Mach3 Addon

  • Mach3 3D printer Add-on
I am very happy to announce that I have written an Add-on for mach3 which will allow you to use mach3 as a 3D printer Software. You will use mach3 software both for slicng the STL file and printing directly.
Please watch video in full screen…
Installation Notes:
– Please download the setup1.3.exe and install (may request administrator privilege. The user name and password is your own administrator user name and password)
– It includes Slic3r inside (
– It requires a Windows machine running .net Framework. You can download the .net Framework yourself here).
– You can change Slic3r settings by editing “gnexlab_config.ini” Which is inside Slic3r directory. You can also open it with Slic3r.exe in order to modify it. Do not forget to save it on the “gnexlab_config.ini” file.
Tested on winXP and Win7 systems.

    Hi Nuri
    Sorry to be a nuisance but I thought that version 1.3 was the latest but I have since found version 2.2 which I downloaded and installed. Maybe it is machine specific as it didn’t work satisfactory, giving me only 3 lines of g code.
    I found the slicer folder where you mentioned but on looking at the “INI” file the only entry that seems relavent to the “A” chanel of Mach3 was “Extrusion axis=”A” so I assumed that this should be OK. I still get the “A” axis designated with “E” when slicing a “SDL” file with version 1.3.
    Any further thaughts?


    • Hi James
      Please try to be sure which config.ini is being used with slic3r. I am not certain, but it must be gnexlab_config.ini
      You are very close to the solution. Investigate little more. You can run gnexlab_open_dialog.exe stand alone to understand what is going on.
      Hope this will help.

      Please do not hesitate to ask me any question.

        Hi again Nuri
        Still can,t get it working! In C:\Gnexlab\\Mach3\Addon\disp\Slic3r there are 3 “ini” files, all of which I have checked to make sure that “Extrusion axis=A”. When it made no difference I then changed all the “.ini” s to “.xxx” and this made no difference to the g code with the “E” prefix on the “A” chanel. I have therefore come to the conclusion that the program is not accessing the ini files at all. I then removed all traces of both Mach3 and the Gnexlag directories. Using “CMD” (DOS) I then searched to make sure there were no references to these files. I also emptied the Downloads directory. After this I downloaded and reinstalled Mach3 ant the addon and then checked the ini files to ensure that “Extrusion axis=”A” and I still have the same problem.
        Is there a problem using Windows 10?


      • Did you have Slic3r installed other than the mach3 addon? It seems that there is a path problem and Slic3r not using the ini files but internal default values or its own ini files. My suggestion again will be using the latest version of the add-on. Sorry for not solving your issue.

    I just downloaded a stand alone version of Slic3r and it works fine and is giving me the “A” prefix that I require. Using the setup facilities that are available on the main screen, there is a setting called “Printer flavor” and one of the settings available is “Unix/Mach3”. So I copied the entire contents in place of the Slic3r directory in Gnexlab. It still doesn’t work from within Mach3. At least I can use it as a stand alone slicer. I will still persevere with it though.
    You have mentioned installing the latest version of the addon. Where can I get it? on this website it is saying that version 1.3 is the latest?
