Hi Everyone,

I want to program my machine with less number inputs and creating what is known as a "DuoLoop" configuration.

Right now I have

g0 g21 g90 g50 g80 f100
g0 z0 g0 x0 y0
m98 p1 l10
g0 x0
m30
%
o1

g91 g1 z-.5 f50
g90
g1 x-50 f200
g1 y-2
g1 x0
g1 y-4
g1 x-50
g1 y-6
g1 x0
......ETC until .
g1 y-16
g1 x50


g91 g1 z-.5 f50  (gcode for z movement repeat)

Then I have a gCode for a reverse direction..
g90
g1 x28 f200
g1 y-16
g1 x0
and etC...

I was wondering instead of writing out all these numbers is there a way to put in a Gcode where I only have to use

x-50
y-2
x0
y-4

and repeating this step continuously? I'm constantly changing my values and it gets restless going back and changing every number.

PLEASE HELP! Not sure what Gcode I use for this
