    My prints have gaps in between the infill. My extrusion rate is turned down pretty low (I had to turn it down to get a first layer) but the calibration cube comes out perfect in size. Any ideas?

    What infill percentage are you set to? That could be a normal looking honeycomb infill if the percentage is low.

    What slicer are you using? Generally thats a slicer limitation. I find Cura handles those voids pretty well.

    I can't use cura because it doesn't connect to my printer with the cura software. Is there any way to import cura into repetier-host mac?

    And the infill percentage (not the extrusion rate) is 40%

    I think I 'get' what you are complaining about now. The (small) lines between the layers of the honeycomb.
    I agree with @Mike Kelly on that being a slicer artifact. Assuming normal layers (not infill) are going down correctly then that is just something the slicer is doing. Other than trying a new slicer you could alter the infill pattern from say, honeycomb to rectilinear... that might work better.

    Run bootcamp to use the latest version of Repetier-host that has cura support.

    A few things to clarify:

    The honeycomb is not the infill, it is just the pattern in that print. I used it as it was the best picture for showing the lines between the infill. It is the same on all infill types. I will experiment with 'infill extrusion width' sometime and let you know if that fixes anything.

    Just want to let you know that the problem is solved. It turns out I had set my nozzle size as .5 instead of .4. This is why I had to turn my extrusion rate down to 70% as well. Now with new nozzle size and 95% extrusion rate the gaps are gone and the first layers still look good.

    Thanks

    Nice.

    I had the sort-of the reverse with one 0.4 nozzle that was oversized enough (25%) that I just set it to 0.5 in the slicer to make up for it :)
