Comments
G10L2P1O1X-15.Z-10.;
defines work coordinate system zero
point to be at X-15, Z-10 from the
machine coordinate system zero point
G90;
G10L2P0O1X-15.Z-20.;
sets external offset of X-15, Z-20 moving
work coordinate system zero point to be
at X-30, Z-30 from the machine
coordinate system zero point
G90;
G10L2P0O1X-30.Z-30.;
sets external offset of X-30, Z-30 moving
work coordinate system zero point to be
at X-30, Z-30 from the machine
coordinate system zero point
Important: This modification is permanent. The new table values for the
work coordinate systems are saved even when control power is turned off.
