hmm interesting chicken and egg problem the pre-interpretation done by linuxcnc has loads of benefits but it can have problems with undefined things ( where to trip on a touchprobe, where it will be when done- but in infinite loop so it never finished that calculation)
better heads than mine will ponder the solution, but i suggest you look elsewhere meaning: look at safely aborting a limited number of iterations ( parallel a limit swx in your office or to your smartphone via relay ). and if loading THAT is too doggy. be prepared to load a more limited number of iterations more frequently. Because the 'proper' solution will be slower in coming than a hack. a LOT of CNC is learning how to get around the limitations. remember all the benefits and its not too hard to swallow. my 2c TomP tjtr33 On 11/05/2015 08:57 AM, Ralph Stirling wrote: > I use Linuxcnc for machine automation in my manufacturing lab, > and am bothered by the difficulty of creating "infinite loops". > I often want to have a machine sit an indefinite amount of time > until a sensor signals it is time to make the next move.
