Hi, Paul
I'm not an expert with offsets or tool tables, so lets go through this slowly, Work offsets are G54 through G59 I think you can have more
though, lets deal with them later.
G54 generally is reserved for your home position, so don,t mess with G54.
Home your machine, goto the "Offsets Page", Verify that Current Work Offset is 1, Which is G54, 0,0,0 both displays.
Now Click on Fixture 2 G55 Button, to the left under Current Work Offset, enter in X, Y, Z, a value of X, Y, --1 and Z, +4 (making an asumtion that your Z
axis is 5 in away from the table when Homed) , note the Right Coord's Window reads a X, Y, +1 and Z, -4 value for there axies,
How click on Fixture 1 G54 Button, Then you'll see 0,0,0 left and 0,0,0 right Display, G54 is Home position..
Click on Machine Coord's Button, It shows 0,0,0, So the G55 is like jogging to a spot and Zeroing the Axies, more or less.
So now goto "Diagnostic Window", Theres a window just to the right of the Reset Button click on it, it'ill ( New Word Sorry) turn Yellow,
type in G54 Enter Current Pos. should be 0,0,0 and Work Offset should be 0,0,0, Now tipe in G55 Enter, should see -1,--1,+1 and +1,+1,-1
So now you have a +1 offsett XYZ, new tooling plate corner for a 1 inch plate, the actual distance for Z axis to get to the top of tooling fixture will be a
larger number depending how high it home SW is.
G54 and G55 in your G-code will move cutter to there set Positions.
The MDI Window will allow inputs also to see the ABS distance from Home is "Machine Button" Off , to see Pos from current tool table 0,0,0
turn it ON.
So the G55 is like jogging to a spot and Zeroing the Axies, more or less.
Think this is Correct, Hope it makes sense.
On exit of mach save the Offsets window will open up, save them.
Digest this I'll Post tool Info later,Chip
(edited Z values) Had them backwards, surprised some yon didn't jump in on this mess-up. No Adult supervision, H-U !!
(edit 2 ) to make beter sense. More work needed. back in a while
