It’s official, it’s annoying Monday. My a250 out of the blue started to not feed the filament. This is with a machine that has only had two reels of filament run through it and a new hot end. So, no worries I have a new print head and I will swap it out. Turn the machine on a Snapmakers is whining about obsolete firmware in the tool head. No worries I’ll update via USB and I go to files and USB is grayed out. Okay burn another USB stick with the firmware and achieve the same result. So Snapmaker now what? Can I reset the printer to default and then get it to download and update the firmware via Internet the machine and tool head? How? Also, what do I do about the apparently dead USB? Annoying spending more time tuning, fiddling, repairing than I do printing with a newish machine.
If you plug the USB stick(s) into a computer, what happens? Did your computer ever suggest that you “repair” or reformat the USB sticks? The Snapmaker is very specific about what file system it expects to find on USB keys.
The supplied with Snapmaker USB stick is being used. It did whine when inserted into win10. I did the recommended fix – did eject. No change whe inserted into SM. I took another USB drive and formatted it (FAT32), copied the firmware to it and it does nothing either with SM. The female usb port in the SM hub is lite up when booting.
I did decide to go ahead with running a test print with the new print head (with the obsolete firmware – I have but am not running the 4th axis) that I BOUGHT AS A SPARE and after calibration nailed a perfect print. So in my opinion the original print head supplied with the SM, even with a new hotend is in trouble.
So we now have three issues, a print head problem, a usb problem and a firmware problem

Don’t do this. This will make changes to the file system on the stick causing the snapmaker not detecting it anymore.
Martin as mentioned it made no difference before fix or after… further it is formated FAT32.
If you’re absolutely sure that your USB sticks are correctly formatted, it may be time to talk to support. They should be able to help you troubleshoot further and see if you have a bad USB port on your A250.
