Troubleshooting rough details
Did my first print a couple hours ago. Hurray! Most of the model looks awesome!
But there are some parts, which could use quiet a lot improvements:
Already removed some of the stringing but this is not clean enough for printing miniatures ...
The dome suddenly started to get rough on one side and then slightly got better with each layer ... maybe the pointy needle caused this due to the high amount of stringing?
Also those sloped pillars look horrible ...
I read a lot about adjusting temperature and stuff, but I'm not experienced enough to take advantage from that literature 😐
Any help would be appreciated 🙂
I use the default Slic3r settings from prusa:

Re: Troubleshooting rough details
That is a good torture test print, but to troubleshoot individual problems, try a smaller print for each that will print in 10-15 minutes and show one problem clearly.
Chase one problem at a time and change one setting at a time. Otherwise you'll chase your tail as one fix causes another problem elsewhere.
Most of all, get your 1st layer right. That's literally the foundation for the rest of your print.
Re: Troubleshooting rough details
1st layer is fine and in general no shifting/drifting/skips and so on ... only issue is this accumulation of filament on smaller details which are close together and i would like to fix it. Not sure if this is related to stringing in general and what the best approach would be to fix it.
Re: Troubleshooting rough details
So i tried to get rid of stringing, but i m not able to ... most ppl suggested increasing retraction, so I increased it: 0.8 -> 1.5.
This just added underextrusion, but did not affect stringing ... what to try next?
