I’m learning on my Fanuc 21 mill. Trying to do a simple go to the work piece with g54 then from that position move on the x axis 4.0 inches. When I input it in Mdi and tried it several ways it keep traveling at an angle right from the start, doesn’t rapid to g54 then travel the 4 inches along the Z
Could it be parameter 1401.1 is set wrong?
Thanks

This should help explain it
Maybe this would work
G54
G0 Xn.nnn Yn.nnn
G1 Zn.nnn Fn.n
Still moves at an angle from the home position

Normally making a G0 move, each axis moves independently and simultaneously, taking the shortest path to the assigned position which may be at an angle depending on the starting and ending position.
If you want the X and Y to rapid along a specific path, then you would really need to make a G1 move at a high feed rate.
It does work, goes to g54 then the x axis but it’s all rapid thru the z too

You can NOT have a rapid (G00) and a feed (G01) in the same block. Fanuc only looks at one or the other as you can not do both.Quote:

Right now I want to leave Z out of any movement until I get it figured out.
I’m just trying to mill a key way in a bar

I think what you want is this
G54
G0 X0.0 Y0.0
G1 Z0.0 F5.0
G1 X-4.0
Bingo! You win a case of beer! Worked perfect
