Gcode upload inserted random characters into gcode file #97

Closed ju-sti closed 4 years ago

ju-sti commented 4 years ago

The printing of a job stopped suddenly today with this error:

I uploaded the printed gcode file with dwc to my printer. After I downloaded the gcode file from the printer to check what is wrong I noticed the issue immediately:

The original file as created by Cura has proper content. Hostname of the RPi where dwc2 for klipper is running is "raspi-print".

So I very much suspect that either uploading or printing the file in dwc has corrupted the file by inserting weird bytes and the hostname for some reason.

I'm using dwc2-for-klipper version with the "add mutex to gcode ecxecution. try to fix the one command behind" change
Uploading the gcode and downloading it again did not lead to the same error. The file did not have changed content as far as I can see.

okay thats odd. i was not able to reproduce this.

I tried today to provoke this using a pi zero and i had just thrown things at it as much as possible. No matter how hard i try, i am not able to make this happen. Did that ever happen again?

ju-sti commented 4 years ago

Thanks for trying. I "uploaded and started" at least 30 times since that error occurred but the error did not happen again.

I definitley cant reproduce it. Sorry.
