Xubuntu 14.04 LTS 32 Bit
After installation s3D worked fine. Then i would print 3 models at once via USB after 15-20mm skirt printing stopped and system was black (no reaction) and then shut-down. After restart i could not longer print via USB from S3D (Error massage that a connection not possible). Saving the G-Code is possible via Manual Control of S3D. After some reboots i have the same behaviour.
Any hints what to do?
