I've got a bit of a cycle time problem and a question I hope someone can help me with. I've got Haas VF-2 with a 25 tool carousel. Here's my problem, I'm running a job that requires 4 program stops (M00) where I bring the spindle down with a pin in a tool holder to load the pc up to. My next tool is an end mill that is 10 tools deep in the carousel, so the pin rapids back to Z0 while the carousel indexes slowly to find my end mill. Is there a way to get the end mill to get into the next tool position before my M00? I'll post a portion of the program so you can see what I'm doing. Thanks

I think you can put the next tool number ahead of the M00 and the changer will pre-position that tool. That is just the tool number Tn without the M06 command. My machines see the next tool in look ahead and pre-position well before the change is called. I have not used M00 and I just wonder if that blocks the look ahead. It would be logical if it does.

Thanks for the reply Geof, I'll give that a try in the morning. Yeah, the M00 does stop the look ahead that's why I was wondering if there was another way to get the next tool ready before the stop. It's adding about 40 extra seconds to my cycle time. Thanks again for the tip and I'll let you know if it works.

Is this a dual-arm changer or an umbrella style? If it's a dual arm, you should be able to put the next tool call right after the tool change, i.e.:

G110 X.3125 Y-.17
G43 Z1. H01 T02 (PRESELECT NEXT TOOL)
G00 Z-.2

Yes it's the dual-arm changer. I didn't realize I could call up the next tool like that. Geof also recommended I try that method, I knew it was going to be something stupid easy! Thanks guys, much appreciated.
