Ender 3 Power Problem: Not starting up

4

I have a Creality Ender 3, I've had it for just under 2 years and during a print one morning it suddenly stopped and powered itself off. After checking the fuse and other electronic components it still didn't power on. I purchased a new switch as I thought the problem was there but after replacing it is still did not turn on.

The printer has been working fine and there were no visible or audible anomalies. I urgently need this to be fixed.

2This might be a broken Power supply as much as a broken board. To test: keep the mains power unplugged, connect the front USB port to a PC. If you get a screen, the board is ok. Just get a new Power supply in that case. – Trish – 2019-10-18T09:46:00.837

Ok, I will try that. – Tim Li – 2019-10-18T09:54:57.310

Is anything abnormal here: the power supply? – Tim Li – 2019-10-18T10:16:39.650

I am not an electrician, but the 8A/230V fuse of the Power supply seems to be intact. Do NOT work with mains voltage unless you have undergone the necessary training to do so! Take all the necessary precautions as you need to work with electricity under mains voltage! Thomas has a tutorial on what might be needed to repair them. https://www.youtube.com/watch?v=gHBpDxf6eVA

I think it may be wise to invest in a multimeter, you would then be able to check if the PSU outputs 12/24 V (depending on the output voltage).

1Does the outlet that you're plugging it into have power? (Yea this happened to me once with my Anet A8) – user77232 – 2019-10-18T13:53:12.853

@TimLi When you buy a multimeter, note that although many 3D printers work from 12 V (as mentioned by 0scar), an Ender 3 uses a 24 V PSU. A convenient place to measure is found by disconnecting (with the PSU switched off) the yellow connector. – Andrew Morton – 2019-10-18T19:50:13.977

Purchased new power supply after testing he board. Thanks for your help. – Tim Li – 2019-10-21T20:35:53.140
