Problem with generated rotary job toolpath.
« on: March 04, 2019, 11:07:42 PM »
I refer to my topic in Vectric forum and need help in order to find out why my generated g-codes gives a different machining toolpath than it was shown in the v-carve softvare.

Are there anybody here who can help me with this issue?

I have done some rotary stuff several years ago.
I can not help you much, but if it was me I would
start with a very simple like turning square to round
by some length.
Then go to something a little more complex like cutting
your name in the turned piece.
That way you can maybe identify what the problem is.
I think I had to modify Vetric's post processor when
I done mine.
Maybe Ger with chime in and give you some help.
He seems to be quite knowledgeable on this.

Are you sure the a axis is rotating in the right direction and at the correct distance.

To check the rotation place a hex head bolt or a piece of hex bar end in the chuck and set a flat square with a clock or a square block.

Then enter and run this program :-

G92 A0
G00 A60.

The A axis should roll the top of the chuck toward you for 60 degrees and the next flat should be square to your original flat.
