From the infield to much heat?  

From the infield to much heat?

Hello,

...I'm a newbie - printer novice... ..MK3

I just made my first printout with ASA... should be similar to ABS.

(Are Thai letters.)

At the beginning I was very enthusiastic about this big piece.

Only when the upper layers of the yellow color have gone it looks like this now:

Had taken some pictures in between.

Also after the last color change:

Printed with 255 C extruder and 110 C heating bed.

Now this air heat bridge could be responsible for the smearing of the upper layers in this oval curve?

....and how do I get this handled?
