no too sure on this matter, as realy a M00 in the code on a tool change, when machine stops, press abort, come down measure tool or call sub what ever.. then do a run from tool pickup or just after, you already have all start codes ready to go and points to start from.. i dont see how a Mcode would help here.. unless i am missing something? here is what we can do a on a fanuc machine, only becasue we have a relative offset that we can zero any where and not effect any offsets etc.. say we are drilling holes in stringy material.. when we retract we wish to stop it and clear..then go from where we was we press feedhold, machine pasues. we zero the relative on Z=0 this gives us a ref to come back to. change to manual mode, stop spindle jog clear of the hole, clear chips start spindle (can be any speed as fanuc will have current speed and feeds still set in mem) jog back to where we set relative zero point. change back to auto unpause, away we go the down full is u need always set relatives to zero or have other measn of coming back to the same place or bad things will happen. emc u cant do this so easy or at all, beacsue u can not change into MDI or Manual from Auto mode paused only if u abourt fully. infact rereading your code layout it would solve the switch from auto to manual/mdi mode i think.. so just need away to note positions properly. id love it if EMC had easy to use relative offset for manual work u can zero and use as like, and not change ur G54s etc.. rob ------------------------------------------------------------------------------ RSA(R) Conference 2012 Save $700 by Nov 18 Register now http://p.sf.net/sfu/rsa-sfdev2dev1 _______________________________________________ Emc-developers mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-developers
