First layer problem with a large print
Hi!
I´m having troubles with a large print, the first layer always gets messed up (see attachments) in the middle of the bed. The strings won´t stick to each other or the bed. I think the Z-height is fine. I tried smaller prints and the first layer is perfect.
I clean the bed thoroughly with 99% IPA and weekly with acetone. PLA and the standard settings in Slic3er PE.
Tried to print this about seven times but I get a similar result. Any thought on whats the problem here?
Thanks!

Have you tried slowing layer 1 print speeds?
Re: First layer problem with a large print
I'm experiencing the same results with MK3 if base is large area.
So far, I didn't figure out what is the cause.
The fact is that the print table has different temperatures on the edges and in the center. In my case the difference is 10-15 C
Also, I noticed that the results are different with different filaments. Even the same maker, but different colour.
With the problematic fillaments I tested different temperature settings of the nozzle and the bed, but it had no effect.
I wonder if anybody got deeper/futher in investigation of this issue......

Same problem: 30x30 square prints flawless, 100x100 has peeling lines in the center.
Tried playing with bed level correction values, no luck. Wrote to support, no answer so far.
