Question

Team, I recently finished my V 2.4 with Stealthburner and immediately began printing getting pretty good results. As I was going through the process of tuning (Voron/Ellis), the first layers went to crap bad enough that I can no longer print. I have taken the toolhead completely apart twice and found no obvious issues. It still looks new.
Following extensive inspection and testing I have concluded that there is a problem with the nozzle. As it begins to extrude, the PLA curls back on the nozzle eventually creating a ball of plastic. It looks like that ball of plastic contacts and rips up the first layer (see second photo). You can also see on the second red patch that it appears that the flow of plastic is insufficient in that it is necking down?
I know very little about printing plastic and would appreciate some help.
As part of the tuning process I have played with the Z offset. It hardly makes a difference as I adjust the value.
The extruded plastic should exit straight down? Is the nozzle partially clogged causing the curling? If yes, how do you suggest I clear it? 0.4 mm drill?
Thanks all for your input. In the meantime I am going back to square one and repeating the initial startup procedures.
Edit:
Bob
