Okuma post

[dan73]

Hello

I have and older Okuma Cadet 4020 here that hasn't had a new program on it in quite some time, before my time. The 4th axis does not like any value over 360 degrees. I tried changing the "Continuous Axis Type" in the machine def, but with no change. I had to update the post from V9 , but it may even be earlier (I saw 8.1 in there somewhere). Is there something I am missing or overlooking? The old programs look fine, but I have no way to go back to earlier versions to test the post. Or is there any parameters or code at the control to allow >360 degreee values?

Thanks for any help

Dan,

 

You have 2 choices

 

1- Change the machine def to 0-360 shortest path.

 

Settings

Machine def

Open ya file

Double click A axis in machine base

Down the bottom right select shortest direction absolute angle 0-360

 

or

Edit ya post and that will depend on what post you started with

 

2 - Change the machine parameter

It will depend on which flavor of OSP you have

 

Parameters

Rotary axis parameter

A-Axis Multiturn function

Select effective

Dan,

...then be sure that the post will output the M15 and M16 for the index direction (CW or CCW)

^^^^ Yeah good point be sure to check this too ^^^^^

Thanks

I did change the machine def to shortest path and that had no effect. I noticed it only "winds up" when I post out multiple tool paths. If i post out a single toolpath, changing the machine def will fix the problem, but when I add the next path, which I am using axis subsitution, it continues where the previous path left off( if I post out just the axis sub path alone, it also works fine). The post does post out the "M15" and "M16". I will try to edit the post but initially nothing jumped out at me as being off.

I looked at the post and I can't see anything that would change this, but I am no expert. What should I be looking for?

If you're using the MpMaster look for use_rotmcode

I'm currently posting as a Haas 4 axis post on X2, anyone know how I can edit the post for okuma?

[Guest greg williams]

It will be easiest to start with an okuma post

The problem is in your post. You will have to modify the wind/unwind section so the output resets instead of being accumlative.
