dear...

i have set my G54 to x 100 y 100 and z to -10

then i did homing to all axis.

now machine coordinate DRO is x0 y0 z0

then i select the G54 and click go to zero

the machine coordinate moves to x100 y100 and z50 why z 50 i dont know why?

when i switch to offset coordinate it shows in the DRO x0 y0 and z40......why z40??

plz any help to solve this problem..

best regards...and thanks in advance.
