Welcome to the SeeMeCNC Community

I'd been getting amazing prints out of my Artemis, until the past week. All of a sudden, every print over 1 hour long is spoiled by repeated under-voltage events. Troubleshooting steps I've tried so far:
Disconnecting the panelDue with no improvement,
Slowing down the print with no improvement.
Turning off the fans with no improvement.
Tried same print with 3 different slicers (Cura, Simplify3d and Kisslicer)

I also have my printer plugged into a UPS and there isn't anything else connected to that wall outlet.
By spoilt, the most common effect is the prints shift and starvation

The log reads line after line of VIN under-voltage event anywhere from 9.7-10.0v

anyone have any ideas?

Power supply is prolly going out.

It could also be that the fan or fan circuit in the power supply failed and it's overheating.

Thanks, I'll replace the power supply.

Glad it's something simple.

I don't know what PSUs SeeMeCNC supplies with the Artemis, but it it has a 115V/230V selector switch and your mains is 115V, check that the switch isn't set to 230V.
