A10 suddently died during printing

[david-77]

Hello everyone,

I bought the A10 a few months ago (april, must be V3), and until last week I only printed 2/3 small objects for testing (like 30 minutes printing)
Last week I tried for the first time a long printing (10 hours estimated) and the A10 suddently died after 2 hours.
I tried to power off/power on using the switch button, and the only sign of life I have is the switch beeing red enlighted : no fan, no screen, everything else seems ofF.

I send a message to the Geeetech support (and the seller) last week right after the incident, but I did not have any reply yet.

What can I do ?

Thanks for your help.

I had similar problems with my A10M. It died during print. I had faulty heating cartridge in my hotend that caused short in my board. 100% your 10A smd fuse is blown out.

Thanks for your response.
Just changing the fuse would be ok ? Or do you think the board died completely ? Or, if I understand correclty with my little knowledge in electronic, changing the fuse would just give me a little bit of time before the problem happens again ?

You need to find out what causing short and replace this element. In my case problematic heating cartridge was easy to figure it out because when I tried heat up hotend instantly fuse blow out again. I replaced heating element and fuse. Now everything is working perfectly. In your case it may be something different but I would check this in first place.

Ok, thanks again !
I guess I have to open the power supply to find this fuse...

Fuse is located on mainboard

Let me know what kind a mainboard you have v3.0 or Rev B.

Hi， You can check when you turn on the printer,
Are there three lights on your motherboard?
You can refer to this:

Hi everyone

Thanks for the picture and the test to do, too bad I read this message after opening and closing the box containing the motherboard. I'll try this tonight.
I have taken a picture too, I can confirm it is a V3, and I check the 2 fuses I found, and they're good...
Maybe it's the power supply ? The fan in the power supply doesn't work, and I remember that before this issue it was the first sound I heard when I powered on the printer.

@William,

So I tried to power on the printer, and no lights on the mainboard. Only the power switch button on the power supply gets enlighted.
What do you think ?
