Better temperature and speed for PLA

[Gianfranco_Frag]

Which are the better temperature and speed for PLA?

I tried from 180 to 240°C, but if the temp is colder the PLA doesn’t cool down, if hotter it cools too much…so i changed the speed, but i don’t find the right relationship temp-speed, help help help thank you very much

Hi Gianfranco!
Maybe you must polish the nozzle, it can be obstructed.

It can be also a problem of the pusher tag block which must be regulated.

Let me know

Hello!
The PLA it can print at 210-215 ° while for the speed 35-40 mm / s .
With these settings it prints well, but depends on the quality of the PLA .
The only solution is to try , try and try again !

I print with a prusa i3 et direct drive MK8 extruder 0,4mm nozzle.

210 for extruder, bed at 65, speed between 60 and 130 mms, flow 105 %, fan 50 to 75 %

Blue tape with hairspray on heatbed.

That’S works fine for me

Thanks. I tried to print from 180C to 240C…180C it’s impossible to print even with low low low speed, over 200C i start printing but with low speed, if i want print at 80mms i must set the temp at 230-240C! Maybe i have to change the PLA? And the surface isnt smooth, but i see all the layers on the surface.
