I had provided a link to thingiverse where I explain there how to proceed,. anyway I'll put here an extract from that I published there.
The solution I had conceived consist in a zip file having a set of definition (json) and configuration (cfg) files whose has to be copied accordingly into the CURA 4.2.1 installation directories; after that, when we restart ULTIMAKER CURA and we intend to add a new 3D printer it will include, below its “Add a non-network printer” list, a radio button for CreatBot-DX as choice.
Once installed, CURA 4.2.1 stores all predefined 3D printer settings into a “resources” directory at the installation directory, by examble usually in Windows it would be in this path: “C:\Program Files\Ultimaker Cura 4.2\resources”. Below this path we’ll see several directories, but those which matter for what we needed, are:
• definitions - contains the 3D printer definitions (json) files
• extruders - contains definitions (json) files for each extruder set.
• meshes - contains the 3D representation (stl) files for the building beds
• variants - has configuration (cfg) files to define HW variations (e.g. nozzles sizes)
• quality - has one directory per 3D printer with predefined quality profiles (cfg files)
• materials - contains per printer or generic predefined filament material profiles (xml files)
The attached “CBDX_resources.zip” file contains 6 directories with these same names, so what we have to do after extracting them to a temporary folder, is to copy the content of each of these folders to its homonymous directory in “resources” at the CURA 4.2.1 installation path (e.g. “C:\Program Files\Ultimaker Cura 4.2\resources” if Windows). The Quality profiles I had provided have very few parameters predefined, the idea is to use them as starting point to elaborate others more complex.
Once these files are placed in their CURA respective directories, the next time it’s started it will let available able CreatBot-DX as selectable 3D printer under “Add a non-network printer” category, just choose it and press on the Add button.
From this moment the Creatbot DX bed is shown (like in 2nd. picture) and we can operate over, like any other supported 3D printer, taking all the powerful advantage CURA 4.2.1 offers, of course obeying allays to the HW limitations of this 3D printer. Machine Settings can also be modified according the different DX series options.
When a new Ultimaker CURA be released, if they do not include these settings files there, we’ll need to update into all the respective Creatbot “.cfg“ files of this set, the “setting_version” parameter to the right number (possibly setting_version = 9) then once installed the new CURA version, repeat the copy procedure defined above. Hopefully someday Ultimaker team may include these or other even better settings to include CreatBot DX 3D printer so we don’t need to proceed in this way every time a new release arrives.
Definitions for Cura 4.3: Since Cura 4.3 was released recently, I added in this post a new zip with the respective CreatBot DX definition files. So you have to proceed in same way over the CURA 4.3 installation directories.
NOTE: Since you hade a DX2, in your case, once you finalized the procedure described above, you have to configure in Cura (Settings » Printers » Manage Printers... » CreatBot-DX » Machine Settings) the value of Number of Extruders to 2, just that.
Let me know if you get success configuring your Creatbot DX2 in CURA.
