Hi!

I have an A10M printer and yesterday the board suddenly died. I have been cleaning the hotend and after the assembly, when I turned on the printer the display started for a second and turned off.
Checking the board I have found a blown fuse (the 10A one), so I want to test if the board is still alive before buying the new fuse.
How can I test the mainboard? Any way to power it via usb to test if the atmega responds?

Any help is appreciated!

Hi, you can connect the printer to the slicing software via USB,
See if you can control the printer.

Thanks for the answer William!
No, mi computer isn't detecting the printer.
I guess the microcontroller is powered via the 24v power source, and without the fuse no current reaches it.
No leds are turning on in the board at any moment.

Edit: I have tried to connect the good fuse replacing the blown one. Y kept everything disconnected except the display. When powering on the printer, the display and the board are working fine. So I will get the replacement for the fuse.
Now I am questioning why this fuse has blown. I have made a shortcircuit in the resistor or the fans in the hotend? Or maybe is something else what im not seeing?

Hi,may be caused by poor contact.

Hi.
I have checked all the cables and connections at the hotend and everything looks good, it's really strange.
I will test the connections to see if everything is ok before powering the printer and I will post the results.
