    Cura 2 misbehaving

    Hi

    First timer here so please be kind!


    I have just migrated from Cura V1 to Cura V2 (V3.2.1 Linux)

    Before you ask, I have designed and built my own 3D printer and extruder from scratch and am currently configuring it. Cura has been, by far, the stand out software package on the Linux platform.

    It's a RepRap, Marlin driven machine. It's well set-up and configured in Marlin and I trust it's capabilities. I have had a great deal of success using Cura V1.


    Info:

    I have been printing the XYZ Calibration Cube on a RAFT no problems in Cura V1, but now in Cura V2, it seems to print the RAFT no problems (approx 2.5mm of linear extrusion per 20mm of travel, according to the G-CODE) This prints great, but when it begins to print the first layer (of the cube) the extrusion drops to 0.3mm per 20mm linear travel (approx) which, obviously, completely ruins the first layer!!! (FYI, the G-CODE looks like it uses a very slow extrusion over the entire part although I haven't allowed the print to continue past the first several layers) This is also observed by watching the extruder, it's REEEAAAAAALLY slow!!

    I can provide images if requested.

    RANDOM SNIPPET:

    As you can see, 20mm travel is only producing (approx) 0.3mm extrusion... WTF???

    So, I guess my question is WTF??? And, has anyone else had this experience with Cura 2? Is it just a Linux thing? Is there a setting I'm missing??

    I've been through all the settings (I believe) and have not found anything that fixes this issue. The setting "Initial Layer Line Width" does have an effect on the first layer, but I'd have to make it like 1000% to get it close to what's required (which it seriously complains about) but I can't pin-point anything that is causing this.

    Am I just a serious NOOB or is this a knows issue??

    HELP!!!!!!!!!!???

    Thanks guys and gals!!

    Cura is on version 3 now. Perhaps the new version will work better?
    if you looked at the gcode and it looks right perhaps you should post it as a cura bug on their dev site?

      Thanks jsprenkle,
      I'm using version 3.2.1 (I was under the impression they were calling it "Version 2") I am using a Ubuntu version running on Fedora as a but of a hack. I'll get the latest GitHub and build that and see how it goes.
      Cheers mate!
