Raise the nozzle 50-70mm off the bed and extrude 5mm of filament. Does it curl up? It should extrude directly down onto the bed with little to no curling.
If it does curl, the nozzle may still be partially clogged or the exterior may be dirty. Given the low bed temp, I'm assuming you're using PLA. SCIGRIP 4
solvent is known to dissolve PLA... like Acetone dissolves ABS. Disassemble and soak the nozzle overnight.
As a final (optional) measure, thread a strand of wire through the nozzle to ensure its clear... .2 is very fine. Maybe a few strands from multistranded connecting wire will work. But may not be stiff enough to clear any blockages. Do no stick a solid object like pin tip in the nozzle... it could damage it.
Hope that helps.
