And another example... Left is the best I could get with a simple 20mm cube and slic3r playing with it for weeks. If i increased the extrusion factor it would print out of calibration, and after recalibrating I'd be back to the gaps. Right is with SFact...

+Jarred Baines  a lot of what is in that link may have been true in early designs but as calibration and slicers have improved it has become less relevant.  While it is true that using a hobbed bolt necessitates calibrating e-steps to ensure you are getting the proper amount of filament that is called for, once that calibration is done you really don't need to be messing with it and reflashing your firmware for each filament change.  The reason measurement is needed in the first place is because the accuracy of the hob is different from bolt to bolt.  The differences in how PLA, ABS, nylon, etc. are gripped are negligible.  It is better to set the proper amount of e-steps, using a long enough extrusion to mitigate error and then use proper measurement of the filament for input into the slicer.  You can tell that there is something set wrong somewhere by looking at the photo. Some slicers can seem to "smooth over" errors but that only masks the underlying problem.  If the printer's extruder is calibrated within a few steps then there is a good chance that something in the slicer is set wrong.  The only other option is that the filament is outside of spec.

Skeinforge is just suffering from a lack of love. For its vintage it is a great program but others have overtaken it in some areas. I still use it for 90%, or more, of my printing because of the flexibility it offers.

The only gripe I have with the printrun suite in general (and other 3D printing technology) is the choice of Python for the implementation.

Some handy tips in here. I'll admit that the one I don't stock is fresh lemons... Might have to change that.

Still playing with sfact/skienforge...The 50mm calibration tower without cool on the left and with cool on the right.

Just tried skienforge (sfact) and got great results... Dimensionally better than slic3r, smoother layers, too. Only weirdness is this gap in every layer... Any suggestion? It doesn't show up in the Gcode paths...

Yeah...
Clip is a fudge-setting... Clip will only work in your favor if you have retraction dialed in incorrectly or a similar problem (that should be corrected rather than turning on clip).

It's colder on the inside! Check out this incredibly chilly TARDIS sculpture made entirely out of ice!
