I read that.  I'm not talking about a 30% change as a permanent fix.  Going from 100% to 105% when changing a material is acceptable to me.  If you were to print a lot of PETG then it might be worth re-calibrating.  For a few prints, and if the percentage is low, then rather than re-calibrating every time I changed spools (necessary if they spend time sitting on a shelf absorbing moisture) I would just tweak the flow rate.  Some folks will no doubt consider that quick-and-dirty.

 

There are arguments both ways regarding calibrating with a "single wall cube" versus a "double wall cube".  Good luck.

 

thank you for the support. Do you suggest to use a single o double wall cube? Thank you.

The best way to check is to adjust the flow during a print using the LCD control.  Once you get it dialed in to an acceptable percentage then you can change all the flow settings in Cura to that number, and save it as your PETG profile.

II don't know if it's a slightly different diameter of filament, different coefficient of expansion, or what it is but there is an effect there that makes it different than PLA.

thank you for the reply. I read on the Cura settings support that "modifying the flow in order to solve the underextrusion, is not a definitely a solution". In any case, I would to print a single wall cube in order to understand if the flow is ok or not.

Hello, this is my first time that I'm printing with filoalfa PETG, but I noticed an underextusion with 100% of flow. The width and height settings are the Cura default. How can I improve or solve this kind of problem?
Thank you.
