M47 L# function

[Robertspark]

Is this not the same as M98 Pxxx Lxxx?

..... From the Mach manual

10.8.5 Re-run from first line - M47
On encountering an M47 the part program will continue running from its first line. It is an
error if:
♦ M47 is executed in a subroutine
The run can be stopped by the Pause or Stop buttons
See also the use of M99 outside a subroutine to achieve the same effect.

i use m47 all the time on the router- for making repeat parts .
i use an m01 at the start
run job code
a move away from fixture move- so it can be reloaded
and m47 for repeat
this way it moves the head away from me and leaves the spindle running ready for next job- just press feedhold off and its away.
press stop when all parts are done.
saves a lot of time and doesnt stress spindle or electronics with constant start/stop
