So I recently decided to try to print with a smaller nozzle diameter but I have run into a problem.
The filament extrudes somewhat out of the nozzle but after each extrusion step, there is a small thud sound and the filament looks as if it is being retracted.
I believe this is caused due to too much pressure building up in the extruder throat.
I have not had this problem with a 0.4 mm nozzle.
What could be the problem?
Are there any specific settings that must be changed to make it work?
