messing around with Cura 2.5 i decided to try to push the soeeds on the C2. 125mms for walls and 150mm/s for infill and supports. Now rhis was with Hatchbox white petg needless to say it wasnt the best but i started fine tuning it. I started at .3mm layer height and it wasnt i would say horrible but for sure not that good. After changing settings and doing about 10 different prints i was able to get an acceptable print out of it. I will post pictures later of each setting for each print and you can give your 2 cents on it. I was however after changing the layer height to .2mm and speed for walls to 75mm/s with infill and supports at 100mm/s i got a print i was satisfied with given the layer height and it cut down the time from the standard Robo profile for .2mm layer height from 2.5 hours to 1.25 hours and it came out pretty good compared to the original profile. Now the only issue i have found is at these speeds it seem that the supports are for some reason harder to remove so i am still trying to get that figured out. Also this is with petg which is harder to print with at least from my experience with PLA. Who else has pushed their C2 to the limit and how much time were you able to cut down?
