Prusa Connect transfers - created folder instead of file  

RE: Prusa Connect transfers - created folder instead of file

Hello,

This is definitely not the intended behavior, as the printer needs a .gcode file to execute the printing instructions.

Here's a breakdown of why this might be happening and what you can try to resolve it:

Possible Causes:

Software Glitch in Prusa Connect: There might be a bug in the way Prusa Connect handles file transfers to the USB drive specifically for the MK4S in certain scenarios.USB Drive Compatibility Issue: While less likely since direct PC uploads work, there could be a subtle incompatibility between the USB drive and how Prusa Connect interacts with it.Corrupted Prusa Connect Configuration: Your local Prusa Connect configuration might have gotten into a state that's causing this incorrect file creation.Firmware Issue (Less Likely): Although you mentioned it works via direct USB upload, a specific interaction between the firmware and Prusa Connect during USB transfer could theoretically be a factor.Filename Issues (Less Likely Given Folder Creation): While long or special characters in filenames can cause transfer issues, the creation of a folder with the filename is a different symptom. However, it's still worth keeping filenames simple for testing.Troubleshooting Steps:

Restart Everything:

Restart your Prusa MK4S printer.Log out and back into your Prusa Connect account.Restart the device (computer, phone, etc.) you are using to access Prusa Connect.Try a Different USB Drive: Even though your current drive works with direct uploads, try a different USB drive (preferably a known good quality USB 2.0 drive, formatted to FAT32) to see if the issue persists. Some users have reported better compatibility with certain drives.

Format the USB Drive: Ensure your USB drive is formatted correctly as FAT32. You can reformat it using your computer's disk management tools or a dedicated formatting tool like Rufus (as mentioned in some online discussions for similar Prusa USB issues). Make sure to back up any important files on the drive before formatting.

Simplify Filenames: While it might not be the root cause of the folder creation, try using very simple filenames (e.g., test.gcode) for your uploads through Prusa Connect to rule out any unexpected filename handling issues.

Check Prusa Connect Version: Ensure you are using the latest version of Prusa Connect. Prusa might have released updates that address bugs related to file transfers.

Re-Pair/Re-Add Printer to Prusa Connect: Remove your MK4S from your Prusa Connect account and then re-add it. This can sometimes resolve configuration glitches.

Check Prusa Firmware Version: Ensure your MK4S printer has the latest firmware installed. While direct USB works, a firmware update might address potential communication issues with Prusa Connect.

Try PrusaLink (If Applicable): If you have PrusaLink set up (the local network connection), try sending the G-code file through PrusaLink to see if that works correctly. This can help isolate whether the issue is specifically with the Prusa Connect to USB transfer process.
