What happened?

This warning indicates that the printer is experiencing slow G-code data transfer, either from a USB drive or over the network. The message shown is: G-Code transfer running too slow. Check your network for issues or use different USB drive. Press Continue to resume printing.

This can occur if the USB drive is too slow or corrupted, or if the network connection is unstable or under heavy load. 

Thanks to G-Code streaming, the printer can start a print, even if the entire file hasn't yet been fully transferred to the USB drive.

How to fix it?

Check for:

  • Stable Wi-Fi or Ethernet connection to the printer
  • Low network congestion or interference
  • Avoid using slow or heavily fragmented USB drives.
  • After checking or replacing the source, press Continue on the printer to resume printing.

If the issue persists, transfer the G-code to the USB drive before printing, or use a different USB drive to rule out hardware or connectivity problems.

I figured out how to make it work. If you open up Connect and cancel the transfer of the printing file and go to your connect files, and select the exact fie you were printing and click print it should give you the option to just transfer the file to the printer. once the file is transferred you should be able to resume the print. This worked for me a few times.

Man you're a legend. Worked flawlessly, and saved my print that was at 94% after 3+ hours.
It was scary to cancel the transfer, but I thought nothing to loose, and when the new transfer caught up with the existing one the print auto resumed

Thanks again for this hack!

The information from your comment needs to be added to the main article content, it is print saving knowledge.

I was also initially concerned about trouble shooting the USB while the print was paused. But knowing that the transfer could be cancelled completely and reinitiated helped.

This allows you to remove the drive and clean it with your computer, even directly transfer it from here rather than the cloud, then reinstall it and resume the print.

Saved a print that paused 10 hours into a 12 hour print.

You are indeed a legend. My 22 hour of print stopped in last 3 hours because of it and I was able to continue in this way.

Both printer and Computer lost connection to Prusa Connect, while local network, WiFi, and Internet connection run smooth.
How to continue the ongoing print job (read re-establish the Prusa Connect connection?

I've wondered the same....had 2 prints fail like that in a row. Just decided to put the file on the USB key, we'll see if that works.
