Proper rotary axis usage?

[mrcodewiz]

I am trying to do some engraving using my 4th axis but can't quite get it to work right.

The cam program is short - select tool, rotary on (a/y inputting the proper radius of my work piece), go around text, rotary off.


I am using the rotary post processer to generate the mach3 code but when it goes to cut, the text is upside down and reversed. I tried moving the text around to various quadrants to see if that was the reason but no matter where I create the text, using the rotary axis (A/Y) causes it to do this.

A/Y ??

What orientation is your 4th axis ?

I have mine pointing down the bed which then means I use A / X

Try using the Mach3_inc post processor, this will support 4th axis and let us know how that works out.

Sorry, I meant a/x. It runs along the x axis and I want it to rotate instead of moving the Y. Right now when I run the program the letters go left to right but they are upside down.

I was thinking about it last night and I wondered if maybe my rotation direction in ports/pins was opposite of what it should be. I have used the rotary a lot but never anything that would have mattered if the direction was swapped.

Quite possible and easy enough to do a dummy run to check.
