I don’t know anything about that filament you’re using, but those gaps between perimeter and infill almost look like underextrusion to me.
I’ll read back on the history of this thread but did you calibrate your extruder? Out of the box most of the SM’s have been set a little on the low side for extrusion feed rate. It’s also possible with a fiber-included filament (I think you said this one has carbon fiber in it) that you just get inconsistent flow, depending on the distribution / quality of the filament production.
Edit - also what are your retraction settings? The default retraction settings SM provides are like 4mm or something crazy. Almost everyone here I’ve read recommends turning that down to 1mm and 40mm/sec speed (or less). Otherwise it’s starving the nozzle so much when it goes from finishing an outline to moving over to the starting corner for infill that it takes a while to ‘restart’. Those low spots almost all look like they’re in the same corner…
