Orca slicer hangs printing large files

[Oscilllator]

Is there an existing issue for this problem?

• [X] I have searched the existing issues

OrcaSlicer Version

OrcaSlicer_Linux_V2.0.0.AppImage

Operating System (OS)

Linux

OS Version

Ubuntu 22.04.3

Additional system information

No response

Printer

Bambu P1P

How to reproduce

Both the zip and .stl versions when sliced with the default 0.4mm profile of the p1p. When I press 'print' the program hangs. I don't think it is hanging just to transfer the file, I left it for 2 hours and nothing happened.

Actual results

Program stops responding

Expected results

printer should start printing.

[SoftFever]

does it happen every time?

[Oscilllator]

Yes, every time. I am attempting to split the model right now to print it in halves to get around the problem.

[SoftFever]

Might be a network issue, the log didn't show errors.

[Oscilllator]

Interesting, on startup I have been getting the message:

use system SSL certificate: /etc/ssl/certs/ca-certificates.crt
To manually specify the system certificate store, set the SSL_CERT_FILE environment variable to the correct CA and
restart the application

I wonder if this is related.

[KollegeX]

Probably related to #5273
Experience the same thing on every large gcode with 2.0 and 2.1 beta Using the Appimage of 1.8 allowed me to print

edit: linked the wrong issue

[olehmykhalchenko]

Its related to bambu network driver. Works good on Orca Slicer v1.8.1, also works on bambu studio. All newer versions of orca slicer are broken.

This is not related. You can get the same message in Bambu Studio or Orca Sliver v1.8.1, but they work with any file size.

[olehmykhalchenko]

Also important to mention this problem is not reproduced with Klipper integration. So its 100% bambu network driver.

It is happening here in 2.0 appimage. The app is hammering a single cpu at 100% and strace shows it read()ing all of the gcode as ascii.

read(86, "982.376\nG1 X198.363 Y103.503 E.0"..., 8191) = 8191
read(86, "F12000\nG1 X126.81 Y67.289 E.0101"..., 8191) = 8191
read(86, "343.004\nG1 X174.396 Y72.967 E.01"..., 8191) = 8191
read(86, "3\nG1 X200.823 Y110.183 E.00173\nG"..., 8191) = 8191
read(86, "8.264 Y159.591 E.01463\nG1 F12000"..., 8191) = 8191
read(86, "00828\nG1 X146.381 Y180.343 E.011"..., 8191) = 8191

FD 86 (and 85 for some reason) is /tmp/orcaslicer_model/Thu_Jun_20/11_39_58#2836763#269/Metadata/.2870340.0.gcode and it is 75MB.

This happens at the "pick a printer" dialog of the "print plate" button, BEFORE the "send to printer" was clicked. I'm running with an AMS, and the slicer is connected (device page) but it hangs before the filament selection on the dialog. This particular model is fuzzy skin.

Edit: Looking at the offsets, it is reading the whole thing over and over in a loop. Omitting any read(86, lines:

Also not working in new 2.1.0 release

[af7v]

I can confirm that v2.1.1 hangs on large gcode files when trying to print. Appimage on Linux. Smaller files work fine. In my case I'm trying a stacked multiboard sending to a BambuLab X1C

Opened source and sliced to a 15.3MB file in Bambu Studio 1.9.3.50 and was able to send to the printer.

Opened source and sliced to a 15.3MB file in Bambu Studio 1.9.3.50 and was able to send to the printer.

Same finding in v2.1.1 running as appimage on Linux: larger files (did not check the size limit) hang, while they can be printed with Bambulab easily. Also sending to SD card has the same issue. And, I can also confirm, that the issue already starts in the "pick a printer" dialogue, before hitting send.

[Highcooley]

Maybe the ticket should be renamed "Orca slicer hangs printing large files", to make it more generic as the problem seems to be.

[bhaal2]

Can confirm this is still an issue in current Ubuntu nightly build as of the 01/08/24 (AEST). FWIW, I can "Send" to a printer, and then print from the touchscreen (I'm in LAN only mode). But LAN only or cloud makes no difference, not sure if that's been covered in this thread, but I tried both...

[nsfilho]

The problem persists in version 2.2.0-dev. I'm using Debian 12, and if I reduce the G-code, I can select the printer and send it. However, with large G-code files, it freezes.

Is there any way I can assist in resolving this bug? If a developer could provide some guidance on the possible cause, I would be happy to investigate and try to help with a PR.

[eous]

So here is a bit that I don't see yet. I think its continuously re-reading the gcode because the printer keeps rejecting whatever handshake its trying to do.

Still not working, send dialog freezes. No problem on Mac.
