Any of you dare to leave your machine running completely unattended (overnight)?
I run several small panels (nested) that take hours and have run several of them without a hitch. I feel like Im insane but Ive been tempted to set them up at the end of the day and let them run overnight. The smart side of me says find a $9/hr hunky to sit there all night. Ive never even had a hiccup any time Ive run them but theres always that one time when the shop winds up on the ground in ashes.
Perhaps Ive answered my own question?
I think you have. A broken bit, or a tool sliding out of a worn collet can cause a spark, or heat up to the point that the vacuum flow can spark a fire on the spoilboard. Once the flames hit the dust extraction, an explosion is likely. I think even lights out facilities have maintenance personnel on site for emergencies. I came from a place that burned after everyone left, and no equipment was left running. The fire just took awhile to get going.
I have caught mine on fire.
I did this once, I was thinking of the machine the whole time. Might as well of stayed there with it.
Also if you do choose to do this...dont set your alarm. The motion of the machine moving will be picked up by the motion sensors haha learned that the stupid way.
I agree with the others, too risky in wood.
I have been in a couple shops that run parts lights out. 1 was a 5 axis cnc that did intricate carvings that take several hours to run. On that one he had somebody that was on call and could watch and operate remotely.
I have done it with epoxy tooling board.It became a lot less stressful when the company had a night shift and I could ask the guys to look in every once in a while.They were briefed to hit the E-stop button and call me if things looked bad.I didn't get called and we got a good amount of work done.Without a pair of eyes available,its not much fun.
Now i have a camera and only sit 20 feet away in an office, i do run it late but will pay a guy to stay to say 11:00pm then set it on pause.
I have lit it up twice, if we had not been close when the one in the photos caught it the Embers would have reached the Vac and dust collector, after that it would have fried the whole thing
ask your carrier. I am sure that you claim would be denied, under negligence in the event of a fire or machine damage
