M00 jog and Resume

I think it depends on what you are trying to do exactly. For example, I modded my S31100 to add an encoder and rigid tapping. I like to use tapping gel as I dont like breaking taps . So I do a NC Passthru in Fusion that does the following code (note that I disable the coolant for tapping tools so I dont use an M9 here to turn it off, otherwise you would want to do that):

This works fine for what I want to do. However, with M0, LinuxCNC remains in AUTO mode. So MDI and Jogging is not allowed.

If you want to jog around while the program is "paused", that is not possible with pathpilot, although with eoffsets, it is possible with LinuxCNC as a whole.

Hopefully that answers your question?

No, that's not what I'm saying. Maybe I don't understand what you're looking to do. But I just outlined one way to stop the program, move the spindle out of the way, which would allow you to measure something while it's in the vice.

If X and Y are not positioned where you need them to be, you could use machine coordinates to position X and Y as well before the M0.

Further, you CAN STOP the program, jog around, and then use their run from line feature to pick back up where you stopped it. It would be easiest for you to still use a planned M0 or M1 in these cases though so you could easily find the the line you want to resume on.

Making it easy on yourself requires a bit of pre-planning, but there are definitely options.

Something like this:

Old video.

Vmax (which is ironic because the first snowmobile I owned was a Vmax 540cc (hence the 540 in my name) - though I realize you are likely referring to the motorcycle version),

If you look at my first post, I suggested a way to stop the spindle, and move the column to the tool change position (or wherever G30 is programmed to be), and then M0 (pause) the program. In that manner, the spindle is not running anymore. If you are programming in an M0 anyways, it's just as easy to program the other stuff prior to the M0 too.

^would get you there.

Not sure what CAM you use, but you can do this in Fusion360 very easily with a Manual NC pass thru, but it does (or did) require a small post processor mod. I'd be happy to help should you use Fusion and want to make the change.

Switching the spindle off and on is not really all that difficult to do when the interpreter is paused. All you need to do is to cut the spindle enable signal in hal or in hardware.
Jogging would need to be done with external offsets as tommy has suggested. If you use a custom panel button for pause/resume you might even find some hal magic to make sure that the spindle is at speed and the external offsets are back to zero before allowing the program to be resumed.
But of course one would not be wrong to call these solutions workarounds for the fact that regular jogging is indeed not allowed while the interpreter is paused.
