Problem caused by power glitch

[redwood]

I'm making a sign for a client from his 50" x 20" cedar slab. Everything was going fine. I pocketed the slab where needed and had run a rough finish path. About 1/2 way through the 3D finish path there was a power hiccup and the spindle stopped spinning but everything else kept going. When the hiccup happened, I looked from a distance and everything looked like it wasn't affected. A little while later I got closer and saw that the spindle wasn't spinning a just dragging the 1/16" tapered ball nose over the model. Well that sucked, to say the least.

So how do I fix it? I'm thinking that I can just set the gap above the model a little greater and that would go back over everything just a little deeper. Does that sound right? Any other ideas?

That should work.

You might check out this thread to prevent it from happening in the future. http://forum.vectric.com/viewtopic.php? ... 54#p155254

I've used this trick since my original post and it's saved me several times.

Thanks John, your fix is probably a little technical for me. My whole system runs off of a 220V supply line and my spindle is a 3 HP unit. Normally something like this wouldn't concern me. 99.9% of the time, I'm suppling the materials and the cost to replace would be minimal. This was a good size slab.

It's not so funny, but I knew we were going to have a extended period of bad weather when I won't run my machine. I was planning to stop before running the 3D finish toolpath and continue when the weather improved. Well at the last moment, I decided to push on and try to finish it. It would have been done about 2AM. The hiccup was literally a flicker. We have had over 3' of snow in the last 1 1/2 weeks, in a area that get's about a foot a year. In the middle of that, we had 5" of rain. Without that rain in the middle to melt the first batch of snow, I probably would never get out of my place.

That sucks. The same thing can happen to me as my control system is on 120 volts and my spindle takes 240 single phase and through a VFD. Some VFD's and I think mine has it, have an output so if the drive faults out for some reason it can trigger the controller to shut down and stop running the program. I have an Hitachi something but its rated at 3 Hp.
