POST ?

[HEAVY METAL]

The mill i am programming for, the z axis is + into part and - out this is the opposite of what i am used to seeing.Do i need to change my post or is this a tool plane setting within mastercam.

 

 

thanks h.m.

You have choice,

you can change your post, so it will be able to generate Gcode correctly for this mill.

Or you design, in MC, in Z- so the actual post will do job.

What do you mean design in z-

 

 

thanks h.m

Is the post change a simple deal or does it require alot of mod?

 

 

thanks heavy

Hello, "HM"

 

I think what "KSOUFI' is talking about is, make sure the Z 0.0 in the drawing is at the top (tallest) point on the part and all other features are negative from that point.

 

But it sounds like the post has a problem.

 

If what KSOUFI was saying was the problem, the parts Z 0.0 would be below all geometry. As such all moves would be in the positive Z plane, and the post would not be outputing "ANY" negative Z moves.

 

Unless maybe - it has something to do with incramental programing?

 

I would look into the post being the problem.

 

Sorry, I'm no real help, I wish I understood modifing post's more. Maybe some of the other's can help you.

PS: thanks for your help - when I needed a post for my machine. I wish I could help you now!

How about Y? Sometimes when Z flips, so does Y, in order to make a proper right-handed coordinate system. Then you get into arc directions, etc. It's a good idea to get a proper, well thought out post worked out. Mprouter for V8 router had more of these post features because you see more of this coordinate flipping in the wood industry.

Now I am no post writer, But I would think that a simple sign change in the format statements for Z may do the trick.

THIS IS A CINCINNATI CIM-X 3 AXIS WITH A ACRAMATIC SERIES 5 CONTROL Z VALUES CAN NOT HAVE A + SIGN

THANKS FOR THE INPUT ANYWAYS

I'm just curious as well about Dave's question. Is either of the other axis reversed?

[HEAVY METAL]

The x and y axis are not reversed

I'm not sure but maybe there is parameter in the machine to reverse the sign on a single axis. I think Haas may have something that allows this to be done.

I know you can change the work offsets page to display positive instead of negative values for the X & Y axes on a HAAS. There might be a switch for that... now you got me wondering.

Thanks guys I'll look into that

I have seen a router that needed a post like this. Z zero is set at the top of the stock and to move down into the material was a z+ move. What machine is this?
