How to migrate custom machines, profiles and materials from Cura 2.1 to Cura 2.3 ?

Recommended Posts

The title says it all.

Cura 2.3 ignores all machines, printing profiles and custom materials I have in my home directory in .cura and the directory structure inside the Cura.app MacOS executable is very different.

I tried to set up a new "custom FDM printer" using the new GUI dialog for that but

* most settings are not in that GUI (e.g. disallowed areas)

* it asks for some "printhead settings" with X+Y min+max but doesn't explain what that refers to and the "online documentation" doesn't work in Firefox on MacOS as it loads without any stylesheet and is thus unusable.

I can no longer make a "nozzle size" setting visible. With an Olsson Block on my Ultimaker II with Reprap G-Code flavor (to run it via Octoprint) I often swap nozzles.

Custom machines need to be migrated by hand. Sorry. All machines that were contributed to the Cura repo have been upgraded (even the non-UM ones, because we had to break API and we're nice like that!)

Note that 2.3.0 still has one known issue;


Known issue: Cura 2.1 profiles created for Ultimaker 2(+) printers on Mac OS X are not automatically copied to Cura 2.3. This issue will be solved shortly with the Cura 2.3.1 release. Please check this blog post for a workaround while the solution is being developed.

If you want an easy way to make your nozzle sizes visible; select the UM2+ and use that. As long as you don't do a firmware update using that, everything works just fine.

The produced G-Code for the E axis is in mm, isn't it? So the geared down extruder in an UM2+ make no difference when the produced g-code is executed on a UM2.

I don't see a way to export machines and materials in Cura2.3, so I guess I have to do this on MacOS and then again when I switch from MacOS to Windows?

      A: Materials which are hard in a solid piece (like metals, ceramics and carbon fibers) will generally also wear down the nozzle. In general one should assume...

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
