=How to print with dual extruder=
 +
Before reading this text,please make sure you have already read the set up guide of the version of 13B single extruder and you can use it to print 3D models. If not, please learn how to operate the single extruder. Of course, you can take this one as the single extruder version to start.
 +
 +
'''Step 1'''
 +
 +
Open Repetier Host,click Config/Printer Settings to set up the connection.
 +
 +
1. Name your printer.
 +
 +
2. Select the corresponding COM port and baud rate. Baud rate is generally 115200 or250000.
 +
 +
3. If you are not sure about the COM port, you can check it in your device menager.
 +
 +
[[File:Printing setting1.jpg|500px]]
 +
 +
'''Step 2'''
 +
 +
Set up your extruder
 +
 +
1.Choose the number of extruder, here we choose 2.
 +
 +
2.Set up the diameter and color of filament
 +
 +
3.Offset X/Y refers to the distance between the two extruders,which can be adjusted based on real situations. You can leave it alone now.
 +
 +
[[File:Printing setting2.png|500px]]
 +
 +
'''Step 3'''
 +
 +
Set up the shape of printer
 +
 +
Choose Classic printer as the printer type.
 +
 +
Home X: min  Home Y: min  Home Z: min
 +
 +
Print height: 150
 +
 +
[[File:Printer setting3.png|500px]]
 +
 +
Now,you can click the Connect button on the left corner to check whether it can connect with your printer. If it fails, please recheck the COM port and Baud rate.
 +
 +
'''Step 4'''
 +
 +
Manual control
 +
 +
[[File:Printer setting4.png|500px]]
 +
 +
1. X home
 +
 +
Click X home to home the X axis, or you can click the right/left arrow to move the axis to check whether the direction and distance is normal or not;
 +
 +
2. Check Y axis and Z axis respectively in the same way
 +
 +
3. Click the icon of heated bed on RH to heat up the bed. observe whether the temperature is rising to a pre-set value
 +
 +
4. Click the icon of heated bed and extruder, observe whether it is heating up to the pre-set temperature and keeps at that value
 +
 +
5. When the temperature of extruder surpass 170 °C , choose extruder1 and extruder2 respectively, you can move them and check their directions
 +
 +
'''Step 5'''
 +
 +
leveling the two extruders.
 +
 +
Leveling the two extruder is very important if you want to printer with two extruders at the same time.
 +
 +
First, you can adjust one extruder to make it parallel with the surface of the heated bed in (the same way you level for the single extruder) , click the button of Z home to adjust the distance between the nozzle and the heated bed, make sure the vertical distances of the nozzle to the four corners of the bed are the same.
 +
 +
Then, you can adjust the distance between the second extruder and heated bed by adjust the screws, as shown in the following picture:
 +
Loose the screws, you can adjust the distance between two extruders and heated bed.
 +
 +
[[File:Printer setting5.png|500px]]
 +
 +
[[File:Printer setting6.png|500px]]
 +
 +
you may need to adjust again and again at this step to get both extruders in Parallel to heat-bed and with equal distance.
 +
 +
But it doesn’t matter, once you level them, you wont bother to adjust it later.
 +
 +
The settings mentioned above are set on Repetier Host,which only involves  the control of 3D printer and the preview of model.
 +
 +
All the settings don’t concern the final printing effect but the slicing. So we will continue with the slicing setting. The slicer is independent with Repetier Host. So,should we set up slicer? Take it easy,let’s see whether our printer can run normally.
 +
 +
'''Step 6'''
 +
 +
If the printer goes well. We can go on with the slicing. First let’s get a quick view of the slicer.
 +
 +
RepetierHost supports many slicers, Slic3r and CuraEngine are most frequently; Slic3r is more powerful in function, but CuraEngine’s comes with more optimized slice velocity.
 +
 +
[[File:Printer setting7.png|500px]]
 +
 +
You can choose slicer here. Upon selecting the slicer, please click Configuration, RepetierHost will bring up a wizard of the corresponding slicer that will walk you through the configuration.
 +
 +
Here we take Slic3r as an demonstration. As to the configuration of CuraEngine,we will pick it up in the follow-up study in our forum www.geeetech.com/forum/, so, please stay tuned. If you are experienced in CuraEngine, we would be very appreciated if you can share with us.
 +
 +
Next, download the file:[http://www.geeetech.com/wiki/images/0/06/I3B_2E.zip  two_color_cube.zip], unzip the file and put it somewhere, you will need it later.
 +
 +
 +
'''Step 7'''
 +
 +
Click Configuration,open Slic3r
 +
 +
[[File:Printer setting8.png|500px]]
 +
 +
'''Step 8'''
 +
 +
We have prepared a set of parameters for I3B_2E dual extruder, that is, I3B_2E_config_bundle.ini. You need import those parameters to software slic3r from here.
 +
 +
In Slic3r,  under file> Load Config Bundle..  navigate to the folder we just downloaded and unziped, open I3B_2E_config_bundle.ini,

[[File:Printing setting11.png|500px]]
 +
 +
'''Step 9'''
 +
 +
After loading, you can find the option of Geeetech_I3B_2E in the drop-down manual.
 +
 +
[[File:Printing setting12.png|300px]][[File:Printing setting13.png|300px]][[File:Printing setting14.png|300px]]
 +
 +
In my case, i use the geeetech pro C model,(i refer the I3B_2E in this article),extruder is MK8(1.75cm-0.4mm),PLA filament, so we choose Geee_I3B_2E, PLA 1.75mm, and Geeetech_I3B_2E respectively .
 +
 +
All the parameters you set can be saved, you can select it in RepetierHost next time.
 +

Install the drivers and software

Install the drivers

Installing Drivers Before printing, you’ll need to install drivers. The kind of driver that a Prusa I3 requires in order to operate properly is called a USB Serial Driver. A USB Serial Driver is software that establishes a COM port.

Plug the USB into a USB port on your computer. Windows Update should automatically find and install the drivers. You’re done with installing the drivers!

Windows 8

When you attempt to install the unsigned 3rd party driver on Windows 8, you will most likely not be able to install because the file is not digitally signed. To get around this restriction, you must temporarily remove this restriction by following the instructions here .

Once you have followed the directions to disable driver signature enforcement, download the driver and click to install. This is only a temporary change, however, and restarting your computer after you have installed the driver will return your computer to its normal state.

Note that this involves restarting your computer, so make sure to close out all other windows. You may want to print out these instructions so you can refer to them while your computer is restarting.

Windows Manual Install

Note: In some cases the drivers will not install on their own. The drivers for Windows can be found in the following link:

drivers for GT2560 and Sanguinololu

Drivers for rapms 1.4


If the driver was not automatically installed, you may see this screen:

INSTALL 1.png

In this case, a. Click “Change Settings…” b. Select “Install driver software from Windows Update”. c. Click “Save Changes”. The FTDI drivers should now install successfully.

INSTALL 2.png


Attention: For those having difficulty selecting your COM port

If you have installed the USB serial driver successfully and you are still not able to connenct to your printer in Repetier Host, then windows has not recognized the newly installed driver. In Repetier Host, you may even notice an error message that is similar to this one:

Serial com error:System.IO.Ports.SerialErrorReceivedEventArgs

In some situations, a computer running windows will not automatically recognize a newly installed Serial driver. This means that you will have to update your newly installed driver manually.

To manually update the driver, you will first need to plug the USB cable into your printer and attache the other end directly to one of your computer’s USB ports. Now, enter the ‘Device Manager’ in Windows and navigate to the hardware category called Ports (COM & LPT) and then left click on it once. You should notice the Ports category expand to reveal a Sub-Category called USB Serial (Communication Class, Abstract Control Model) (COM X); where X is the COM port number. You should be looking for that COM port number in Repetier Host after this procedure is completed; which can be found in “Printer Settings.”

INSTALL3.jpg

You will need to right click on the USB Serial Sub-class and select proprties. In the drivers tab you will find a selection to update drivers, click on Update Drivers to access the next menu.

Now that you have selected which driver to update, you will have to tell Windows where the “updated” driver can be found. You should be presented with two options. Select “Browse my computer for driver software” to locate and install the driver software manually.

Install 4.jpg

Next, you will be greeted by a menu that allows you to “Browse for driver software on your computer” You will be presented with two choices, select “Let me pick from a list of device drivers on my computer.” Now select the Serial port device and proceed with the installation.

Install 5.jpg

That is pretty much all there is to it. You will then see an installation indicator bar.

Install 6.jpg

Once the installation is complete you will be notified that “Windows has successfully updated your driver software.” You will be prompted to restart your computer; you should do so.

How to print with dual extruder

Before reading this text,please make sure you have already read the set up guide of the version of 13B single extruder and you can use it to print 3D models. If not, please learn how to operate the single extruder. Of course, you can take this one as the single extruder version to start.

Step 1

Open Repetier Host,click Config/Printer Settings to set up the connection.

1. Name your printer.

2. Select the corresponding COM port and baud rate. Baud rate is generally 115200 or250000.

3. If you are not sure about the COM port, you can check it in your device menager.

1. X home

Click X home to home the X axis, or you can click the right/left arrow to move the axis to check whether the direction and distance is normal or not;

2. Check Y axis and Z axis respectively in the same way

3. Click the icon of heated bed on RH to heat up the bed. observe whether the temperature is rising to a pre-set value

4. Click the icon of heated bed and extruder, observe whether it is heating up to the pre-set temperature and keeps at that value

5. When the temperature of extruder surpass 170 °C , choose extruder1 and extruder2 respectively, you can move them and check their directions

Step 5

leveling the two extruders.

Leveling the two extruder is very important if you want to printer with two extruders at the same time.

First, you can adjust one extruder to make it parallel with the surface of the heated bed in (the same way you level for the single extruder) , click the button of Z home to adjust the distance between the nozzle and the heated bed, make sure the vertical distances of the nozzle to the four corners of the bed are the same.

Then, you can adjust the distance between the second extruder and heated bed by adjust the screws, as shown in the following picture: Loose the screws, you can adjust the distance between two extruders and heated bed.

Printer setting5.png

Printer setting6.png

you may need to adjust again and again at this step to get both extruders in Parallel to heat-bed and with equal distance.

But it doesn’t matter, once you level them, you wont bother to adjust it later.

The settings mentioned above are set on Repetier Host,which only involves the control of 3D printer and the preview of model.

All the settings don’t concern the final printing effect but the slicing. So we will continue with the slicing setting. The slicer is independent with Repetier Host. So,should we set up slicer? Take it easy,let’s see whether our printer can run normally.

Step 6

If the printer goes well. We can go on with the slicing. First let’s get a quick view of the slicer.

RepetierHost supports many slicers, Slic3r and CuraEngine are most frequently; Slic3r is more powerful in function, but CuraEngine’s comes with more optimized slice velocity.
