poor first layers
The first layers of my prints have started to become bad. The filament gets out by smoothly. Strange thing is that after a few layers, everything is ok.
DONE Hypothesis: dirty inside of nozzle?
Used cleaning filament -> no change
DONE Hypothesis: printing bed too cold?
Warmed it to about 30°C before printing -> no change
DONE Hypothesis: broken fan?
Changed the fan -> no change
DONE Hypothesis: buildtak too old
trying with a new one
The result is much better :-)
NOT_DONE Hypothises: dirty outside of nozzle: not conducting the heat well?
May be it needs to remain hot for some time for the whole nozzle to have a stable temperature.
NOT_DONE Hypothesis: remaining soap in the printing bed changing the physical properties of the filament?
NOT_DONE Trying to reproduce the error in a controlled fashion
I will try with this model.
