I know problem when lower layer of ABS is wrapping. With insulating bed I have no wrap of lower layers. Bed keeps plastic very well and strong.
So, problem with higher layers - it's wraping as on screenshot, so my extruder strikes it and moves after long work on supports.
But around supports seems not wraping at all ! Why ? What I'm doing wrong ?
I rised ABS temp by 250, made walls(forgot right word

It helped me alot but result still isn't perfect.
So, I have 2 questions:
1. Why every tutorial suggests low down plastic temp as much as possible(210 for ABS). Noobe explains why I should do this.
2. What I doing wrong ? How to eliminate that wraping on picture during printing process ?
Thanks for any help.
