Hello,
I'm running a Duplicator 7 on a Raspberry Pi 3 B+ and have been running into the following error on the last few prints on build 1852. It happened as well on a previous build when I reverted in attempts to fix it.

72dfebd0: 00000001 76fd22d0 006e6000 138bee98 It seems random--I've run into it on a different layers (between 200 and 350 of ~1400) of the same plate on the same profile. Conveniently, it always occurs when the LED is on so it makes a mess if I don't catch it quickly.
Before today (my first use after nanodlp upgrade to 1852 and a general update to the rest of the pi), I had never encountered this error. I can't seem to find anyone else having run into this either...
Does anyone have any recommendations for where to start?
Plan B is to wipe the card and start fresh, which wouldn't be all bad.
Thanks!

Hi, this part of code has not changed for the last 2 years.
How many times it crashed? Also is it display layer correctly before crash? Do you have any power supply and spare pi around to test?
Offline
Thanks Shahin! It's good to know that it isn't likely a code issue and to start looking for hardware failures. I will try first with a different power supply (current one is 2.5A "CanaKit") and then with a different pi. I'll report back after.
This has happened only 3 times, but all consecutively and with no failures prior to yesterday. I don't yet know if the displayed image is correct. I believe it is, but I haven't pulled off the vat after the failure to be sure. I'll report on that too.
Thanks again!

Alright, I swapped both the pi and the power supply and ended up with the same failure on layer 28. I will just reinstall everything tonight after work and try again.
I couldn't see if the layer was being displayed last time since I couldn't remove the vat with the build platform held in place on top of it. Next time I won't be so optimistic as to have a vat of resin involved in the experiment...
Thanks!

Well, I did a re-flash of the base nanodlp SD card image and it all works again. It doesn't help to answer many questions if anyone else runs into this, but it is back to being reliable again.
I will eventually try to upgrade the software again, but for now I have some things to make.
Thanks for the help!
