Just got my Creality 10S and while using the supplied PLA it printed fine and had good bed adhesion. I was printing Rick Sanchez one night and the roll came to an end but it had a bend in it which caught on the filament sensor and ran for half the night like that not printing anything of course.

I got some Matter Hackers MH PLA and now it's printing really thin and brittle and I can't even get it to adhere to the bed. I replaced the nozzle with an upgraded one from MH and closed up the gap between the head and the teflon feed tube and cleaned the feeder knurled wheel but it's still goofing up. I tried 200 head temp and 70 degree bed temp.

I have noticed when I print a raft the first outer line it lays down is missing. It starts printing about half way around.

Is there something wrong with the MH products?

Could I have messed up the stepper that feeds the filament?

Is there a software that lets me control the z axis and the filament feed to see if it's got problems feeding? I'd like to raise the head and flow it out.

Thanks in advance!
