4th Axis Limit of Rotation for Haas

[RObert TImby]

Hello All,

 

It seems that I'm having a problem with my gen haas 4th axis post from 2017. I'm trying to limit the the 4th axis from winding to high and alarming the machine out. I looked up 4th axis limit here on the forum and tried them to no great out come. I went in the machine def and changed the number of degrees under travel limits and that it not work at all.

 

 

I down loaded the MPmaster and tried that also, the change:

one_rev     : 1     #Limit rotary indexing between 0 and 360? (0 = No, 1 = Yes)

That did nothing also

 

Any ideas of where I'm going wrong?

 

Thanks

None of the 4 Axis post processors make use of the Rotary Limits. You will need to purchase a post processor with this capability, or add the code for the limits yourself. This is a pretty involved task, so I'd leave it to the professionals, unless you are fairly knowledgeable in Post editing.

 

It's a case of "the tools are available to you, in the Mastercam Interface", but you have to "hook it up" to get the functionality to work.

 

When I've set up a 4X post like this in the past, I typically use a 5X post as a starting point, and suppress the secondary rotary.
