Random block of printing

mandreas · 2021-07-25 09:50:01

hello Shahin ,

the system with official Nanodl card , so far it worked well , currently I get random print blocks , Raspberry and shield are powered independently,

thanks Andrea

Have you changed gcode/codes I think synchronization is not right

mandreas · 2021-08-01 16:53:24

I don’t know , I didn’t change anything, however I installed the latest version 4550 and so far everything is fine, thanks

mandreas · 2021-08-01 22:22:13

unfortunately I sang victory too soon : with version 4550 I still get crash in the middle of print: https://drive.google.com/file/d/150oW1U … sp=sharing

mandreas · 2021-08-02 19:44:11

probably the problem is related to resin profiles , which if derived from previous versions produce crash, but if recreated new seems to work well

vois · 2021-08-03 08:20:29

Versions 4436, 4440, 4550 stop during operation!
Version 4356 works very well. Two printers work on this 4356 version.
I wrote a letter to Shahin contact@nanodlp.com with attached files, there was no response.

Yes, I agree !! I also passed to 4356 and so far no crah has occurred

Shahin · 2021-08-04 15:13:24

I do not see indication of crash on log file nor screenshot.
Maybe it does not go to the next step right? Specifically after this line?

Can you find closer build number to make troubleshooting easier? 4356-4436

Vois,
Sorry missed your email.

Shahin · 2021-08-04 19:06:11

I have checked your printer config, the configuration being used on your printer is not suitable for very short cure times.
Move whatever you have on shutter before and after (except delay) gcode boxes to before and after layer gcode boxes.

vois · 2021-08-04 21:13:12

Thank you Shahin for your attention.
This is a test bench on which I check the work of all assemblies with the same settings. I have the Z, X, Y axes turned on.
the fact that all builds up to 4436 worked well. These 4436, 4440, 4550 stop half way.
Incorrect cure time settings did not cause stalls in versions prior to 4436.

Shahin · 2021-08-05 06:54:45

Still not 100% sure that is the cause but it is probably the reason for printer stalls.
Recent build compiled with newer version of golang toolchain, so small timing difference caused it surface on the recent builds.

Hello Shahin!
On your recommendation, I changed the values in the settings. I checked it on Pi3, Pi4 boards.
Versions 4436, 4440, 4550 still freeze.
Unfortunately, I had to go back to the working version 4356.

Shahin · 2021-08-13 07:09:43

Mandreas,

Do you still experiencing the same issue?

Hi Shahin ,

I use the 4436 and so far all good, with later versions instead it happens that it accidentally stopped , not a crash , but does not complete a pass

Shahin · 2021-08-13 17:24:54

Mandreas,

Did you tried workaround posted above on the latest builds?

vois · 2021-08-13 19:01:56

Hello Shahin!
The latest beta 4661 still freezes. Did your recommendations..

Shahin · 2021-08-15 06:44:34

Another update hopefully the issue get resolved. Still could not find why some user experience kind of freeze.

mandreas · 2021-08-15 17:20:39

Thanks Shahin ,

I’m testing the 4708 with a new resin profile and so far it’s fine , I’ll update you

vois · 2021-08-15 18:59:42

Unfortunately version 4708 also hangs. I ran it twice.

mandreas · 2021-08-18 19:56:04

Yes confirm , 4708 frezee again..

vois · 2021-08-19 10:54:01

Version 4724 also hangs.
Is that just the two of us happening?

Shahin · 2021-08-19 18:41:32

Vois,

At-least for your case I found what causing the issue. It seems firmware you are using keep sending Z_move_comp for all gcode commands, many of them instantly.
This command should be send only for movement gcodes in order to sync movement.

Mandreas,

I think your case is different and much more random, I think it is timing related. If it rarely happens you can use timeout argument on [[WaitForDoneMessage ...]]
Probably movement is zero distance/short and response being send instantly which cause response to be received before actual [[WaitForDone...]]

mandreas · 2021-08-20 19:21:09

Thank you Shahin i try that

vois · 2021-08-21 13:51:47

Hello Shahin!
Did I understand you correctly, [[WaitForDoneMessage 2.3]] is this 2.3 seconds timeout?

Shahin · 2021-08-21 14:58:06

Yes, but it is not good solution for your printer problem. You need to use better synchronization mechanism.
