Guys, I promise you are not alone in trying to figure out why your machine that used to make beautiful prints suddenly cannot manage to get the infill to meet the walls on simple boxes.
It is 1:30am here and I am reading your posts and trying everything and testing and doing everything I can and getting the same results you are seeing.
Something is wrong in FLUX Studio or all of our machines are collectively wearing out at the same time.
I wish I had answers but I don't at the moment. I'm trying everything I can. My old faithful leaky printhead died. The new (rebuilt) one I just got back from FLUX a few weeks ago is already melted and starting to leak, and I'm struggling to get any kind of consistency in good prints.
I get one good one from FLUX Studio, then it goes to crap for no apparent reason. I switch to S3D and it works great for a print or two, then just turns to a mess. Then I switch back. No consistence at all. I'm currently in the middle of the 'pancake' testing that was written up in another post.
Needless to say, I am extremely disappointed too, and I don't have any idea what to do to make this machine work like it used to.
If the pancake test and remedy works for me too, I will post again.
