PID tuning with filament extrusion

[beny]

Hi All,
I wonder if it is possible to do PID tuning while extruding filament? Any one had tried such thing? Is it really necessary?
I print simple objects at constant flow, constant movement speed and with temperature sensitive filament. Any temperature deviations end up with visual artifacts on my prints. Currently I’ve noticed that the visual artifacts are more likely to happen on one side of my prints, so wonder if this isn’t some heat building up while extruding or PID oscillation.
The idea is that since while extruding there is additional cooling factor (filament), doing PID tuning while extruding should allow much precise results. What are your thoughts on this?

Thank you in advance,
Beny

Hello @beny !

Never heard of that practice.

@beny

Is it really necessary?

Who said that?

@beny

PID oscillation

If the PID tune went properly, there should be no noticeable oscillation.

The difference would be marginal, because that materials we print with have very low thermal capacity.

You may check if you may have some additional airflow from the surroundings.
