Can anyone telm me how to change the "machine position" to display inch. I found out how to change the position screen to inch but the machine position still shows mm. Can anyone tell me how to change this?

System parameter 3104 bit 0 I think. Be very cautious of altering system parameters and always backup your system parameters before making any changes.

Command G20 in MDI
G20 = inch
G21 = mm

Hello from the future! What worked for me on my Fanuc Series O-T (in my case) was parameter N0001 used to be 01100000 , now it is 01100001.

xxxxxxx0 = MM
xxxxxxx1 = Inch

Hope this helps someone else some day. Chip had the right idea.

alright i cant edit my post anymore...? anyway, this wasnt the solution. jog rate got messed up, its like it was reading in inches but was pulsing in MM. gonna try some other stuff i guess and send an update

OK I finally got it figured out! This worked on my Fanuc OT.

Change parameter N0063 , bit 0 from zero to '1', or 00000000 to 00000001

In other words:

---No.------DATA--------
0061 00000000
0062 00000000
0063 00000001 <--- this guy controls this inches/mm setting for machine coordinates. 0 = mm, 1 = inches

happy parameter hunting!
