I stopped the program, threw away the part, corrected the tool diameter and started again at the top of the program. To my surprise it did the same thing again. Just to be sure I checked the tool register to be sure the correct diameter was listed for the tool in the spindle and ran the program from the top leaving the ruined part in place. It still did not recognize the new diameter. I then called another program to active status, then called the first program to active status and ran it again. All was well.
I apologize if my terminology is not correct, I'm rather new to CNC. I looked through the manual and found lots of information on tool offsets and such but never could locate anything that described the situation I was in. There are a few guys on this site that know the Haas manuals like the back of their hands so I doubt if an explanation is far away. 
Thanks for reading, Vern |
Vern if you could post your code where this happen it maybe helpful as some program their tool prep and paths a little different then others.
When you stopped the cycle of from running did you hit reset.
When starting the tool cutting again did you start it from the very begining or at least calling up the tool change portion of your code.
When reading M6T1 this will also set your H and D active at this point. Some machine you can go right into a G41 with out calling up your D value as it is already active.
