On my Interstate 5C collet block set, the square block is 1.723" square, giving a center height of 0.8665" above the mounting surface. Interestingly, the hex block is 1.782" across the flats, giving a center height of 0.891" above the mounting surface.
I can’t wait to see this thing!
@mbellon, MeshCAM only supports indexed 4th axis machining, but not continuous. So the collet block is a reasonable way to index.
Makes perfect sense to do it that way you’re doing then.
Once my Nomad arrives I’m going to work up a BobCAD-CAM 5 Axis Mill Pro post processor for it. This package is capable of 3 axis work, as well as 4 and 5 axis indexed and continuous machining… and it is total overkill… but it will be fun!
By-the-by, Fusion 360 is capable of 4 and 5 axis indexed machining currently. They have plans for 4 and 5 axis continuous but the timing has not be announced.
Another CAM package that is capable of 4 axis indexed machining is DeskProto.
