    Hello there I have a Robo R1+ and I would like to use cura but from old forums it seems as though the advanced settings and such are gone. It looks like the leveling is off and everything. Does anyone have a walk through to create the settings for our printer?

    Did you ever get this working? I downloaded the 2.5 from Robo's site, but when I try to print with it the extruder moves to the back of the build area and makes a horrible grinding noise before starting to extrude in mid-air about 4 inches above the build plate.
    Highly frustrating.

    I believe that 2.5 is for the r2.

    Id check to ensure the r1+ is set as your machine. Last i knew there was not a profile in cura 2.x for the r1 series. Whats the start up script.

    It is set as my machine. The start gcode included for the R1+ seems to be the problem. I replaced it with another set I found on these forums and that seems to (mostly) work. Should I submit a bug (somehow) to Robo to fix the start gcode being packaged with their Cura build?

    You could ping their support and let them know it's incorrect for sure. Not surprising as they only built their flavor cura for the new line machines, guess they added the decommissioned R1 series as a "convenience" for those wanting it

    @Jason Hough Can you check one thing for me? In the Robo R1 profile what is the build dimensions, they sound like they are just a bit over what the printer is actually capable of doing.

    Sorry for the delayed reply, @WheresWaldo

    It has these settings in the provided profile:
    X: 225
    Y: 245
    Z: 210

    I don't recall that Y axis is actually that big, since they do not have software max endstops activated it can actually try to go past the end if you ask it to.

    The maximum I was able to get with a stock R1/R1+ was:

    X:220
    Y:236
    Z:230​

    Jason, can you post your Gcode? I'm setting up Cura for my R1+ and am having the same issues.

    Unfortunately I can't confirm these work because my printer is non-functional right now, but you're welcome to try them:

    Start Gcode:

    Code:
    G21 ;metric values
    G90 ;absolute positioning
    M82 ;set extruder to absolute mode
    G28 X0 Y0 Z0;move X/Y/Z to min endstops
    G29 ;run auto-level routine
    G92 E0 ;zero the extruded length
    G109 S{print_temperature} ;set extruder temperature and wait
    G190 S{print_bed_temperature) ;set bed temperature and wait

    End Gcode:
    Code:
    M104 S0 ;extruder heater off
    M140 S0 ;heated bed heater off (if you have it)
    G91 ;relative positioning
    G1 E-1 F300 ;retract the filament a bit before lifting the nozzle, to release some of the pressure
    G1 Z+0.5 E-5 X-20 Y-20 F{speed_travel} ;move Z up a bit and retract filament even more
    G28 X0 Y200 ;move X/Y to min endstops, so the head is out of the way
    M84 ;steppers off
    G90 ;absolute positioning

    Ive had the same issue where the standard Gcode that comes with Cura 2.5 for the Robo R1+ runs fine but then when it prints it prints about two inches off the build plate :/.

    G92 E0 ;
    M565 Z-0.9 ;
    G29 ;

    I tried the Gcode that I use on cura 15.04.6 on Cura 2.5 which is:

    M104 S{print_temperature}
    M190 S{print_bed_temperature} ;preheat bed and wait
    G21 ;use metric values
    G90 ;use absolute positioning
    M82 ;set extruder to absolute mode
    M107 ;start with fan off
    G28 X0 Y0 ;home X & Y
    G28 Z0 ;home Z
    G1 Z5 F5000 ;lift nozzle 5mm
    M565 Z0.8 ;use 1.0 Z-offset
    G29 ;run autolevel
    G1 Z15.0 F9000 ;raise nozzle 15 mm
    G92 E0 ;zero the extruder
    M109 S{print_temperature} ;wait for nozzle to heat
    M117 Printing... ;print message on LCD

    and the printer does everythung right it autolevels, warms up the extruder and the bed then when it reaches the temp it starts to cooldown and never starts the print. Its odd because this same Gcode works fine on Cura15.04.6 .
