2255 hangs in the middle of the print

Is there some more descriptive log perhaps, where I could see the reason?..

It just suddenly "hangs" during the print (configuration with the Raspberry Pi + RAMPS board).

First time it hang on the level 11 with LEDs on, curing this level indefinitely, and after switching on the LED there were no "Curing for X seconds" record appeared in the log, it just continued to be curing indefinitely after switching on the LEDs... The "Stop" buttons did not do anything, it still continued (but UI was still responsive)... I was forced to switch the printer off to stop it.

Next time it hang on the level 8, immediately after "Shutter close" record: the LEDs went off this time, but after that no new records in the log, and it hang in this state indefinitely... Stopping it did not work too, so I was forced to hard-reboot it again. But the UI itself was working, so it was not a printer process crash or full-freeze...

It worked OK on the same printer with previous versions I tried...
Just let me know if you want me to debug it on my end somehow.

Re: 2255 hangs in the middle of the print

Ah, found a printer.log file with some more info than in the UI. Don't see the "attach file to the post" functionality here, so here is the part of a last log around the layer 8 (where it got stuck). I tried to use "Stop" and "Force stop" buttons with no effect, so perhaps the "Using this function during printering is forbidden" lines may be a result of it, but maybe some other reason...
BTW, it did not move the platform up/down between layers during printing in the "out of the box" installation of NanoDLP (despite the fact the "lift after print" values are stated in the profile), so I was forced to add the "before" and "after" GCODE manually to the profile, is this normal?..

Re: 2255 hangs in the middle of the print

I also experienced a crash mid print.

Re: 2255 hangs in the middle of the print

I see in the log I've posted here that the printer process is crashed by the assertion in imageLayer.c somewhere around the time when the [[Delay 0.5]] command I have in my "before layer" and "after layer" gcodes is executed...
So I've just removed the [[Delay 0.5]] from both "before" and "after" - and so far so good, it is printing right now the layer 35, fingers crossed so far haven't crashed...
So there is definitely some nasty crash bug asserted on the line 255 of the imageLayer.c...

Re: 2255 hangs in the middle of the print

Oops, I wrote too early... It just crashed immediately after I posted my previous message - exactly at the layer 35. wink
So, the [[Delay 0.5]] was nothing to do with this crash bug - it still crashes inside imageLayer.c...

Re: 2255 hangs in the middle of the print

Just tried to

sudo apt update && sudo apt upgrade

and started the printing again.
Right now it is printing the layer 61, and so far is still alive... wink

Will let you know how it ends up. If everything will be OK - then it might be the bug somewhere in the system GPU-related code which could have been fixed by the Pi system update/upgrade...

Re: 2255 hangs in the middle of the print

Nope.
It did the same crash at the layer 101. But this time there is no crash stacktrace in the log, it just silently died with the LED matrix switched ON (and without the next "Curing for X seconds" record in the UI log). So I did a hard-reset again, 'cause it doesn't react to any "Stop" buttons when this happens.

So I can't use it in this state - it's not possible to leave it printing without sitting and watching it all the time...

Re: 2255 hangs in the middle of the print

Maybe two issues are mixed. One is fixed with the firmware upgrade.
I guess the second issue is power related. Check if you are supplying stable power to pi.

Re: 2255 hangs in the middle of the print

Thank you for the advise!

The power supply is OK: it has twice the needed power (including UV), and it worked absolutely OK before...
But I agree that it looks like some hardware issue too: such random failures at different times often end up to be some GPU or CPU overheat... So, I've already ran one more test today - I've lowered the pixel frequency of the screen, and 267 layers printed without any problems and no freezes. I stopped it because it's late here (NZ), I'm going to bed already - don't want it to print unattended so far...
But tomorrow I'll run the full test: if it will not have any freezes, then it most likely was some kind of overheat or other hardware issue that looks like got resolved by lowering the frequency.
I'll let here know tomorrow if that solved the issue.

Re: 2255 hangs in the middle of the print

The full test went without any hiccups.

So, it was definitely some mixed issue, thank you Shahin.
The first issue (GPU code crash) had been fixed by the system update/upgrade.
The second issue has been fixed by lowering the screen pixel rate (hdmi_timings setting in /boot/config.txt).

So guys, if you experience freezes mid of the print - update/upgrade the system, and if that doesn't help, the stuck screen (GPU) hardware might be the reason of freezes - try to lower the pixel-rate, or ask the screen supplier for the exact hdmi_timings for that particular screen...
