This is an updated version of millmutiple.

With this version you can select:

The part file to run.
Rotation of part.
Where to start the first part.
The distance between parts.
The direction of the parts.
How many parts.
The coordinate system to use.
The tool to use for tool radius compensation.
The feed rate.

Requires check_cord3.ngc and M110.

The concept of this untested sub is to take a part or pattern file and duplicate it as many times as necessary in what ever direction you wish using the ngcgui.
This was set up for XYZ machine such as a mill/router/plasma.

With this sub you should be able to take your existing part file and duplicate it.
; millmultiple3
; run multiple copies of an existing ngc file for xyz machine such as mill/router/plasma
; set start location, and offset locations in x and y direction
; existing ngc file must be a sub and have a numerical name such as 503.ngc in example
; part can be rotated

To try just make your part file a sub by..

Name the part file with a numerical name (say 503.ngc)
Make the file a sub by

Start and end the file with...

o<filename> sub
(not_a_subfile)

#<Tool_no> = #1
#<Feed_rate> = #2
#<Z_feed_rate> = #3

;;;lines of code;;;


o<filename> endsub

Be sure to have all files in the correct directory.

For example the file 503.ngc is
o<503> sub

(not_a_subfile)

; sample file for millmultiple3 not for actual machining

#<Tool_no>	 =     #1
#<Feed_rate> =    #2
#<Z_feed_rate> =  #3

G0 z.025
F#<Feed_rate>
G0 x0 y0 z.010
G41 D#<Tool_no>
G0 x-.75
F#<Z_feed_rate>
G1 z0 
F#<Feed_rate>
G3 x-.75 y0 z-.125 i.75
G3 x-.75 y0 z-.125 i.75
G0 z.025
G0 x-2 y1.5
F#<Z_feed_rate>
G1 z0 
F#<Feed_rate>
G1 x2 z-.125
G1 y-1.5
G1 x-2
G1 y1.5
G1 x2
G0 z.025


o<503> endsub




Because ngcgui allows you to string several subs together before you finalize you should be able to set up several rows and columns of the part.
Again this is untested and you will probably only want to use this as a starting point to fit your needs.




I also have a slightly different version which creates rows and columns of parts which I will post latter.
