Power outages during operation

After much research I’m about to place an order for a Woodworker. I have one question for the group. I live in a rural area and during the summer months we have a lot of lightning. This results in momentary power outages. Does the Onefinity controller have a feature that will allow you to resume a cut after a power outage or must the cut be restarted from the beginning?

Hey Peter,

No , if your controller loses power it will essentially reset itself back to first boot. However if you use the XYZ Zero you could restart your carve and while it will carve a bit of air as it repasses over the already carved areas it will pick back up once it gets to where the power cut out and will continue as expected.

The machine is incredibly accurate and repeat operations are one of its strong points even if that’s after a restart. Again make sure you zero your work (I would recommend not even un-clapmping it as you might inadvertently twist it on the re-clamp. But if it does not move it will be perfect.



OP, hope you dont mind if I add to the question… What if the controller is on a UPS but the main power is not. How will the machine behave in a power outage?

A quality UPS (Uninterruptable Power Supply) will keep everything running for a short time. I have the same issue of the power flickering when the weather is bad. When it happens, I have enough time to plug into a generator to keep everything running…
You have to do what you have to do!

The machine will continue to move in X.Y an Z axis without the cutter turning which will likely lead to a ruined part and possibly a broken bit. If you can’t put both on UPS I wouldn’t put just the controller on a UPS, it’s better to let it stop when the power goes out and zero it and start over when the power is back IMO.

So the controller doesnt sense (lack of) current through the router and stop? Seems like a design issue.

Rural power. We get power flickers pretty regularly. Putting UPS aside for a moment…

When the power comes back, as I understand, the router will have power restored, and will begin running again.

When the controller’s power comes back online, will it leave the router in place (running), or lift it out of the project by default (zero/home)?


When the power comes back and the controller boots up it will have a prompt asking you if you want to home the machine. It will not move until you tell it to.

You could use a NVR (no voltage release) switch. Something like this
POWERTEC 71354 Magnetic Switch 120V | EZ Surface Mount Box, Other https://www.amazon.com/dp/B07HWRVPRR/ref=cm_sw_r_cp_api_glt_fabc_61J5WEA2WMGWSY7V8HWV?_encoding=UTF8&psc=1

This looks good. Let me poke around a bit to see if I can find a 220 version

Thank you

For 220 this one might work. Bit more money but looks right.
