When 100% infil isn’t 100%.
So, lookie here and say “yeah, you need to double your stitching, or widenize your influx”
Or am I just supposed to expect gaps between the edges and insides of my prints?
Looks like the same problem I had. Turned out to be the filament extruder temsion. Measure 10mm of filament and extrude 10mm see if it matches, adjust your tension accordingly.
So when you extrude 10mm of filament, it’s 10mm unextruded filament? Not 10mm of the .35mm-ish extruded filament? (Things get a little unclear in Pronterface)
10 mms of source, yes.
Yes. Make sure the filament is pulled whatever distance you specify.
Yes mike, it’s 10mm of unextruded filament. As in the circumference of the hobbed bolt should rotate 10mm.

This should help, cleared up a lot of my confusion
I definitely understand the principle of testing extrusion with the hot end off. But now that I’ve spend my bot up I’ve been calibrating with the hot end on at print speed through repetier flow slider. I print a very large, very flat surface and adjust until I get the proper extrusion. That way if there is any slippage I am adjusting for it. Now my top in fill as smooth as ever.
Thanks guys, giving is a shot this morning, just as soon as the Coffee brews!
I’m finding the PLA swells really rapidly, and timing that with ‘leave the fan off for the first level’ is causing swelling before the system can get the pipeline going…sigh It’s easy to forget the 30 bugs I’ve fixed and it gets right every time when looking at the next bug…at the same time, hand feeding filament looks like it could lay down a LOT of it, FAST, and retract it enough to not be in the hot zone…the hard part is translating the hand movements into math.
Man this is seriously frustrating. I’ve got the e-steps calibrated. The filament being laid down is still thinner than slicer wants (IMHO) to be 100% infill. laying down 4 thin layers to check flow has the extruder plugging about 80% of the way through the print.
I can now see why folks want to drop money on a turnkey solution. I’m learning a lot, but I want to be done learning a lot. 
At what temperature are you running your extruder ?
205 or so. 190 and lower and there was zero adhesion. I’ve temporarily switched to ABS which is working differently (if not exactly better)…I don’t have a heated bed, but the build envelope is small enough that I doubt lifting will be a problem (or at leas not a larger problem than everything else)
So far with PLA i am running at 200.
Also cleaning the painter tape with iso alchool really helps for adhersion.
Yeah, I’m doing that. Honestly, things would be a WHOLE lot easier if I had a neighbor that’d already gone through learning the ropes.
FWIW, when using the alcohol, Rub HARD…you’re trying to rough up the surface and remove a layer…just a light rubdown doesn’t seem enough.
Lol I’m on the Montreal south-shore probably way far !
For the alcohol, I use those small pads they sell at the drug store for rubbing before injection.
@Mike_Miller , I honestly like ABS better than PLA, it shrinks like a mofo, but less dripping, stringing and blobbing
