    Hey there Robo peeps,
    I’ve been looking all over the Robo forums for assistance to get my new Robo R1+ up and running but I’ve been having some issues. I found a starting gcode I would like to try out on S3D which I prefer to use over any other software. Truly the only issues I seem to be having are that I continue to have gaps in my top layers, and the infill inside just looks terribly ugly and misshapen. Also my nozzle on previous starting gcodes would heat up as the nozzle was touching the bed which I don’t think is a good idea at all. I slowed prints down to about 30.0mm because anything above was causing layer shifting.

    Well, what is the first problem you want to solve?

    I'd like to be able to fix the layer gaps! Thank you Mark, it's actually YOUR Gcode I'm going to try to use.

    So how many top/bottom layers have you set the process for and what layer height are you using?

    I like to have at LEAST 1mm of "shell on most all models (top/bottom/sides) since a millimeter is not a lot of plastic.
    I use more on models that need more strength.

    I currently print at a 0.2 layer height with my robo printers and usually at 4 top, 4 bottom and 2 outline layer I believe. I’m not in front of my pc right now but I’m positive that’s what it’s at.

    So that gives you less than 1mm of shell around. I'd suggest bumping those up to get > 1mm for a start.

    Understood, I was under the impression it was too much to be perfectly honest. What would you think would be a good number, or better yet what would be too much?

    Oh perfect, thank you very much! I’ll definitely take a look at those. On every other thing I was hoping you could maybe solve for me. I’m trying to set my starting gcode to have the nozzle wipe a line across the Y axis at the edge before printing.

    You need to see if you slicer is expecting the GCode to start in relative or absolute positioning (I think most use absolute) but regardless you need to know which.

    Assuming your slicer uses absolute then something like this?

    G91 ; use relative positioning for the XYZ axes
    G92 E0 ; zero the extruded length
    G1 Y100 E12 F600 ; move Y-carriage 100mm while purging 12mm of filament
    G92 E0 ; reset extrusion distance
    G90 ; use absolute positioning for the XYZ axes

    If your slicer uses relative then you can remove the G91 and G90 lines
