Drilling lots of holes thru 35mm bar.
Picked up a Cogsdill Burraway to chamf top and bottom from one side, works well.


To get it up and running I simply stripped out the drill code and inserted a sub call between each of the coordinates. Only issue is there are 96 holes:


%
(Drilling)
........
G00X18.Y132.5Z30.
M97 P10
Y107.5
........
repeat 96 times!
........
Y132.5
M97 P10


G00Z250.
X-80.Y250.
M30


N10
G00 Z0.
G01 Z-15. F600.
Z-24. F150.
G00 Z-63.
G01 Z-56.
G00 Z30.
M99
%


I've got lots of similar parts to do, different number/position of holes.
Is there a drill cycle which will do this?
Is there a more efficient way - without macros - to set up the code which avoids the repetition of the sub call?


Cheers

Haas supports G91 + G70/G71 to repeat a subroutine multiple times with a fixed incremental shift.
This can be very useful for patterns like grid or linear hole arrays.
However, this only works if the holes follow a repeatable incremental pattern,
which might not suit your case if the holes are scattered.
