Omniturn questions on tool offsets...
Some details about the tool and part:
Part OD is 2 inches
Tool is a boring bar used for turning the OD,
that faces the front of the machine. IOW, to turn on the back side of the part the spindle will have to run CW (M4).
Touch the back side OD (2" part) and set X-2 for the 'what was the turned diameter' question.
Then set -1 for the 'What is the correct starting dimension' question.
Here is the program, last line is the position move:
G90 G72 G70 G40 G97 G94 F250
T00
M01
S550 M04
T1
G94 Z.063 X2.036
In auto/single block when the G94 line is executed, the X axis goes x minus beyond X0.
It will go to the back hard stop if I let it.
??
Why does it try to go X minus if there is a X positive move programmed??
I'm doing something wrong....any ideas what??
