I started with PLA and prints were terrible. I played around all day yesterday with it. Long story short, I had to move to 170c temp to get good prints. things were better with 0.2mm, but anything less my posts grew trees on the sides! I did 2 posts each test, and started to lower the temps 10c at a time. things were improving at 190c. 180c I was left with the slotted part (top) over hanging the main sides a fraction. now 170c gives me perfect prints. I will get my IR thermal probe on the head later and see what temp its really at..rubber_jonnie wrote: ↑Tue Nov 20, 2018 8:38 am Just as a little bit of extra info, these print fine at .2mm, but at .1mm had some very fine stringing, and I know that exxos also had some print problems including stringing too.
.2mm is fine for most scenarios, but if you try to print finer and get stringing, then dropping the filament temp should do the trick. I was running at 200C, dropping to 190C or 180C should make it nicer. I'd also suggest perhaps printing solid rather than with infill.
Basically went from looking like these..
To these..
