If the D was called before then it would default to the last one run in the program if you have not called one for that tool which it looks like you have not. So if you by chance have D3 for T2 if you post is not set to force out a D at toolchanges then it would not give you one here and would give you an alram because it is too big or too small which probaly saved your but.

I had a G41D03 in the program I took it out trying different things and forgot to put d03 back before I posted it on the forum. It still will not run with a D03 and .236mm in the mill comp.

I didn't know if you can keep cutter comp on with an X Y and Z move.

I'm going to take the haas book home today see if I can find some more on what the comp limits are. For now I’ll just change the program to match the regrind cutter. wink.gif

Try post it with "Plung after first Move" in the lead in lead out and see how that goes.

Ask Haas if it's a parameter or an option because works well here anywhere my D is.

ok I found the problem I can't find a fix. I changed my linearization tolerance up to .1mm and it still puts in this small move (last line on the code Z moves) exp.

If you change your cutter dia in the machine to Zero, will it run the program??

 

If it does try using the wear option for cutter comp.

I tryed comp at 0 and It runs if I have any amount in wear it give a cutter comp error.

The moves that is errors on are only .001mm moves. Is there a place I can limit the amount a small moves in mastercam?

You could try using the filter option. Small moves and cutter comp don't work well.

 

Putting your file on the FTP site might help solve your problem. There are lots of quality people here that can help.
