Haas ST Lathe - Parts Catcher

[rw_skinner]

I'm wondering if the parts catcher can be set to go into position just before the cut off where the parting is near done, rather than at the beginning?  Reason, tired of parts catcher and door filling up with chips and coolant spraying our the door.

So, if you're parting, you have the option to reduce feed rate at a certain radius, typically very near completion of the parting operation.  Would a person be asking for trouble to move the M36 to the section where the reduced feed occurs?  You don't want the tool dragging while your waiting on the catcher, but that seems like a better time than catching all the parting chips right?

Hi @rw_skinner,

There is no reason why the post couldn't be modified to move the part catcher call to where you want, i am curious though, have you hand modified the code to place it where you want and ran it on the machine to check it all works?

Wow, I replied then it disappeared.

No, I haven't tried it yet.  I was more less asking for opinions in case I was overlooking something like dwelling too long in a groove.  

[rw_skinner]

I think a M35 at the beginning will get the 2 stage catcher in position, then a M36 could pivot it up in place just before the final parting.  This would keep it from dwelling very long in one spot.  I need to try that.

So this works great....

It was hand edited at this point, but I believe I'll see if I can edit the post to make those entries if reduced feed is checked.
