I think, that following solution might be easy to implement: 1) press "pause" 2) press button, which stores coordinates of current position 3) jog away, do what ever... 4) press button, which returns to saved coordinates. here is important, that first move is in XY plane, Z move is last 5) hit "resume" 6) machine should remember all the variables, feed rates etc. during this pause (i do not know, if EMC already does it. if so, please ignore)
So actually 2 buttons with IMHO simple functions have to be implemented About the safety of such solution: i agree that it is operator's responsibility to make sure, that machine is jogged to place, from which it can safely return to the saved point. I believe (but am not sure) that this way machine can be paused and resumed in the middle of the line... 2010/5/17 Ries van Twisk <e...@rvt.dds.nl>: > > > ------------------------------------------------------------------------------------------------- > tags: Freelance TYPO3 Glassfish JasperReports JasperETL Flex Blaze-DS > WebORB PostgreSQL DB-Architect > email: r...@vantwisk.nl web: http://www.rvantwisk.nl/ > skype: callto://r.vantwisk > Phone: +1 (803) 426-3350 > > > > > > > > On May 17, 2010, at 10:36 AM, Slavko Kocjancic wrote: > >> Hello... >> Not bad idea to be separate item as jog under toolchange can be >> resolved >> quicker. >> I changed wiki and I think all command M0 M1 and M6 can behave >> similar. >> For example if someone mill plastic then can issue few M1 in program >> and >> has optional stop on M1 dissabled. > > Thanks.. > >> If swarf come up then just enable M1 pause and have nice workaround. >> Maybe there is not bad idea to have another one pause button that >> pause >> program like inserting M1 after just current line?!?
