Hi
I copied my set of g-code files over to a Thinkpad.
There were a set of 20 g-code files of various sizes from a few KB to 33 MB
I had ONE failure , the same one I have been seeing on my workstation PC (Dell T7500). It happened at my first attempt to upload to the Duet from the ThinkPad.
After that, I had 19 successful uploads
So then I went back to the workstation and decided to copy the g-code file set from Hard Drive F onto Drive C, a solid state drive.
Using a Chrome browser, I was now able to upload the file set with no more errors, they were gone.
I then used Firefox which also had previously failed and again the files uploaded with no problem.
Finally, I went back to loading from Drive F and using both Chrome and Firefox I was successful in loading all the files without error.
The problem seems to have sorted itself out overnight. I did nothing to solve the problem other than what I have outlined above.
Magically, I can now use Chrome or Firefox to upload to the Duet, go figure. I hope it stays fixed.
