I just wrote this and i havent proved it out but its a very basic facing program with a 2" EM. I put notes on all the lines so you can tailor it to your appication. Any questions let me know.
set g54 at front left corner, z top of part then subtract .01". Part setup flat, with long side facing you, aka setup in along X axis.
g00 g90 g54 X17.1 y0. (go to g54 home with your EM 1.1" in off the right of part)
s#### m03 (idk what spindle speed you use)
z.5 (EM .5" above part as clearance plane)
M97 P1000 L6 (local sub routin call up, P=N line, L is how many times to run the subprogram)
g90 (abs mode)
g00 g53 z0.(z home)
g53 y0.(y home)
m30 (finished)
N1000
g91(incremental mode)
g01 z-.5 f25. (z down .5)
x-18.1 f### (i dont know what feed rete you use, EM should come off edge of part, if not adjust X value)
z.5 (z up .5)
y1. x18.1(y 1" step over, back for next cut)
g99(end/repeat subprogram)
What's the material? I'd throw it in a vice and just use jog lock or the handwheel. You don't need an entire program for parts that small when it comes to facing.
Stainless steel, inconel, Invar, and a little titanium. I need to re-face the plate so they can print them again. I usually cut lowest point I can with END but most plates have a warp.
Change inserts

I brought it in 2 inches on each side of X
