I am programming a G&L VTC1250 with a Siemens 840d control.
I wand to probe an existing hole at a known Cartesian coordinate and compensate the work shift for both Cartesian and polar coordinates.
The print dimensions different sets of hole patterns with either Cartesian or with Polar coordinates and I want to pull the dimensions directly off of the print.
The existing hole was put in from the opposite side so I need to align the second side with the first.
For Cartesian, I use G508 and for polar, I use G507 work shift.
I want to do what you used to be able to do with G92.
It looks like CYCLE 977 is what I want to use but I cannot understand the programming manual for what the inputs need to be.
On our older VTC60, I used to use "PRDC" cycle with the last value being the angular position to "G92" the c axis at.
Any help and examples of how I should proceed would be very appreciated.
