We are trying to run G54 on the Kuraki instead of G92 and it either over travels in z or does not return to home. have tried different formats for the return line and nothing seems to work. Any help would be great.

Here is a section of the tool. I have tried several ways g49 h00 not sure what it needs to send the Z home.

Try adding a tool length cancel before you send it home,, G00G49Z5.0 for example,,just make sure that your tool length isn`t more than than the Z5.0 clearance move,,
 
Try this.

G0G90G54X-1.7 Y-.9375S3500 M3 (You need X and Y for G54 to register)
G43 Z1. H01 M8
G1Z.2F50.

G1 Z0g0 Z.2 (You have only Z + values! And no X,Y movements)
Z.5
Are you facing straight down to Z0 and then up again?

G80 G40 G49 M9
G28 G91 Z0 M5

If you are using work coordinate systems try this at the end of the tool.

M00

I think if you cancel your offset before zero return it will move in a Z- direction.
