or not. There are different melting

temperatures of different filaments, and please choose proper heating temperature. Filament

is easy to get carbonized when the temperature is too high; while the extrusion of filament

will become less fluent when the temperature is too low.

2）The hot end cannot dissipate heat in time. Maybe this is because the fan wire of the hot end

has a poor contact with the socket, which causes the fan of hot end stopping working.

3）The inter space between the nozzle tip and heat bed is too small, and this causes difficult

extrusion. In order to get a proper space you can do like this: after z axis going back to

home position, put an A4 paper between the nozzle and the heat bed and you can slide the

paper under slight resistance.

4）The filament faces a large resistance in the path from the extruder to the nozzle. The

resistance may be produced by the motor, feeding pipe or nozzle.

5）The torsion of the extruder motor is insufficient. You can adjust the potentiometer on

A4988 to enhance the current.

If there is blockage, please refer to following steps to solve it.

1) Heat the extruder to the temperature of the melting point of the filament.

2) Press the lever of the extruder motor and pull out the filament. If the filament is broken in the

3) Check the filament which has been taken out. If it has a sign of being slightly broken, please cut

it off and reinsert the filament.

4) When you are inserting or pulling out the feeding pipe which is close to the hot end, it is easy to

block the nozzle completely if your operation is not proper. Please mind your operation.

Mark the current inserting depth of the feeding pipe in the barrel. Press the blue quick plug above

the barrel and pull out the feeding pipe. Clean out the filament which is stuck in the pipe, then

reinsert feeding pipe. Please notice that the depth of inserting the pipe should be the same with

before. If the depth of inserting is shallower than before, melted filament will overflow upwards

and takes up the place of feeding pipe, which makes the filament harder to enter the nozzle.

5) If you find too much filament gets accumulated in the hot end, please use needle to clean out

surplus filament. Then reinsert feeding pipe and filament. This process doesn’t need too much

strength; otherwise the PTFE in the barrel will easily be stuck to broken.
