Surfaces under supports not well defined. (Noob question)
Assembled my Prusa i3 MK2 kit and have had my printer printing for about 2 weeks. Problem I am having is that surfaces printed over supports show every pass and look very stringy (i.e. every head pass is highly visible and very rough.) Also support material is hard to remove. (using Natureworks PLA http://www.natureworksllc.com/Product-and-Applications/3D-Printing ). The PLA was supplied by the company I bought my kit through. (The Voxel Factory in Montreal, Canada)
Can someone point me to some setting for Slic3r settings which I can change to improve surfaces being supported (i.e. closer support spacing etc.) or will my problems disappear with the new beta version of Slic3r that was posted about today?
Used to have an Up! mini (which I swapped for a DJI Phantom 2) and areas under supports generally turned out quite good and support material being fairy easy to remove once you got it started. Mind you I was working with ABS vs PLA. (this is my first venture into printing with PLA)
So many setting to go through with Slic3r that it takes a bit getting used to whereas the Up! Mini slicer software didn't have many settings. I tend to do a lot of technical pieces that usually require supports so I would like to solve this. Also is there a manual for the Slic3r software? (I can't seem to find one and it better not be in the second book I got with my Printer or I'll feel like a fool) I can only get info by hovering over the settings and watching the hints that always disappear too quickly. (have to hover many times to read full text on some hints)
I can take some photos but I am sure others have run into similar problems before.
Any help would be appreciated.
Thanks

Hi Robert,
I guess I have the same problem like you.
When printing with support for any higher overhangs and it is printing only some small pillars it gets printed fine and also easy to remove.
But when I need to print a bigger area for big overhang it is quite hard to remove and the surface is very stringy.
An extrem example is the portal box I printed.
Sadly I haven't found a solution for this yet.
So if someone has any suggestions for us this would be really great 🙂

You certainly should try the new slic3r beta, but please get the new slic3r settings as well. The supports are much improved.
Re: Surfaces under supports not well defined. (Noob question)
How do you load the new settings int Slic3r?
Everytime I try to load an .ini file Slic3r shuts down.
What file am i supposed to load into Slic3r?
Why are there filament, print and printer directories on github as well as simple.ini and slic3r.ini
I have no clue as to how i load those settings? Loading any .ini file under "File/load config " just shuts down slic3r.
Can someone direct me to a location where i can find out how these ini flies are loaded?
Re: Surfaces under supports not well defined. (Noob question)
What OS?
Simplest way probably is:
- find the folder where Slic3r stores its settings (ie. slic3r.ini etc.)
- just replace everything in there with the contents of the folder from GitHub
- start Slic3r, you should see all the settings available

so installed the new Slic3r beta. Had it up and running. Then windows 10 decided to do about an 4 hour update. Now my original Slic3r and the beta version won't even start up. Help!!!!!!!!!!!!!!!!!!!1
Re: Surfaces under supports not well defined. (Noob question)
Okay I eliminated the .ini files from github from the appdata/roaming/ (print, filament and printer folder now at least Slicr3r fires up. makes no sense that the .ini files would screw up the works
Re: Surfaces under supports not well defined. (Noob question)
I have updated the readme on https://github.com/prusa3d/Slic3r-settings

Janik,
thanks for the update.
It will never be perfect. For surfaces like yours, you may try to increase the number of interface layers from 1 to 2 and to decrease the interface gap somehow. But then the support will be more difficult to remove. This advice is therefore only applicable where the support is easily accessible.
