Ultimaker 2 over extrusion

[evostatic 0]

so when i print with my um2 it seems to slow down momentarily then spew out more plastic than normal.it causes bulges and unevenness any tip? also the plastic beads up and looks like little drip marks instead of one solid line. the extruder is not clicking or skipping.

Slow down when? Pictures would be really helpful.

Video would be even better.

the drip in stead of a 'noodle' can often be either the start of a blockage and/or a dirty end of nozzle - I always give mine a wipe when it is hot and then run a bit through - sometimes the noodles shoots off sideways so I wipe it a bit more until I get a nice straight down noodle.

warning - nozzle is hot

always worth doing the gr5 nuclear clean!

It's called "atomic method" because it was first mentioned by "mostlyAtomicBob" on this forum. On other forums they call it "cold pull".
