Anyone know what the load current is for the spindle and machine. I would like to size a UPS to allow me to keep my “place” in the carving when I get a power loss during cutting. I want it powered long enough to be able to pause the program and power down the spindle and just keep the controller settings so I can restart when the power is restored.

We seem to get our share of momentary blips here in Florida and the rainy season is coming......

Can’t find my ammeter :oops:

If I am not mistaken, the NWA spindle is only 110V, so you can look on Amazon for a power supply. I don't think they are very cheap, but probably wort it if your electrical service has glitches. I would make sure it's over sized to be on the safe side.

Running a Pocket toolpath with .125 End Mill on Foam - 100IPM
Everything running - 120v:
Shark HD4
H2O Spindle
H2O Pump
Led light - 12v 1Amp Transformer

The highest Wattage seen was 167 Watts

Thinking that if cutting more than foam it might be higher.

Edit - 12k RPM
When I increased RPM to 17k it jumped to 172 Watts
Roughly 1.5 Amps
