Don't think so, i set it to unlimited before and as you see at 152 htreads the printer crashed.
It crashed with the clean distribution too.

The two things i changed before it worked were:

- Try a different Raspi 3 Board
- Install image fron NanoDLP website.

the default ulimit that i have now is at around 7000 without problems.

Hi!
I did some more tests. Changed my Pi and installed image from NanoDLP Website. Now it finally works!!

For comparison, this is the statistics now:

layer 1 - 56 threads
...
layer 2376 - 93 threads

this was the stats before:

layer 1 - 24 threads
...
layer 592 - 152 threads - CRASH

So it's much better! No crashes so far.
Nevertheless the thread count is climbing, so i imagine if i left the printer on and printed 10k layer prints, it might still crash.
Although at this time it's only speculation, if the crashes were due to high thread count..152 is not much..

Anyways, all good now

adam · Bug Reports

I did just that and it worked, still no luck in crash avoidance.

Now i'm changing the hardware itself. Using official printer Image you provide on the homepage.

adam · Bug Reports

Hello Shahin,

since my crashes didn't stop, i proceeded with installing on a fresh raspbian image.
now i get the error:

./printer: error while loading shared libraries: libGLESv2.so: cannot open shared object file: No such file or directory

i've searched and found this thread:
https://www.nanodlp.com/forum/viewtopic.php?id=691

It's about aome other Pi variant. I have Rpi3. What am I doing wrong?

Cheers,
Adam

adam · Bug Reports

Both limit switch fields have the same ID, so only the last one gets saved.
If i set something for top switch and nothing for bottom switch, then nothing is saved for top.

many weeks later, here it is:

pi@adam-dlp:~ $ ulimit -u
6829

adam · Bug Reports

OK, i will investigate further, thanks. I had to do some prints really quick, so there was no time to look into it and i switched it back. Will report as soon as i know sth.

Cheers^^

Hi,
when i set the above option, then no matter what i do in Z axis control, the motor always moves down. At least it started doing so when i started a print and ran into my hard stop at the build plate. I couldn't move it up anymore.

I set it to "Ënable on boot" and it works normally again.

This is what the log says:

sure, i will send you as soon as i'm back home and the pi is running and try the command

unfortunately it crashed again after 675 layers:

adam · Bug Reports

I only got "runtime/cgo: pthread_create failed: Resource temporarily unavailable" so far, will try some long prints with the new version and see what happens

adam · Bug Reports

What do you mean by Net keyword?

adam · Bug Reports

nice, thanks. I will try syscall in shutter before moving to GPIO.

adam · Bug Reports

hi Shahin,

i haven't noticed anything strange. it's 1round 17 processes. Yes, still syscall but in the last versions there were no problems.
Thought that this might be an issue with the new version.
I am trying to go away from syscall and do the projector LED via shutter GPIO pin in the future.

Hi,

unfortunately i got a crash after 800 layers on ver 1524.

adam · Bug Reports

as a side note, it would be really interesting to see a sequence diagram of all the actions during print.

adam · Bug Reports

Hi,

contrary to previous versions, now with 1524 the syscall "before each layer" is done before the axis moves down. is it intended?

previously:

..... -> syscall before -> expose -> syscall after -> move up -> move down -> .....

now (v 1524):

..... -> syscall before -> move down -> expose -> syscall after -> move up -> .....

cheers^^

adam · Tips, Tricks and Tutorials

do you use it? does it work well?

adam · Everything else

Hi shahin,

I've recently run multiple 12+hours prints and even with external command execution, no problems whatsoever!
In the name of the comunity, thanks again for this outstanding piece of software!

Cheers!

adam · Feature Requests

Thank you!!

adam · Feature Requests

Heyho,
this may seem like a small feature, but could save some clicks during preparation.
Would it be possible to auto-name the plate by filename? just pre-fill the "name" field:

plate_xyz.stl -> plate_xyz

i always keep my filenames tidy for archiving so there is no need to rename the plates. I don't know if others would profit from that feature though..

cheers^^

adam · Tips, Tricks and Tutorials

It's the projector. Quite expensive, but every pixel is usable, and it has intergrated precalibrated mask.

Lots of new pictures and information

adam · Feature Requests

thanks!

adam · Feature Requests

exactly, for a simple version you would not need to have knowledge about volumetric structure. You could solve this by using the existing dimming, but instead of dimmed pixels just overlay a static hexagonal pattern. It won't be pretty but it would do it's job. getting the resin out is a pain though. A every hollow pillar is closed, you would need one hole per cell which is not practical when using a simple infill.
