Hi, I would like to turn on the OP STOP with a PEEK or a POKE (I didn't remember I remembered those) or a G10 or a.... from within theprogram. With the down turn in the economy we are at 40 hours starting this past Monday. First time in 19 years it was under 46 madatory in the machine shop. Now the planners can't have the machines running overnight lest we literally run ourselves out of work. So I would like to use the part-cycle times to stop the CNC one and a fraction parts before 3:30. So the machines are idle before we leave (ewww). And I think it would be fun to press the OP STOP from inside the CNC. Just the one M1 in the programs right before the transfer. Ah twin turret dual controls "where is thy M1". Hmmmm. As I type this I see I can leave the op stop on all day and put a Do/ While statement in with an M1 to run after [3:30pm - cycletime] but that isn't nearly the fun of screwing around with something that will probably never work. And that OP STOP light being on all day depleting our natural race horses would bother me.
