re:G92 and M99 code uses?

Tauseef,

Have you tried:

G21 (metric units)
G91 (incremental moves)
G81 x1 R.50 z-5 L49

This one 'G81' line "should" do what you want!

By putting the control in incremental mode, the x1 part of the G81
will move 1 unit in x before each drill cycle, and the loop L49
should repeat this process 49 MORE times (after the original
line/block is executed). You may need to loop 50 times, depends on
how the internals of the software are/were written.

Hope this helps.

P.S. Brian, I don't think CncPRO supports conditionals... Yet?
