Once a job has been completed all the tools may have been removed from either the turret on your Haas lathe, or carousel on your Haas mill, however the offsets remain in the tool and work offset pages. This is a dangerous situation to be in as another job could be set up on the machine with the wrong offsets.
On a Haas machine there is an easy way to clear the offset pages:
Put the machine in HAND JOG mode. You can now toggle between the tool offset and work offset page using the OFFSET key.
Once you have navigated to the screen you want to clear, press the ORIGIN key, this will then ask you whether you want to zero Y/N?
N.B. On later machines (series 9 lathe software or series 16 mill software) when the ORIGIN key is pressed you will be given the option to clear a cell, column, row or all the tool offsets.
Cursor to the option you want then press the WRITE/ENTER key, this will then ask you whether you want to zero Y/N?
Press the Y key to zero all offsets.
Press the N key to abort.
