Printing issues with ABS on Stratasys FORTUS 450MC

Hello,

I have a few questions regarding some issues I'm experiencing on Stratasys Fortus 450MC. If any of you could help me, I would be very happy.

This first issue I had was with a large parts printed quite close to each other and what seemed to be the issue is this ''overheated'' like oozing and stringing. (Pictures1)

The second issue I'm experienced quite often are these zits and blobs. (Pictures2).

I'm using ABS-M30BLK with T16 model tip and SR35 with T12SR30 support tip.
All of these builds are done through GrabCad 3D with the following settings:
Part fill style: Sparse 18%
Variable width fill
Support style: usually Box or SMART

The operating conditions where the 3D printer is working and where the filaments are stored are stabilized between 19°-22°C and 40-55%RH.

Thanks for any suggestions.
