Printer will not boot

After finishing a print earlier i was prepping for another and when i started the new print i got a bed preheat error. It has happened to me in the past and a Firmware upgrade fixed it. So i went looking to see if a new firmware was available and saw 3.8 is out. So i downloaded it for my 2.5 opened Prusa Slicer and Flashed the firmware. Literally just as it said it finished the screen went to 2 solid bars and a loud and very continuous beep started emitting from the printer. Only choice i had was to power it off by the switch. 

Turned it back on and still the same thing 2 bars and never ending beep. Tried re-flashing the 3.7 FW but to no avail. got me one loud dead printer. Anyone have any thoughts on this one. i did a search on the forums found nothing specific to what i am experiencing.

I had the same issue. Until I realised that I had picked the wrong HEX file. The one I picked was for the rambo 1.0a instead of the 1.3a that is in my printer. That was my problem. Have you checked you chose the right HEX file?

Yeah that was what I found. I wish they would just split the hex files into separate folders in the update just to make it easier.

Yep, I agree! So you're up-and-running again? Happy printing! 😉
