Failed to upload, CRC is different
-
@gruna-studio
I was able to remove the SD card and manually copy it over, but that isn't a viable long term solution.
Should also mention that with enough power cycles and reconnections of the browser I am randomly able to get the file to upload.
-
@that-guy-e I don't think that CRC error is anything to do with the SD card, because the CRC is calculated before the data is written to the SD card.
How large are the files you are trying to upload? If you can make one of them available on Dropbox or Google Drive etc. then I can try uploading them here to see of I get the same problem.

I only get the error when trying to upload a job or if I select upload and run. I haven't seen it any other time.
I'll send the file and details tomorrow. I've definitely upload larger files to a duet 2 before. I'll also retry uploading one of the smaller test files I was running the other day.

Which slicer is doing the uploading?
-
I uploaded three example gcodes here:
Google DriveThe files range from 1.8mb to 85.7mb all failed to upload. The large file is a gcode that I've successfully uploaded to an alternate Duet2 over wifi without issue.
Anything else I can provide please let me know.
-
I've tried gcodes exported from numerous slicers and cam software. And have uploaded the same files to duet2 wifi without issue.

Thanks, I'll try uploading those files to a couple of MB6HC boards.
There was a known issue in this area in early 3.0 firmware builds, but that was fixed many versions ago, well before version 3.3.

If its of any value, I'm currently running DWC 3.3.0

@that-guy-e I can get CRC errors sometimes using the large file in that collection. I will investigate this.

I've tried a few more different uploads today and I'm getting the error sometimes. seems to be "random" I can get them 2X in a row and then on the 3rd try it will work.
Has there any more investigation into adding the auxiliary SD card. this would be beneficial for scenarios like this or network errors in general.

@that-guy-e I have found and fixed the error with uploading files to the MB6HC. Please try the 3.4.0beta7+1 binary at https://www.dropbox.com/sh/5ubjszy9fmlvzwu/AAAeOMGP-Yi-Gn9LZwQoPfita?dl=0.

Sometimes i have the same problem with a Duet2 Ethernet. Is that fixed too?
But this happens not very often... -
@cosmowave I don't think the issue I found will affect Duet 2 Ethernet, although I think it will affect Duet 3 Mini Ethernet. However, I have put new Duet 2 builds there as well.
-
Seems to have solved the error. Tried 10 different file uploads without issue. I'll report back if I see any further errors but won't get to do much testing over the upcoming week.
-
I have not run into further upload error using the beta firmware you provided.
