I would like to learn more about how AXIS displays the orientation of the tool when executing motion. The backplot lines/trace is correct for my mill/lathe but the B-Axis tool orientation for anything other than A=0 is off.
Here is my mill configuration Geometry is currently AXZ-B. Note there is no Y axis. I have the X Axis parallel to the headstock (+ is away from the headstock going right), the A Axis rotates around X, the Z-Axis is perpendicular to X and + is away from the centerline of the A Axis. The B Axis is located on the Z-Table with the spindle and allows the spindle to rotate around the "Y" axis. What I am observing is that if I issue G0 X10 Z10 A0 B0 - all good, then G0 B90 and the tool orientation moves from parallel to the Z axis to parallel to the X Axis - again all good. If I then issue G0 A90 the tool path is correct but now the tool orientation shows it no longer parallel to the X Axis. This does not match my machine. I would like to understand how the tool orientation (I am assuming this is a EMCPos struct) is rendered based on the geometry inputs. Any assistance on where to look in the code would be appreciated. I have downloaded the code into a virtual machine for RIP so I can test. Thank you! -Tom
