New Question:
3) When I print something my settings that make sure there is no underextrusion also cause my print to stick to the raft terribly. I believe I might be overextruding a little, 107% flow, but anything less causes underextrusion. I print with rafts to ensure that mass producing parts stick well to the buildplate when I'm not there.
First I tried to increase the airgap up to 0.5mm, which was definitely an improvement!!! But still there were parts of the raft sticking to my print. Then I figured out that with the Tweak at Z plugin I could start with a low flow(100%) so that the raft will be easily and after the first layers of the object tweak to 107% again.
The question is actually twofold, 3a) How would you normally improve the removability of the raft? I believe my method of high airgap is not really the way to go...
and/or
3b) When I use the print one at a time option how can I make sure that each raft+first layers is printed with 100% flow, and the rest of the part with 107%. When I do tweak at layer I would need to define all start and end layers(time consuming). Is this done automatically when you use the height tweak? So it would start with setting A, until 2 mm, then use the tweak at height setting B for 2-80mm to finish the part. Then start with setting A again for the next part, until 2mm, before using the tweak at height setting B again for 2-80, etc?
The short term solution is to use print all at once, then I know it's printing like it should, but I kinda dislike the option since it puts everything closer together and curls up rafts easier somehow and gives stringing.

RE 1) Strange, it always reloads the same for me no matter which format I use. Hopefully someone else knows
2) You can't set the order but cura knows how not to run into the other parts. However, it only knows that by what you tell it as far as the head size goes so yes if you are using a different fan shroud you need to update the values. Note that if any part is higher than the gantry height setting, cura will force "Print all at once" where all parts get the first layer then all parts get the next layer and so on. Otherwise the smaller shafts would potentially hit a completed part.
