Bonjour à tous

voici le problème que je rencontre depuis quelques jours sans trouver de solution

Le rendu de mes impressions n'est plus brillant mais mat (voir photo des deux pièces cote à cotes)

Sans raisons apparente ou changement de réglage est apparut progressivement en 1 semaine

@neotko ?

 

The only reason I know to change pla gloss is temperature vs speed. For example on faber and fillamentum a 10C difference makes matte or gloss effect. Other than that, the speed even at same temperature also affects.

My theory is that pla if doesn’t reach certain temp (temperature depends on speed and how much time it really reaches that point inside the hotend) the plastic goes matte or gloss. So, do that 2 prints where done at same speed and temperature? Nothing changed? Spool/Nozzle/heater?

C'est étonnant quand même?

Au cas ou, tu as essayé un ancien gcode?

La température est bien stable et correspond à ce qui est demandé?

La température semble correct et stable mais tu as raison je vais essayer un ancien gcode

Remember that temperature, isn't linear. For example if the print area has many retractions, the filament stays longer on the hotend, so more filament reach the temperature, but if the area is constant extrusion less material reach that temperature, so the gloss/matte is easier to control. Basically... What you did on the gcode shows that indeed :D
