I uninstalled and reinstalled V4.0 on Monday night, and did Help/reset all settings. Same symptoms before and after. I am going to deauthorize this PC and try an install on a laptop that has never had S3D. I am kind of invested in using my main desktop for slicing as part of the whole Fusion/netfabb/S3d/octoprint workflow, so hopefully something can be figured out. The PC is not having any other issues with anything else. I may install cura and see if that has any issues.
Win7 32 bit
S3D 3.1.0
zero length gcode file output with previously printed stl input and new stl files, nothing works all of a sudden.
I have the same problem and I load only 1 STL file at a time for printing. 3.11.0 has been working fine for years but suddenly both new and old STL input creates zero length gcode files. I downloaded version 4, same problem, zero length gcode file output.
Everything in S3D looks normal and the playback is normal, the only problem is zero length files.
Earlier I posted that I had the exact same problem then I got a brain storm and saved to a different USB thumb drive and the results were OK, apparently the original thumb drive had a bad spot even though I ran check disk on it. The weird part is that all other files including the STL saved fine.
