Hi Max:
Probably just the raw DXF's for the K40. After generating a gear onto the project screen,
just hit the DXF button for output, and select the gear you need in the project tree. Hit
output and youll be asked for a project name if you dont have one set.. the file will appear
in C:\Gearotic Thoughts\GearData\YourProjectName\*.dxf
I usually print at 98% scale.. allows some backlash in case you neglected to add some in.
If you get lost, do a web search, this forum has almost every question possible asked somewhere..
and if all else fails, or your too lazy to search.. ask.
