Hi,
As I promise and with the great help of Tweakie I finalise the extruder controller board and write down a small tutorial for the people who may want to convert their desktop CNC to a 3d printer.

Hi Tweakie,

This will be a completely open source project. I will purplish all the drawings, the design files and the software code. So the people who wants to build their own can use the design files. If you have not too much time and ability to produce such circuit boards and hardware, you can buy from me as a kit and start to print with your desktop printer immediately.

PS: English is not my mother language. If there is someone agree to read the documentation (5-10 pages) and wants to correct the typo and grammatic errors will get all the information before publishing as open source.

Regards,
Nuri Erginer

Hi,

I am getting e-mails from people who want to buy the control board and a hole CNC to 3D Printer conversion kit. I am almost finished a tutorial about the conversion and will send the link to this post.

Can you please reply to this post if you want to have a board or the hole kit. So that I will have the list of people for the first production.

Regards,
Nuri Erginer

Hi everybody I am back again.
Sorry I can not write for a while. But the news are good. I have finished the control board Here its features:

atmega8 and arduino code (standalone no PC connection)
LCD (to read temperature values)
two trim-pots (to set two separate temperature value one for nozzle one for build platform)
one thermocouple input
two thermistor input
two relay output
two power transistor output

With this board you can easly convert your desktop cnc to a 3D printer.
Here is a picture of the board.



I will prepare a web side to tell people how to convert their cnc to a 3D printer. All the software (including modified skeinforge) and the hardware as a kit will be there.
Please e-mail me if you interested in buying this board nerginer@gnexlab.com

The first group will purches the board with a compatitive price. I will mass produce according to the number of people willing to buy the board.

Regards,
Nuri Erginer

Can you tell me how you modified Skeinforge from the 'E' axis to the 'A' axis? I am already well into building a stand-alone 3d printer and this is the problem between Mach and Skeinforge I've run into. My feed steppers are on the 'A' axis and I need to change them.

There is no option for doing this in skeinforge so I modify the source code

I am at the end of the design phase of the ver2 circuit board. It will do all the stuff. With this circuit board I will release the modified skeinforge software and mach3 configuration xml files. I will let you know very soon.

Please find below the images of my test environment which use mach3.

Thanks Tweakie!

Let me tell you what I did up to know. After then I will share all the information.

As you know there are two approaches to the extrusion motors in 3d printing community. One is 5D concept that use a stepper motor as a filament feeder. The other is a gear head dc motor.  For the first one I slightly modify the skeinforge software for 'E' letter. For the forth dimension skeinforge use the letter 'E' as an axis definition (like X,Y and Z) After the small modification software produce gcode with letter 'A' instead of 'E'. This is suitable for mach3 to read the code and control the stepper extrusion motor in desired speed. The arduino based circuit is only dealing with extruder temperature, build platform heating and cooling fun control. This works fine. Feed rate, extrusion speed and temperature are the main parameters that you have to fine tune for better print quality.

The second concept is a gear head dc motor. I use the spindle relay for on-off control of the dc motor. I just write two M-code macro to define the M101 (start extrusion motor) and M103 (stop extrusion motor). This time arduino circuit deal with PWM motor speed control with a potentiometer.  

I will soon share the information so that you can build a kit by yourself (or buy one) and screw it to your mach3 cnc and start using it as a 3D printer.

what I am trying to do is easy switching from a cnc to 3d printer. Mach3 will be the software. You will plug a extrusion head instead of a spindle and you will begin to print. A arduino based circuit board will control all the stuff like extrusion temperature, extrusion speed and build platform heating. I prefer to separate the 3d printer requirements from mach3 software. This will not disturb the mach3 to run the cnc code and will help people to switch between cnc and 3d printer.

I am using skeinforge (http://fabmetheus.crsndoo.com/)
it gets 3d stl file as input and produce g-code. it has lots of parameters for fine tuning.
