Creazione nuovo profilo

[bren 0]

Ho creato un nuovo profilo da uno esistente chiamato "Normal"con Cura 5.1.0. Ho cambiato layer height, da 0.2 a 0.3, infill density da 20% a 5%, infill speed da 80 a 90 e first layer speed da 20 a 25, poi ho cliccato su "Create profile from current settings/overrides" ed ho rinominato il nuovo profilo in "Veloce". 
Pare tutto ok ci sono i due profili con i relativi parametri.
C'è però un problema, mi sono accorto che quando riutilizzo il profilo Normal originale i tempi di stampa sono pressochè raddoppiati ma non capisco il perchè. Al momento ho risolto il problema ricopiando la Configuration folder che avevo prudentemente salvato al sicuro.
Qualcuno può aiutarmi? Ringrazio in anticipo e buona stampa 3d a tutti.

If I understand the question correctly...

Your "normal" profile (infill 20%, Print Speed 20mm/sec, etc.) and your "Fast" profile is 25% faster print speed and only spends 25% as much time on the infill and only has 67% as many layers to print.

The main difference in time calculations is usually Accel and Jerk but if you have long slow retractions and primes, and maybe Z-Hops then those things take more time.  The geometry of the model may have a large effect also.

Perhaps this is not the question. I created the new profile. Then i have the previus and the new profile. Without any other change if i reuse tre original profile its print times are almost doudled. 

So the printing times of the original profile should have remained unchanged and not double. 

Where is the problem? is it a bug or i am doing something wrong?

Thanks

OK.  So "Profile #1" should be just as it was, but now the print time has doubled.  Something must have changed even though you did not make any changes.  If it changed by itself then it's likely a bug.

Did you unhide all the settings and go through them one-by-one?  Does anything stick out as being wrong?
