Toolpath view incorrect
« on: September 25, 2009, 03:34:09 AM »
I think I am right to say this one is a bug.    We will see when someone shows me my error.    ;D

Very simple gcode as follows,

G1 X0 Y0 Z50 A0
A360
Z40
A0
Z30
A360
M30
%

When the "axis of rotation" is selected as X, in toolpath configuration, the toolpath displays correctly. See pic X-rotation

However when Y is selected, then the toolpath view is not displayed  correctly.  See pic Y-rotation

They should both show three simple rotations of the axis.  As the "X-rotation" pic does.

Any ideas of what silly thing I may be missing.  ;D

Just curious.  Are you cutting a cylinder?  Calling the "A" axis indicates a 360 turn around one.  No idea why the different rotations would give different pics.   When I post your code to my 4th axis configuration I get a "slice," view of a cylinder being cut to three different depths.  There is no "x" or "y" movement so the cuts are all at "X" 0 and "Y" 0.

Yes this toolpath shown is just as simple as can be to demonstrate the problem.

Where I see it is a toolpath to take a rough piece of stock down to a cylinder.

I am not getting much response, so I suppose there are not many doing this sort of rotary axis stuff.

I see the exact same thing. Probably should tell Brian on the Yahoo group.
