Indefinitely…JUST DONT TURN THE POWER OFF to your controller or computer.
longest pause for me was about 18 hours just dont lose power
Cancel the job let it go home rezero bit change settings and rerun
That would be the down side but if it takes hours off then time is still saved.
depends on bit size
Ran to the shop and made a long boring vid lol. I did 4 cuts with the bit you are using in some scrap pine. All cut parameters were set the same with the exception of the inch per minute being 30, 60, 90, and 120 ipm so it might give you a little heads up on what you want to do hope this helps.
That looks great!
How much sanding was required?
