I had a gentle crash today (bent a reamer), and if you are going to have one I like the gentle ones. The problem was H00 as the tool length offset in my post. There is a setting on my Haas that checks to be sure the tool number and the offset numbers agree and I know it used to work because it has stopped simulations a few times for me with a warning.
Today it did not work and I can't figure out why. I ran the program below in simulation several times and the warning never came on. I have not changed anything in the post my CAM software outputs but obviously something has happened.
I thought one safety measure would be to put a large value in the length offset column for H00 but there is no 00 in the Haas length offset table. Viewing this fact I wonder where the Haas was going?
The real problem is, what is in my post, or what setting has changes that would disable the warning from coming on in a situation where it obviously should?

I'm a bit of a slave to my CAM program so when things like this come up I'm in trouble. I thing the problem is with the Haas and I thought this was the place to find out.
