Hi! No problem..I appreciate your response. Cheers

Hi all,
Since my last post didn't receive any replies and all my trial and error to locate the source of the problem drew a blank, i am considering replacing the electronics of my BFB 3000 DUAL extruder.
Is there anyone who has successfully done this? If so, is it possible to guide me in a step by step detailed format so I can carry out this conversion?
I have recieved a lot of help from the openbfb google group, and have done a little research about marlin firmware and some electronic replacements. But nothing for sure.
I am skeptical about starting with this conversion due to my incompetence in this field. I will be consulting someone who has knowledge of electronics in 3d printing while I take this path.

Thanks and regards.

Hi! Thank you for replying. Else i have been just staring at all the forums
The thing is, the printer has been working flawlessly for the past 6 years.
I have even checked the installed firmware hex files and the comparisons show that all of these have been loaded successfully.
Inference : the board is receiving the firmware.
But it just doesnt get out of the bootloader mode.
I even opened up the control unit, cleaned the board, checked for sticky buttons.. But nothing! I feel sad.

Hi, I have an old BFB3000 dual extruder. Its old but was working exceptionally well until a short while. I hadn't used it for over 7months so it was just covered. Now when I started it, it is continuously stuck on bootloader mode. I tried switching on off quite a few time, updated the firmware to 4.1.1 via usb. Everything seems fine. Except the screen keeps showing bootloader v 3 all the time. Any help?
Oh yes... It did start up for only once for a short while and when i restarted the printer, it went into the same loop. Please help ifanyone knows whats going on. Thanks.
