I have not ordered a bot yet and when I do, it will be setup in my garage/shop. I experience power outages on occasion where the power goes off completely for a second or two (or less) and other times I have some sort of power interuption that registers on my computer backup battery monitor.

How does that affect a job in progress? What does it do to a spindle with a 3-phase converter.

I have complained to my power company a number of times but they do not seem to do anything. They once told me it is on there side and nothing to do with my house.

Thanks, Kevin

Kevin..
Make sure that your control computer is on an UPS. The relays in the control box will have to be reset, and you may have to learn how to start files from a given point or line. If the ShopBot computer loses power... you will have to start from scratch.

My control computer is a notebook that has a good battery. It keeps running even if the power fails.

I also had a problem with my power failing almost religously between 10am to 11am every morning. Turns out it was the new meter they'd put on my house that allows them to read the meter through the power grid. They were testing the new hardware and every morning were polling the test meters. In my case it was causing the power to turn off and right back on. Seems it is related to the feature where they can turn off someone's power remotely if they don't pay their power bill. Took some complaining but they finally swapped my meter again and the power cycling stopped.

Having the power fail regularly and expecting to cope with it during jobs as a normal routine is NOT a good plan of action. You should really get the power company to take care of the issue. It may take you keeping a power log and complaining to a State regulatory commission, but there are standards of service power companies must follow.

While I have not been having a problem with power failure, I have wondered if connecting through one of those battery backup units would allow a controlled shut down of the entire system. It would seem to me that a controlled stop would allow you the time to get the bit out of the material, shut down the router, and record line number of the file for starting back up when the power comes back on. Just a thought.

I dread the day that my router stops spinning and the Shopbot continues to move. It happened twice over the years, once when the brushes burnt up and another when the router breaker tripped. I toyed with the idea of putting a "motion" sensor of some kind on the machine that would shut the router off.
