Over extrusion on solid infill

Hi Guys,

I have recently purchase another spool of PLA material. I bought white PLA made by Verbatim and there is one thing I noticed while I changed the material on the printer.

Now it seems that it overextrude it on the solid infill (see picture below)

I have done the atomic cleaning before new filament and also tried the thin wall cube calibration. The conclusion is that is prints really nice perimeter (measured the walls of thin cube) but is completely rubbish on the infill (see pic). Do you know what might be the reason for that?

The extrusion of both perimeters width and infill width are 0.45.
Temps 200/60.

Kind regards,
Michal Uhman

Hi Michal

Two things to check. Firstly, ensure that the calibration is good; if the nozzle is too close, this is exactly the result.

Secondly, with a new filament, you may have to calibrate the feed. If the filament is slightly harder, then you will feed more filament, so carry out the following:

With the filament loaded and the extruder hot, measure and make a mark on the filament 110mm from the top of the extruder.

Feed 100mm (Pronterface/Octoprint terminal: G1 E100 F100 - this will feed (E) 100mm of filament at 100mm/sec (F)

Measure from the top of the extruder to the mark on the filament; if it is less than 10mm then you will need to reduce the flow rate accordingly.

I hope you mean 100 mm/min 😛

Very useful advice though! I will easily do this test next time I purchase a filament from another brand. Esun works fine as it is, but who knows with other ones.

Hi Sascha

Thanks for picking me up on that! We all make mistakes; me more than most 🙁 Apologies...

Still, as they say, if you never made a mistake, you never made anything...
