So I recently took over an old Vyper from a friend. The hotend was pretty caked up so I bought a replacement one from Amazon along with Some hardened steel extruder.

When I tried running the printer with the old hotend and extruder, it printed as it should except that it leaked some filament from the sides, so I put in the replacement: after doing so, the filament will not stick to the print plate and gathers at the extruder (picture)

Has anybody else have had to deal with this and know of a fix? I have tried deep cleansing the print plate, changing temps and messing with the Z-offset, but nothing gives.

Any help is appreciated!
