Cons of using Infill before Perimeters?
Hi - newbie here - received my Mini+ last week.
I've been waiting on my prusament PLA (stuck with Fedex) and in the meantime I've been generating prints using my spool of PETG I bought in Canada. I've been successful with 3 prints so far - improving my first layer on each go.
So I started a bigger print - and I couldn't get the perimeter to stick consistently and once the infill would start I would get lift off and globs. I noticed on the print settings, there's an option to do infill before perimeters, and in my novice thinking I figured this would give my first layer more probability of success because there would be more "gravity" for each line, being that they each would have a neighbour to stick to, in addition to the textured surface.
I'm ~2hrs in and it's printing pretty well - no lift off at all from the infill and the later perimeter. Fingers crossed it will finish.
My question is - is there a disadvantage of doing infills before perimeters? Am I opening up another issue that I don't see yet?
Thank you!

Naw, experiment, be prepared to fail, it's how we learn. it's just a setting and isn't necessarily the reason your print is going well right now.
All the settings in slicer are there because of the infinite number of possible situations you may have to deal with as you try to print different models, what works on one may not work on another, experimenting is the best thing you can do, and it's fun.
ultimately you will have problems to deal with and everything you learn from this can and will be used later for some other problem, it's actually one of my favorite things about printing, I love the challenge of figuring out how to do it, and each time I get stronger.
Enjoy it, even when its kicking your ass.

RE:
I would just caution you not to start your printing career by applying kludges instead of fixing the underlying issue. As swiss_cheese said, experimenting is good. But if you
couldn't get the perimeter to stick consistently and once the infill would start I would get lift off and globs.
then more likely than not your live z is not dialed in well enough and/or you haven't cleaned your sheet thoroughly with soap and hot water.
Sure, maybe playing with infill before perimeter may help you in this situation but unless you tackle the underlying cause of the problem, it'll pop up elsewhere down the road.

Hi @fuchsr, I have been reading all the wisdom on printing with PETG - 3 of my smaller volume jobs printed no problem without this set. But when I attempt to print the larger part, nothing seemed to work until I flipped this switch. Interestingly enough, when I next printed a small job, I had to unselect it. In fact, as I'm writing this, I have just starting printing 4 t-nuts with the setting off and they went down no problem.
My suspicion is that my bed is not level - I'm looking for the parts for the silicone mod so that I can tune it in.
In the meantime, I just wanted to make sure that this "kludge" didn't create new problems for me.
