Print/Send dialog hangs and thread(s) goto 100% on larger models.

[nick-laird]

OrcaSlicer Version

1.9.0 and greater (also happens in nightly)

OS version

Linux

Additional system information

Two systems both running Linux, one Arch other Ubuntu. One is a Celeron 4x core. Other is a Xeon 8x core. Celeron has 8GB RAM, Xeon has 64GB.

Printer

Bambu X1 Carbon

How to reproduce

1. Get a fairly large model or models that will take a bit of time to slice.
2. Slice them so the resulting file is over 10MB
3. Try to direct send or print to printer using the network plugin.
4. It works in 1.8.1 and freezes in later versions as the threads get stuck @ around 100%.
5. sometimes I can click cancel and wait and eventually the dialog closes. other times it doesn't and I have to force terminate the app.

Actual results

Expected results

The dialog should stop saying "Click Here if You Can't Connect" and should offer AMS, Bed leveling, etc checkboxes. Clicking Print should then start the transfer to the printer.

Project file & Debug log uploads

This appears to be one of hte possible issues. After it does a PrintStatusInit() after I clicked "Print" it starts dumping: 2024-01-29 11:19:27.059810[Thread 0x00007003c3945480]:The values of tray_info_idx and tray_type do not match tray_info_idx tray_type system_type Over and over again.

Orca bot: this issue is stale because it has been open for 90 days with no activity.

[nick-laird]

Still exists in the 2.1.0-dev nightlies.

also present in linux mint wilma with orcaslicer 2.1.1

trying to print a simple cube works fine, but a larger/complexer print hangs highlighted the fields which are strange

model that triggered it https://www.printables.com/model/936619-dice-tower

edit:

• 0.28mm or 0.24mm works as expected
• 0.20 takes a while and then it will work
• 0.16 doesn't work, i gave up after 15 minutes or something like that

if it matters, because it seems a time related thing: AMD Ryzen 7 PRO 4750U with 48gb memory and a wired connection to the network

edit2: the generated 3fm file is 10mb in size, it feels like it has something to do with the bambu cloud

[real-artswan]

confirm with 2.1.1 Ubuntu 22.04.4 LTS, somehow larger models makes the dialog hanging

[tak-21]

Same problem here.

• Linux mint v22
• OrcaSlicer v2.1.1
• OrcaSlicer Ubuntu2404_V2.2.0-rc

When I slice one "ghost" (see attached stl) the "Send print job to" dialogs just works. If I clone the object, hence add a second ghost the dialog "Send print job to" hangs/is not usable.
