Having trouble updating to the latest firmware.
I'm trying to update my mk3s with prusaslicer runinng on windows 10, but it keeps timing out on the com port connection:

avrdude-slic3r done. Thank you.
=======================================================
So I'm on firmware 3.7.2 at the moment. I updated it from 3.7.1 using prusaslicer the same way I'm doing now.
I can print with pronterface on the same com port. I can print with octopi. When I tried to update with the firmware updater plugin for octoprint , it also timed out.
I've only been using the printer for a couple of months so I'm still kinda new at it all. Does anyone have any idea what could be the cause of this?
RE: Having trouble updating to the latest firmware.
I got it working after following suggestions on this discussion:
https://stackoverflow.com/questions/19645441/avrdude-stk500v2-receivemessage-timeout
Basically I clicked on the flash button in Prusaslicer immidately after I pressed reset button on the printer. I have no idea why this works but if you have the same problem, give this a try.
After flashing and the printer reboots, Prusaslicer will complaine that it lost connection with COM port, but this is ok. Firmware has already been flashed.

This tip just ended a morning of frustration for me. Thanks! Surprised this is still an issue after so many years.
My printer has been sitting for a few months, and I was worried it had died of loneliness or something. 😛

Wow! Thank you so much! This fixed my issue when upgrading my MK3 to an MK3S+!
RE: Having trouble updating to the latest firmware.
That, Plus Switching my Port on the PC a few times got it working.
Before it shutted down after aprox. 44%.
Tank you!
