I did a quick search and didn’t see anything recent, but is it possible to pause a job, leave the machine overnight and then restart the next morning?
I’m thinking in the scenario of longer jobs.
Yes, this can be done, but it’s not recommended or desirable.
Stepper motors are weird. They work their hardest when holding position.
Instead, note the line you are at, pause and quit gracefully and shut down, then edit the G-Code file, copy the preamble, go to the line last cut, then scroll up until you find a move down from safety height, delete everything above that line and past the preamble back in.

Thanks Will.
Are there any tutorials out there on that?
If not it might be a good thing for Winston to do a demo file/video on. 
Not really. there’s a maybe more detailed entry on the unofficial Shapeko wiki FAQ, but it’s pretty straight-forward to do w/ a basic understanding of G-Code and a decent text editor.
Todd,
Is your job a single toolpath?
Any way you could break that up into smaller gcode exports to run from your CAM tool if you’d rather not edit the gcode?

I’ve done something like make the work heights to split the job into 2 files, which has helped over jobs that run for like 5 hours. I do this in Fusion by using the start and stop heights in the heights tab area. So first job goes from stock top to stock bottom +15 mm on the first job, and second job starts stockbottom +15.5 mm and goes to stock bottom, or model bottom.
Does that make sense? I can take screenshots later if needed.

Todd,
I’ve also done this successfully. On a recent 4+15 hour job I started hearing the router slow. I hit pause and the router stopped just as it was raising on Z and clearing the material. Well guess what, the brushes where wore out! Made note of the line number that I stopped the job at and edited the G-Code as out lined in the ShapeOko Wiki. I did make sure to go back to the last safe Z above the material and it worked absolutely perfectly.
