incomplete gcodes upload

Tinchus

Hello. I have had some cases where the print stops and it is reported as finished.
But I downloaded the last gcode showed that error and I found the gcode it is incomplete. It is just not compelte. Somehow the uploaded file was cut and part of it was just lost.
Since this has happened to me 3 or 4 times I guess there is something wrong somewhere.

Is there any other similar reports? What can be causing this incomplete upload?

@tinchus in the latest firmware there is a CRC check run on uploaded gcodes. Because you are using SBC mode I am going to ask @chrishamm if there is any specific things he would like you to test.

I assume you have downloaded one of the incomplete files and confirmed that it is truncated?

@Tinchus When you get a partial upload, please use:

journalctl -u duetwebserver

in a console window on the pi. This shows the DWS log which may contain further details about why the G-code was only partially written

Tinchus

@t3p3tony Yes, I downloaded it just to check and I saw it was not complete, so basically the print finish report was ok, the problem is the truncated gcode file

Tinchus

@t3p3tony

Ok, I have done that command and created this log file. File attachedlog_duetwebserver.txt
The content of that log file is way outside my knowledge to see if there is something wrong. I saw some warnings about a service not started?

@tinchus what time did you do the upload that ended up being incomplete?

Tinchus

@t3p3tony In the DWC time says it was uploaded at 2:59 PM on 24th (yesterday)

@tinchus thanks.

It looks like a reset/emergency stop was called at 14:59:

Oct 24 14:59:13 PU-HT-1 DuetWebServer[634]: Microsoft.AspNetCore.Routing.EndpointMiddleware[0] Executing endpoint 'DuetWebServer.Controllers.MachineController.DoCode (DuetWebServer)'
Oct 24 14:59:13 PU-HT-1 DuetWebServer[634]: Microsoft.AspNetCore.Mvc.Infrastructure.ControllerActionInvoker[3] Route matched with {action = "DoCode", controller = "Machine"}. Executing controller action with signature System.Threading.Tasks.Task`1[Microsoft.AspNetCore.Mvc.IActionResult] DoCode() on controller DuetWebServer.Controllers.MachineController (DuetWebServer).
Oct 24 14:59:13 PU-HT-1 DuetWebServer[634]: DuetWebServer.Controllers.MachineController[0] [DoCode] Executing code 'M112 M999'

That cancelled the file upload - was that automatic or commanded from DWC?

Tinchus

@t3p3tony I did the upload, Im sure I didnt reset the machine while uploading.
For the uoload I used the buttom "UPLOAD AND START"

T3P3Tony

@tinchus thanks for confirming that.

@tinchus I could discover this in your log:

Microsoft.AspNetCore.Server.Kestrel.Core.BadHttpRequestException: Unexpected end of request content.

So it seems like something cancelled the upload request before it could finish. Can you try to upload something from a different device or using a different browser? If not, please try to upload something in incognito mode.

Tinchus

@chrishamm the real problem here is that if something cancelled the upload... I was never told about being cancelled. I got the normal green message pop up saying upload successful

Tinchus

@chrishamm Any suggestion on how to test? Im using firefox, so I can use the private mode. Also, this problem is not happening all the time, I have not been able to reproduce the error today
