    So the 1.75 is probably easier to melt, but the 3 is more consistant to feed?

    The consensus on 3 vs 1.75 is that 1.75 require less pressure to extrude.
    This means there is an advantage with weak or direct drive extruders.
    IME it also requires less pressure from the rollers in the extruder which means you're less likely to get stripping or slipping.

    The reason everyone still uses 3mm is until recently it was a LOT cheaper and in some countries it still is, I was recently told that in the UK 1.75mm is 3x the cost per pound vs 3mm.

    There is also a lack of well regarded hot-ends designed for 1.75.

    As to all the configurations, you guys are way more organized than I am.
    I just have 2 one for PLA and one for ABS when I swap reals I change the temperature and the volume multiplier in Slic3r.
    I usually use a real before swapping, so I have to calibrate again anyway.

    Once I hobbed my roller, slippage is a thing of the past. 3mm seems to feed and perform just fine. Well as good as I was getting with the 1.75 LOL.

    I think we have the same kit, never had any issue of filament jamming with that. And it’s also because I use quality ABS and PLA filaments. I must say PLA filament is very versatile; all 3D printers on the market can accommodate this kind of material.
