Rotary axis display in toolpath window. Can it show B?
« on: October 15, 2009, 06:00:16 PM »
For as long as I have been doing 4th or rotary axis work on my router I have believed that Mach can
only represent A axis correctly in the toolpath window.  Not B.

It occurred to me that before I start advising others that this is the case, I had better check that I am not mistaken and just doing something stupid.

So my question to the experienced 4th axis users.  Can the toolpath window represent B axis toolpaths correctly or not?

For anybody who may have been interested Brian has confirmed what I thought,

that only A axis can be displayed correctly in toolpath window. Not B or C.

Hello,
This is an old post and I am a new user.

Is this still an issue with the Tool Path Display.

I have been having problems interpreting the Tool Path Display.
So I loaded this stupid simple hand written g-code to test movement directions and orientation.

The g-code results for XYZ movement result in a path that is what I expected, and is what I see the machine perform.
The g-code results of A and C rotations result in a path that is unexpected, yet the machine performs as expected.

If the Mach3 Tool Path Display is not adequate to display 5 axis movement, what viewer do you use?
