Hello... If you read http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?WhyManualWhilePausedIsHard then you know that this topic is already discused but near nothing happend. Well we have script for manual jog while toolchange and that's all. And seems that nothing is planed to address that problem as a lot of programming is needed. Is't seems easy for users but hard for programmers. But can be done! As I know the PAUSE is in motion controller. So when we hit pause the motion controller stops but not the interpreter (until the motion queue is full). Now we have machine paused and we can resume that too. But that can be good only to slow down the work. If we want to clear swarf then actual jog is needed and of course stopping the spindle. So as I see the problem is not simple but can be solved. When hitting PAUSE the motion controller stops. And then if MDI/JOG/TOUCHOF is required it's instruct interpreter that it's stopped in line xxx. and to stop interpreter. The motion controller itself remember the position in current line. Now the motion queue is flushed. The operator is able to do whatewer. Then the OPERATOR is obligated to jog machine in place to safely continue work. (that is near inpossible to do automatic and I didn't see machine to do that) In time the RESUME is hitted the interpreter is instructed to start from line xxx. The motion controller does skip (if needed) start of motion until reach position when he was paused. Then does linear move from tool position(where is leaved with jog) to paused position and resume. That's all. Of course the canned cycles... You can decide if the resume is from paused position or to repeat/skip last cycle. And then you can use M0 to pause and then resume. As I know M0 is 'queue buster' so it's easier too.
I just don't understand why so many workaround is suggested for manual jog... and why the problem isn't solved in best/correct place with coverage of near all needs of users? Is it to hard to program? Nobody needs that? I think that should be done. Just see to forum and this mail list how many times that was discused.
