Hi all. I finally got Slic3r to build on my ubuntu machine 12.04 LTS and i managed to get one sucessfull calibration cube to print. When i tried to print another at a different layer height my printer flipped out made tons of noise drove the extruder faster than i have ever seen it go before and continue until the filiment broke at the bolt. I have tried everything to correct this including resetting the software and re-downloading the current version with no avail. I am using the latest version 0.92 of slic3r with the latest build of pronterface from Github. Thanks
