I had another Bonehead moment yesterday.
I set up my mill.
Set up all of my tools.
Set home, set tool lengths.
Double checked the program.
READY!!!
Hit cycle start, and the spindle goes UP, and over travels, ALARM!!!
Double check 'H1' and 'G54'... all's well.
Try again, spindle goes up!!!
Try tool #2, spindle goes up!!
What-the-hell???!!!!
........................
So I study my program for 10 minutes, re-check everything...check my set up, check tools, check program
re-check my tool table, and there it was.
I'd entered all of my tool lengths into the DIAMETER column instead of the HEIGHT column!!!
D'OH !!!!!!!!!!!!! :withstupi
Lesson learned.
