Thread mill on haas 4 axis

[JrScott]

Has anyone tried to use cutter comp to thread mill holes on a haas 4 axis that uses G254 for 3+1 positioning?  My post isn’t turning cutter comp on and I was wondering if it is even possible?

thanks

When you gave it a try what happened? If the machine can support it then go for it, if not then will need to go back to the post builder and ask them to put an error warning when trying to do this. In 3+1 positioning I think it should be supported since on just about every other machine when doing 3+1 or 3+2 positioning DWO type of work we see this supported with no issues.

Never had a problem.

Are you using wear or control comp?

Do you have a lead in line?

The post would not post out a G41 at all. We are using wear comp. I sent the post back to the post builder to hopefully get it resolved.

That is what you should have started the conversation with. Take the generic HAAS post and post code with it for a 3+2 position using WCS to force it to think it is in TOP/TOP/TOP for one of the places you are trying to make this work. Pastes that section of code into your program using the G254 or just manually add the G254 to that and see if ti runs, If it does then more proof back to the post builder to fix it.

Missed it thank you for pointing out my mistake.

Sorry JrScott I missed that the first time around reading it.

My post also fails to output a G41 if my initial move is an arc rather than a line.

Most controls have issues with cc starting on an arc.

No worries crazy^millman.  I sent the post back and am waiting on their response. My lead in lead out is not an arc.
