And I just found that it generates NO errors for either a gcode export that generates no file, and issues a blank page when you print it. The only file type it will generate is *.FCstd's. To quote Jackie G., What a revoltin development that is... Freecad-irc won't let me talk unless registered but I can login thru github. But when I put my email addy into the github screen it reply's that the address is already in use so I'm locked out. So I quit konversation. No real traffic there anyway.
