I would try changing the stepper driver, but the new board has everything soldered down. It would be no easy switch. Slowing the perimeters has helped a little.

I went higher on the extraction length, but it seems like the blob starts at the beginning of a new line, not at the end where the retraction would help. I'll try lowering the temperature a bit. That makes a lot of sense also.

I've been messing around with retraction settings. Even tried -0.3 on extra length at restart. Nothing seems to be helping that much. Extrusion and feed rate has been calibrated. Any help would be great. Thanks!

What values have you tried for retraction? When I was using the stock hotend, some filaments required almost 2mm of retraction to stop the blobbing. The other thing that helped was adjusting the temps lower by 2-3C. YMMV

I would suggest a search for this topic. 

http://www.soliforum.com/post/33374/#p33374 deals a little with the topic, but there are other threads that may be more helpful.
