Having taken the plunge into 3D printing, it has become a very fun learning experience.
Over the past 2-3 weeks I have been working to refine my printer, and find what works, and what does not.
The First thing I learned, is that not all STL's are the same. Depending on what was used to generate the STL, it may or may NOT be printable.
The other thing I learned is a problem with Slic3r itself. It is a memory hungry program, and running it in a 32 bit sys with only 4 gigs of ram does not make it happy at all.
I have been running it on my Win 7 32 bit sys, but have being plagued with Slic3r crashes on large prints.
So I went to the Slic3r web site, and found that there was not only a 64 bit version, but there was a new update, 0.9.7. I have been running .0.9.3.
What a HUGE difference.
I have 8 gigs of ram in my main 64bit sys. And Slic3r will use every bit of it when starting to slice a large print.
Infills were changed, and they seem to be doing a way better job now.
I recommend that you get the update if you have not already done so.
On another note, has anyone ever got ReplicatorG to work with the Sang/Merlin combo...?
I found a machine/driver file that claimed it would work, but so far have been unable to get Rep to connect to my printer....
