I spend a few minutes this morning making a nesting subroutine, it's not 100% done but will nest the parts. I still need to add rotation so the parts nest better.
nest-test.ngc
nest.ngc
123.ngc
Enjoy

nest-test.ngc
; quantity, X step over, subroutine file, feed
o<nest> call [2][6][123][25]
M2nest.ngc
o<nest> sub
; #1 number of repeats
; #2 X offset
; #3 sub to call
; #4 feed rate
F[#4]
o100 repeat [#1]
(msg, test)
; Set X0 Y0
G10 L20 P0 X0 Y0
o[#3] call
; move to next position
G91
G10 L2 P0 R0
G0 X[#2]
G90
G10 L20 P0 X0
o100 endrepeat
o<nest> endsub123.ngc
o<123> sub
G1 X0 Y0
X0 Y5
X1 Y5
X1 Y1
X5 Y1
X5 Y0
X0 Y0
o<123> endsubEnjoy

Big thank you, I can already see crosschecking with the documentation that while I used to achieve coordinate system offsets with G92, the particular effect I wanted them for is better gained by using G10 L2/20 in LinuxCNC.
In fact, G10 is more of a direct LCNC replacement for my old G92/93 than the actual G92 to which I looked first. For example, the Philips 432 control included axis rotation in G92 and offered absolute/incremental offsets via G93/92. To get the same effects in LCNC it's necessary to use G10.
Now I need to get a grip on calling programs from programs through o codes. The latter are completely new to me.

Hi Big John:
This is probably a stupid question, but since nest.ngc is a callable subroutine I don't think you need a m2 command at the end plus I believe o<nest> sub should be replaced with o<nest> endsub. If this code is still under development it might be useful to look at my topic titled, "Spiral Subroutine". That code nests subroutines 3 levels deep.

At one time for some reason I thought every subroutine needed M2, dunno where I got that idea. Good catch on the endsub...
