3DP=End Of Me

So after numerous days of trying to get my 3D Printer back in order, I am still having problems.
It all started with a new spool of black filament.
The day before I was printing like a madman with only a few hiccups.
Change the spool and now nothing works as expected. Curled edges, bad lines, gaps in print.
Could a new spool really cause this much controversy?
My answer is Yes!
Same spool, same company..
How can one spool print fine with the doors open, zero bed temp and 210 degrees of fun...
while the next spool requires a bed temp of 100, doors closed and 240 degrees on the extruder?

It is almost like the first roll was made from a nice filament blend.. while the next one was made with old tires.
Go figure.
