Can’t upgrade firmware beyond 3.9.3 using Macbook  

RE: Can’t upgrade firmware beyond 3.9.3 using Macbook

If you can flash firmware with your setup then it will be nothing to do with your laptop. It will be the einsy board I think. I seem to vaguely recall there were issues around some boards, check the mk3 firmware GitHub issues both open and closed. 

RE:

This error did happen with the 3.9.3 firmware maybe something in common.        https://github.com/prusa3d/Prusa-Firmware/issues/2954

RE: Can’t upgrade firmware beyond 3.9.3 using Macbook

Just to be clear, the newer firmware will flash and the progress bar in Prusa Slicer says complete and no problems but when the printer reboots it won’t advance past the Welcome screen.

are you pressing the LCD Knob, or the X Button beneath it?  

the X button is a reset.

and you are defintly downloading mk3s+ firmware not mk3s any chance you can take video of you downloading firmware and it booting up all in one video

thanks

RE: Can’t upgrade firmware beyond 3.9.3 using Macbook

From what I can gather on GitHub it’s the data in the eeprom that doesn’t get updated correctly and so it doesn’t work when flashed and can’t proceed.  

RE: Can’t upgrade firmware beyond 3.9.3 using Macbook

Pushing all the buttons at one time or another. I can reload 3.9.3 and everything works fine, can print, just can’t update beyond that. Every time I go to print the LCD says I should update, but will disappear as the print begins.

More info for what it’s worth. Purchased the Mk3 in 2018, upgraded to the Mk3S in 2019. Do not have the Mk3S+. As I look at the firmware downloads, there’s a difference in that the more recent firmwares include Mk3S and Mk3S+.Not sure if that’s part of the problem. When done with printing I’ll take a video. 

RE: Can’t upgrade firmware beyond 3.9.3 using Macbook

try downloading mk3 firmware not the mk3s

RE: Can’t upgrade firmware beyond 3.9.3 using Macbook

the firmware i downloaded for mk3s name is prusa3d_fw_MK3S_MK3S+_3_11_0_4955.hex

RE: Can’t upgrade firmware beyond 3.9.3 using Macbook

That's a pretty old MacBook using an old OS. The OS is now up to 13.1. You might try upgrading the OS to the latest 13.1.

Jus a thought.

RE: Can’t upgrade firmware beyond 3.9.3 using Macbook

Thanks for all the suggestions. As to the MacBook, it loads the 3.9.3 fine. The last compatible OS is 11.7 for this MacBook. 

I think I’ve tried all the permutations. I’ve flashed Mk3 ( not S) for 3.10.1 and 3.11 with the same results as with the hex for Mk3S/Mk3S+( nothing progresses past the Prusa Welcome Screen) , but can flash 3.93 without any trouble, and can print just fine. It may be the einsy board as suggested. When I reviewed the GitHub link the problems are very different than what I’m seeing on the LCD screen which looks normal but doesn’t progress. 

I’ve also compared  the logs from the flash of 3.9.3 and 3.10.1 and they look the same except for the version being flashed and the number or bytes transferred. 

Maybe I should just accept that I can print successfully. The alternative would be to replace the Einsy card.

Sorry, couldn’t upload the photos I wanted but you’d be bored looking at them.

RE:

press the button on top of the einsy next to the place you plug lead in to update then do a factory reset

RE: Can’t upgrade firmware beyond 3.9.3 using Macbook

I’ll give that a try. Thanks!

RE: Can’t upgrade firmware beyond 3.9.3 using Macbook

I caRnt rember if it's press or hold for a few seconds try both and do it in new firmware and old firmware 

RE: Can’t upgrade firmware beyond 3.9.3 using Macbook

Hello, Hello. I gave the reset a try. Afterwards I could see the status screen after flashing 10.1 ( which had not happened before) but could not advance beyond that. Re-flashed with 9.3.1 and everything works. Were you saying press the reset button on top of the Einsy and THEN do a factory reset?  Not sure of the purpose of the reset button vs the factory reset using the control panel. 

I do appreciate all the help so far. 

RE: Can’t upgrade firmware beyond 3.9.3 using Macbook

yes i know it sounds bazare but pres the button on the einsy then do a factory reset it may work but no promises or factory reset then press button on einsy button on the einsy resets board and factory reset only clears memory

RE: Can’t upgrade firmware beyond 3.9.3 using Macbook

Gave that a try, I think. Held the Einsy button down and restarted but it seemed no different than pressing the “X” reset button on the console. I did do a factory reset afterwards and got no further but thankfully can still print using 3.9.3. It’s aggravating to see the “Upgrade to 10.1” message every time I print but for nowI can still print without the firmware update. For what it’s worth I’m upgrading to Mk3S+, though I can’t see how that will make any difference. I’m resistant to replacing the Eisnsy board.
