Slic3r, my favorite slicing program, has released a new experimental version.
Visit Slic3r.org and grab Slic3r Version 0.9.10b
I am particularly interested in the new "wipe" function. I use "bowden extruders" so it is potentially helpful for me.
This version consumes much less memory than the previous ones, and includes a new wipe feature as well as a spiral vase mode. And many other things, of course. Stay tuned for next updates too!
I have done some experimenting with this new version. I am seeing some really intelligent behavior with this slic3r. Using the wipe feature, combined with using the feature that minimizes the number of times perimeters are crossed seems to be producing good results.
Go check it out :)
