Release notes V3.16

The new GrblGru Version is ready for downloading at https://goo.gl/quFpdZ
The main focus is set again on the 4th axis. From now this axis is part of the 3D model and can be designed by the user.
As example for this type of machines we have 2 new models in GrblGru.
The first one is used only for demonstration. It's a ShapeOko3 with a 4th axis, placed in a square cut-out of the wasteboard, which allows machining of bigger workpieces.
The second model I've got from a GrblGru-friend, who has designed a pretty cool engraving machine only with X, Z and A axis. It can be used for engraving a cylinder.

Have fun GrblGru
