    Does anyone know how/have a guide to setting up an R1+ with Cura 2? I don't see a preset, and I can't find the settings for dimension, and g-code.

    There is no longer a preset, you need to select "Other"

    Check the Robo forum here:
    http://community.robo3d.com/index.php?threads/cura-2-1-beta.8319/

    You could also start with this for the Robo R1+. Even though it's for Cura ver 15.04, you should be able to enter the same settings into a newer version.

    I tried Cura ver 2.3 and did not like it, so I'm using ver 15.04.6 with the Robo R1+.
    Because I'm using Marlin 1.1.0-RC firmware (highly recommended as the MESH bed leveling gives me a perfect first layer every time), I had to change one line in the Cura start GCode because Z-offset is no longer set using M565. MESH bed leveling fixes such a fundamental flaw that, in my opinion, any tweaking of the slicer settings is not going to give optimum results without this new firmware.

    If you want to update your Marlin firmware first at the link below, I'd be happy to share my Cura 15.04 settings.

    Here you go.

    These are my settings for Cura 15.04.6 with stock Robo R1+ , LCD, and Marlin 1.1.0-RC firmware (November 2016) to enable MESH bed leveling.

    I'm happy with these settings and I'm getting consistent results. I print with PLA filament only.

    Notes:
    1. Layer height is 0.1 (Fine) Set to 0.2 for Normal.
    2. I like to use a Brim for part adhesion. However, the Brim setting in Cura also creates a brim around interior openings which make it harder to clean the part after removal. So, to get an outside brim only you have to trick Cura into building a skirt that mimics a brim. To do so, click on the ... next to None (where I've placed the red arrow below) and add the three setting in the Expert config box.
    3. I like to verify the extruder is working and wipe the nozzle clean before starting the print. I set up the Start Code to raise the extruder, extrude some filament, beep, and wait 6 seconds for you to wipe the nozzle. Then we home again and start printing.
    4. If you experience bed adhesion issues, you can experiment with the Initial Layer Line Width under the Advanced Tab. Note that I've left the G29 in the Start Code at zero. You really shouldn't have to change it.
    5. Be sure to save your Configuration Settings. Make a backup of your Configuration (.ini) file so in case you experiment with any settings you can always revert back.
