Blobs of plastic
I am getting blobs of plastic on my prints. I bought new nozzles and have been trying to reset my Z for the last 2 days. This printer is about a month old. Printed for the first 3 weeks almost 24 hours a day with great results. Now I can't get rid of these blobs of plastic. I printed the Skull that came on the sd card and it had about 8 or 10 round blobs about the size of a BB. Please help.
Your filament is damp and I'm fairly sure your nozzle is wrongly inserted.
Check: is there filament oozing from the top of the heater block?
If so, pay particular attention to the diagrams at the bottom of this page:

Cheerio,
RE: Blobs of plastic
The Benchy was wet filament but I have tried several different filaments and still get the blobs of plastic without the strings.
RE: Blobs of plastic
As diem said, most likely your nozzles are not properly inserted or the heartbreak got unscrewed vis-à-vis the heater block when you swapped nozzles.

I pulled nozzle and clean everything up. I guess I didn't tighten the new nozzle tight enough. Seems to be working good on the first layer print and first layer test. Now to print something and see if its good. Thanks
