Mach3 Continues 4th axis Post processor

[Bernic]

I have two 3/4 axis vertical mills of which both run a 4th axis rotary table. This rotary axis turns about the X-axis so called A-axis. I've downloade a post processor from Autodesk forums which I'll attache to this post. I'll also attached the part I'm looking at milling when I figure a way to get this to work. The tool path seems to generate with no issues and same with the code. However, when I generate the code to run in Mach3 the piece just keep on turning in the rotary axis and do not actually cut out the pockets as designed. I'm looke at the processor and with my limited knowledge can't seem to fin an issue(that's maybe due to my limited knowledge). What I do notice is that there is no Y-axis movement during the process on Mach3(Y= 0)?

The part's code is 1001.tap

How have you set the Rotational mode in Mach3 ? See image and set as shown if not already set as this.

As for Y axis moves, there will be none, the axis is moving in the "A" axis so you have lots of "A" axis, "X" axis and "Z" axis moves only during the program, there will be "Y" axis moves at the start when moving to start of cutting position and at the end of the program to move the machine to a safe/home position.

Hope that is of some help to you 🙂 🙂

Where are you setting the work zero in mach3, other than what @engineguy said it is all I can think of that may course the problem you are having.

Thanks Daniel for your comment I did get it to work with the setting in Mach3 as @engineguy suggested.

Thanks again

Hello Rob

That worked and thank you for that.
