If I use PLA settings it comes out stringy and doesn't adhere well. Apparently 190C isn't enough to melt the PLA sufficiently. But all is ok if I use ABS settings. This is with filament that I used before with my old original nozzle and it worked fine. Note that my old nozzle must have been very worn out (I print with Carbon Fiber and Wood infused as well as metal infused filament a lot). My Mosaic PV number for the calibration print went down by about 10,000 mm with the new nozzle indicating I'm using much less filament - about an 8% difference. I guess it's livable, but has anyone else seen this?
