No. The whole point of the changes under discussion: they are restricted in scope very carefully so you do *not* have to tell the part of the interpreter which does readahead about it, for the same reasons we discussed: avoid queue stalls, and avoid 'backing up the interpreter' (see http://wiki.linuxcnc.org/cgi-bin/wiki.pl?WhyManualWhilePausedIsHard) The only change wrt to the interpreter is the access modality for tool length offset and tooldiameter parameters (#54xx): so far those were considered untainted because no entity except the interpreter could change them. They now can change at any motion (due to toolchange during pause), which is why came up this state reference model in the first place - they are now 'tainted by motion'. That said, the only execution difference will be: if you refer to a #54xx parameter, a sync will happen before the referencing block is executed. So far it didnt. But that shouldnt cause any user-visible behavioural change except that 'current tool parameters as seen by the interpreter are "more correct"' ;). - Michael > Other than that - the chance to move around > during pause is already there. > > Viesturs > > ------------------------------------------------------------------------------ > Live Security Virtual Conference > Exclusive live event will cover all the ways today's security and > threat landscape has changed and how IT managers can respond.
