Firmware Update fail
Hey guys, I'm trying to update the printer firmware to the latest 3.8.1 but while I'm checking the dialog box it keeps telling me it has failed as the "The semaphore timeout period has expired.". Now I have checked and made sure I'm on the correct COM Port and I have re-scanned for the printer multiple times, I have also changed to all of my different USB ports but I still get the same error. I'm just wondering if anyone else has come across this and found a fix.
Cheers
RE: Firmware Update fail
Did you switch on the printer?

I try to give answers to the best of my ability, but I am not a 3D printing pro by any means, and anything you do you do at your own risk. BTW: I have no food for…

Now that is just cruel...
But did you?

Maybe a corrupt hexfile, network driver problems, Firewall blocks, try after fresh system reboot. If nothing works try the flash, if available, with a linux system. Use latest PrusaSlicer Update (2.1.0).

@just3d
Lol, yes the printer is switched on

Don't feel picked on. We have had users that did not realize that was required.
RE: Firmware Update fail
Ok, I have now downloaded the latest Slicer 2.2.0 and restarted my computer but I still can't get it to flash through Slicer. Is there another program I could use to flash it with?
RE: Firmware Update fail
Didn't Prusa have another firmware flasher before they integrated it into Slicer?
RE: Firmware Update fail
Yes, but it doesn't handle the alternate languages

Ahh I see, thanks for that. I guess I'll just have to keep trying to figure out why all of a sudden it wont update the firmware.

Have you tried a different USB cable?

Hi Joan,
Yes I've tired a different USB cable, I have also tried different USB ports on the computer as well.
And Karl,
Yes Prusa Slicer recognises the COM port as COM3 and I have also checked this within Device Manager as well. As for the error message, it comes from the Firmware updater itself under the "Advanced Dialog" tab, I have attached a photo so you can see.

I wanted to flash to firmware 3.9.1 today and had the same problem/error. Bluetooth and WLAN deactivated and it worked! Thanks!

RE: Firmware Update fail
This solution also worked for me, but I was getting a different error message...I'm using a Macbook Pro, and was getting a firmware fail message, but the log file was blank. Tried a different cord, USB port, reinstalled PrusaSlicer, redownloaded firmware update...nothing. Then turned off bluetooth and restarted computer, and voila!
