Brim is not consistent
Hi, since ASA needs more adhesion, I print it with 10mm brim. The problem is that about half of it looks ok, but then the half which is closer to the part is basically individual strings

It seems to me that either something happens with the extrusion width or the z-offset increases and the strings are printed in the air...
Some ideas why this happens and how to fix it??
This is also visible on the back of the print
you are underextruding
and/or not close enough to the bed
main part is lifting, thats why it pulled the brim up
No, it first prints the brim, then the part, obviously. The part then warps up, because the closest threads of the brim are not sticked together
The question is why the brim is inconsistent?
no, well sorta, the part lifts up because its less extrusion than the brim.
you probably use 100% brim extrusion and like 93% for walls/top/bottom
the part in the middle lifts as a whole
because its underextruded
taking the brim with it
you see that because the whole actual part is not extruded properly
no squish in the middle
or on the edge of the main part
It is not underextrusion.... yesterday I tuned the EM. See, the brim was just fine
What I am afraid is that the z-offset changes....is there a way to print out to the console the value of the z-offset during the printing of the brim? Let's say every 30 seconds
Juhuuu, problem solved - parts printed wonderfully 
The problem was...the slicer! Initially I used SS version 2.5.59.0 and you can see through the brim
Then I sliced the same objects (without changing anything!) with an older version 2.4.58.5 and it worked - perfect first 
I think I will report the issue to supermerrill

What happened? Problem description: During the printing of a wider brim (10mm) the extrusion is reduced suddenly and the plastic threads do not stick together anymore. As this happens in the vicini...
Nice work! Thanks for sharing!
