In the middle of a print I had a power outage due to a thunderstorm. The printer is on a surge protector.
Now the printer is basically DOA. The screen does not come on, Bambu Handy can’t find the printer. The power switch light is on and the AMS lights are on, but the printer won’t come on etc.
Any ideas?
Sounds like a fried MC board, but I don’t know what the test procedure would be for that. The fact that the light comes on suggest the mains are powering the printer but no display or WiFi tells me one of the boards are malfunctioning. Sometimes when a board goes out from an overvoltage you can get a quick tell by checking for blown capacitors (the cylindrical pills on the circuit board). Either way, I can’t imagine the boards are too expensive (MC or AP boards), so open a ticket and a get your spot in line for some help and new parts.
I’d also get a new surge protector.
I opened a ticket and the first response was to test the voltage output of the power supply (24v). The power supply reads 24v so that’s good.
Examining the boards I don’t see anything obvious, but I also don’t know if a blown capacitor will be easy to spot?
Yeah they all look intact.
Does anyone have any more insight? This is quite frustrating and support is super slow.
I have read a disturbing number of reports of very similar occurrences with many X1C and P1P printers. And what’s worse, it seems to take a MONTH before a replacement board is sent, which is totally unacceptable.
The 24V supply doesn’t feed the logic board its power, there’s a regulator or two somewhere that drops the 24V to the lower voltage the logic requires (probably 3.3V) with maybe some 12V and 5V generated for any components that require it. If I was go guess, given the 24V supply is working, there’s a regulator somewhere that’s fried.
Do you smell burned electronics? Note: a failed regulator doesn’t mean a burnt out part, but if you get that burnt-circuit smell the bad part may be easy to spot.
Contact support again and ask them if where the regulators are, and how you can test them.
I never noticed any burned smell. I’ll do as you suggest and see if support can tell me where the regulators are.
Does anyone know if the AP board has any little LED lights that are supposed to light up when powered on?
