<p>I purchased new PLA, and from the first print, the wall layers will have little gaps in them but only &quot;just before&quot; (depending on the size this can be half an inch to a couple of inches) the Z seam. I thought it was a new PLA problem, nope, did a temperature tower and different shape prints, flawless.</p>
<p>It seems to be only my models that I make in Fusion 360 (I haven't tried downloading other people's models to see what happens) and slice in Cura that mess up.

<p>I have a VoxeLab Aquila which I use together with Ultimaker Cura. I print in PLA at 210 °C. Bed temperature is 60 °C. I use a print cooling fan at 100 %. The layer height I set to 0.3 mm, the line width 0.4 from the 0.4 mm nozzle. The Printing Speed is set to 30 mm/s for walls and 50 mm/s for infill. My retraction is 4 mm/off at 35 mm/s.</p>

Check that you do not have "coasting" enabled in your Cura configuration. I'm not sure where you got the profile for your printer, but at least a few of the printer profiles that ship with Cura have this (very harmful) misfeature enabled by default.

# Layer separation before Z seam on VoxeLab Aquila

Two things:

1. Check the STL file once you have exported from fusion360, sometimes stl files from fusion360 needs to be watertight one. In this case, yes, some models might leave a gap.
2. Check if nozzle is clean, sometimes partial clog can cause this issue too.
