What are possible reasons for printer going crazy and power reset itself during filament change? Happened after upgrading firmware 3.10.1

Hi, I have been using an i3MK3S+ for 2+ years without power issue but for the past two days, during filament change of M600, the printer sounded a loud beep and reset by itself. Then it restarted automatically and used power recovery mode to resume the print jobs. In both cases, it asked me to unload and reload filaments. Both print jobs are different and each has about 10 M600 but in both cases, such power issue happened in the middle of a series of M600 only once. Don’t recall yesterday but today after power recovery, the LCD shows garbage characters. What could be the cause for power issues?

Usually in the winter, my LCD screen shows garbage characters often. Not sure if this is the cause. I upgraded the firmware to 3.10.1 two days ago. Anybody has similar issue after upgrading the firmware?

It sounds like a loose or broken connection.  Time for a general wiring check - is anything loose?

Cheerio,

Thanks for the suggestions. I checked the wires while the printer was on. Noting unusual was found.

Power failure

Two more power issues today. The first one happened after hearing it beeped twice I pressed the knob next to the LCD screen to change filament (due to M600). When I pressed the knob, there was a long beep and the printer went crazy and moved the extruder to the home position. Then I unloaded and loaded filament. It resumed print. The second time happened in the middle of the same print. I noticed wrapping perhaps due to the cold weather. So I stopped the print job and removed the PEI sheet. As I removed the sheet, printer went crazy and saw a message like power crash or print crash. Then, the machine rebooted itself. 

While the printer was on, lightly moved the cables around but again, the printer was still on so there is no loose connection.

 

I checked the failure stats on the LCD and found:

Power failure: 7

X15 Y19

Don't think it is related but I did a belt test and the values are: X230, Y277.

RE:

OK, it really does sound like a poor connection in the power line or between the power supply and the Einsy. Time to try swapping out potential culprits: try a different mains socket, a different power cable, recheck the power connections to the Einsy and the connections to your print bed.

There is a small possibility that you have mains issues and that a brownout happened to coincide with your actions but it is extremely unlikely.  The other, almost as unlikely, possibility is that some other appliance nearby is failing and putting noise on the mains power lines.  Place a mains powered analogue radio next to the printer and you may hear interference, crackling or sudden silence if the external power is at fault.

Cheerio,
