Can not display thumbnail after add MMU_START_SETUP MMU_START_CHECK to start g_Code #263

zhangxiaokang7788 · 2024-04-09T12:16:46Z

after I add MMU_START_SETUP、 MMU_START_CHECK to start g_Code like this:

MMU_START_SETUP INITIAL_TOOL={initial_tool} REFERENCED_TOOLS=!referenced_tools! TOOL_COLORS=!colors! TOOL_TEMPS=!temperatures! TOOL_MATERIALS=!materials! PURGE_VOLUMES=!purge_volumes! ; Initialize MMU and save info from gcode file
MMU_START_CHECK ; Check MMU is setup for the slicer defined print
M115 U3.9.3 ; tell printer latest fw version

My thumbnail can not display.I use Orcaslicer and fluid.Refresh meta does not work:

CUBE_PETG_1h1m.gcode.txt

moggieuk · 2024-04-09T19:14:56Z

Does this occur with every gcode file you upload? If you have a small gcode file that has the error, can you attach to this issue. Inspecting it might highlight the cause...

zhangxiaokang7788 · 2024-04-10T02:58:15Z

Every time when I upload the same test g-code. It is two cube model，and did not test other model.It goes all right when I delete these G-Code .So I think herein lies the problem.

I have updated the comment , thank you for your answer.

moggieuk · 2024-04-10T04:05:30Z

Very strange. The file you sent has not been pre-processed by Happy Hare - I assume it is the original file.

I loaded into my system with HH pre-processor enabled and it correctly parsed the placeholders and Tx tool changes: E.g.

I can see the thumbnail in Mainsail, shown below...

moggieuk · 2024-04-10T04:08:09Z

So I don't understand why the thumbnail is not displaying.. on my system it displays both before the HH pre-processing and afterwards.

Also the diff above shows that the only parts of the gcode file changes are as expected -- the thumbnail image is exactly the same...?

ningpj · 2024-04-10T04:24:46Z

Could be a browser caching issue....try clearing your cache and refreshing your mainsail window as your gcode thumbnail displays fine on my system with Fluidd

zhangxiaokang7788 · 2024-04-10T04:36:20Z

Yes, I compared the two G-code files and the thumbnail part is exactly the same. So I do not know why.

The printing state can not display too which is showing in the second picture.

I clearing the cache and refreshing my fluid window ,it can not display too.

zhangxiaokang7788 · 2024-04-10T05:29:42Z

It goes right when I enable pre-processed by Happy Hare. Is that necessary.

enable_file_preprocessor: True

ningpj · 2024-04-10T05:56:42Z

if you are using placeholders like REFERENCED_TOOLS=!referenced_tools! then yes. However I'm not sure why having Happy Hare enable_file_preprocessor: False would cause mainsail/fluidd not to be able to render the thumb nail though.

I just loaded your gcode with out preprocessing the placeholders and it was displayed fine even with double byte characters on Pi's setup for english users (e.g. LANG=en_GB.UTF-8)

moggieuk · 2024-04-10T10:29:36Z

I'll check with HH pre-processing turned off but I can't imagine this would make a difference...

Edit. I've tried all sorts of cases with your gcode file including with pre-processing turned off. It works every time!

zhangxiaokang7788 · 2024-04-12T12:36:32Z

The problem troubled again,even if I enabled file preprocessor.There is an error in moonraker log file .It take too long for preprocess.Is my machine underperforming:

moggieuk · 2024-04-22T03:08:47Z

That's interesting. The pre-processing that HH adds is much smaller (overhead) that the native "object" pre-processing that moonraker can add, but an error could cause the issue you describe. Do you have a fast SD-card? One thing that does occur during pre-processing is a lot of sd-card read/writes...

zhangxiaokang7788 · 2024-04-23T06:48:47Z

Yes,It works very well without SD-card.I will test for more time.My SD-card is very old.

deathfrozen · 2024-04-30T23:43:33Z

I have this problem with very large files (30 mb or more). Such files are often obtained precisely because of multimaterial printing and do not allow not only to view the thumbnail, but also other valuable information is lost - for example, the layer number, and sometimes the preliminary check of the presence of the thread before printing does not work. Is there no way to increase the file processing time?

deathfrozen · 2024-05-05T23:00:55Z

I tried to transfer my system to a usb ssd drive and it didn't help, although the testing speed increased 20 times. I tried to disable enable_file_preprocessor and got a more distinct error -

File "/home/orangepi/moonraker/moonraker/components/mmu_server.py ", line 264, in main
if (insert_nextpos and lean(tools_used) > 0) or has_placeholder:
TypeError: object of type 'NoneType' has no len()

I tried to delete the link to mmu_server.py in the moonraker catalog and metadata are scanned and everything works - both the thumbnail and other parameters.

I am not well versed in python, but in the code earlier I see in the else condition the assignment of tools_used None, but there is no check before using lan(tools_used). Is it possible that adding a check to None will avoid this error?

if insert_placeholders:
start = time.time()
has_placeholder, tools_used, colors, temps, materials, purge_volumes, slicer = parse_gcode_file(file_path)
metadata.logger.info("Reading placeholders took %.2fs. Detected gcode by slicer: %s" % (time.time() - start, slicer))
else:
tools_used = colors = temps = materials = purge_volumes = slicer = None
has_placeholder = False
if (insert_nextpos and len(tools_used) > 0) or has_placeholder:

zhangxiaokang7788 · 2024-05-06T04:35:41Z

I got this problem with a large file too.

salocain · 2024-05-12T16:40:40Z

same problem

and many "time too close " or "crash"

deathfrozen · 2024-05-15T10:53:12Z

I've done some research and even some debugging. As a result, it turned out that adding

[file_manager]
enable_object_processing: True

to the moonraker.conf file solves the problem with processing large files. This is due to the fact that in moonraker, with this option set, the timeout is 30 times longer.

I didn't figure - how to set a timeout from a file mmu_server.py or out other options in the configuration files, and it's likely that it's impossible with the current moonraker code.

The error I wrote about earlier - #263 (comment) it only occurs when the option
is set enable_file_preprocessor: False. I've made a simple fix and I think I'll try to create a pr (#294).
