Gcode files not showing up on USB or in local files when sent through wifi

Snapmaker 2.0
1

I updated My A350 with the latest version (4.10.2) and firmware but when i send files via wifi i get the “File Transferred!” screen on my. I click “Got it” but the files aren’t on the local drive. exported it to a USB and still don’t show up. all other files on the USB show up, just not the g-code. when i plug it back into the computer the g-code is there. I’ve uninstalled, turned off, turned on, reinstalled, turn off, turn on a few times to no avail. tried resetting the touch screen… still nothing. Any insight would be greatly appreciated.

Sounds like the file name isn’t recognised. Which software is producing the Gcode file?

To add to this: All the files are GCode, i.e. text files containing GCode commands in clear text, so the file type ending can be changed without the need to regenerate the file. Depending on which workload you’re using, the file ending sould be (with a grain of salt, just from memory - I may get things mixed up here, please correct me if someone knows better):

  • 3D print: *.gcode
  • CNC milling: *.cnc
  • Laser: *.nc

So, just rename your file accordingly, and you’re ready to go.

EDIT: Btw., if Snapmaker happens to read this: The file manager on the touchscreen could do with a considerable overhaul, like a) a tick mark that allows to show all files instead of the filtered view, b) a way to mass-delete files without the need to tick each and every file and/or c) a way to acces the files on the touchscreen via Luban or file explorer from the PC for a more comfortable content management.

We’ll have to wait and see which software he is using and which file name suffix it’s using to ascertain if that is indeed the problem.
It could be that the file is correctly named but the tool head fitted is causing the file name to be filtered out, and therefore the wrong file type is being sent for the current tool head.

I agree the touch screen interface needs an overhaul; some of the text is far too small, it doesn’t even remember your chosen sort order, the file time display doesn’t make sense (09:45 for 9:45pm!), heated bed option and number of points for levelling should be in the levelling menu not the settings, etc…

Still having the same issue. Using Luban, I can’t load filament or heat up the hot end. There’s a yellow clock icon next to my A350 in Luban. I’ve tried updating everything, resetting to factory settings, and troubleshooting, but nothing has worked. It’s incredibly frustrating—any suggestions would be greatly appreciated!

about files missing.

like @Hauke said you will only see files that are appropriate for the installed head. so extension names are important.

the other thing that used to get me is the file display. its not really sorted in any order. as the memory fills up files are placed where they fit. to see the “latest” files that were sent use the hamburger in the upper right to sort by date and you will see your latest file (ignore workspace entry)

SOLVED

TLDR: Toolhead port on controller was at least partially fried, mapped toolhead to add-on 1 port and everything works great again.

:magnifying_glass_tilted_left: Issues I Ran Into:

  1. My 3DP toolhead wouldn’t heat up — temp stayed at 0°C, no error message.
  2. Ran M1005 — no toolhead was detected.
  3. Tried a second (brand new) 3DP module — still not recognized.
  4. Plugged in the CNC head, and it was detected immediately and even triggered a module firmware update.
  5. Used the M1029 command to remap the toolhead to Addon-1, which allowed the 3DP module to be detected and heat up properly.
  6. But then — during actual prints — the extruder gear didn’t move and no filament came out (even though it primed at the start).
  7. After rebooting, the issue came back again.

:wrench: Fix Summary:

:white_check_mark: Step 1: Remap to Addon-1 Port

Since the default toolhead port didn’t work:

M1029 E2   ; sets Addon-1 as the toolhead port
M500       ; saves it to EEPROM (this is critical!)

:right_arrow: Plugged the toolhead into the Addon-1 port — it was detected and could heat up.

Important: If you don’t run M500, the remap resets on power-off, and nothing will work again after rebooting.

:white_check_mark: Step 2: Fix Extruder Motor Not Moving

Even with the toolhead working:

  • The extruder motor wouldn’t turn during the print.
  • Turns out this was caused by either:
    • The nozzle not being preheated
    • A Z-offset that was too low, choking the nozzle
    • Or a cold pull needed to remove partial clogs

Fixes:

  • Preheated the nozzle to 210°C before trying to extrude
  • Recalibrated Z-offset to avoid nozzle-to-bed contact
  • Did a cold pull to make sure nothing was blocking the nozzle
  • After saving the port remap with M500, everything worked and I completed a full PLA print

:light_bulb: Takeaways:

  • If your toolhead isn’t detected, try remapping it to Addon-1 with M1029 E2
  • Always run M500 to save that port change!
  • The extruder won’t work unless the nozzle is hot and the Z-offset is right
  • Cold pulls are your friend for partial clogs

Happy to answer questions if anyone else is stuck with similar issues. Hope this helps!
