Ultimaker UM2+ faulty printing from Cura

Recommended Posts

I have a brand new UM2+. Aside from some freezing of the firmware during setup it has printed from the SD card very well.


However, I have no card reader so I wanted to print directly from Cura 3.4.0.


Instead of heating up and raising the bed, the printer immediately starts to print in the air in the corner.


I updated the UM2+ firmware and updated Cura to 3.4.1. Same problem.


Below is a link to a short video showing the issue.


UM2+ not printing correctly from Cura


Am I missing a setting or configuration somewhere? The "machine" is correctly set to UM2+ and the material correctly set to PLA.

Well, apparently the default setting for G-code as "Ultimaker-2" is wrong.


After my question yesterday I tried to figure it out myself since I had no responses.


I uninstalled Cura. Restarted the computer. Reinstalled Cura. Restarted the computer. Updated the firmware again. The problem remained.


I then discovered if I home the printer and preheat the nozzle, the unit will start to print OK, albeit with poor quality.


On a hunch I changed the G-code flavour to "Marlin" and it is now printing directly from Cura.


Is that the correct setting for the UM2+?

I would argue that Marlin gcode flavor is the better option regardless of whether you print over usb or sd, but if you want to print over usb it is the only option.


In my opinion UltiGcode was an interesting idea at the time, but it did not really stand the test pf time.

    • "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.
