Hi, my makerbot wont work!
It is basically stuck on the first page and keeps blinking because it is trying to build from SD. The M seems to be triggered and it keeps playing the SD card missing sound.
Now I tried many things.
1. I took off the touch pad and it continues to beep.
2. I swapped out my interface and it does the same
3. My interface does not beep on another machine.

4. A brand new interface still beeps on my machine
5. Id` swapped out the wire for the interface and still does the same.
All this leaves me is that the motherboard is messed up? Does anyone have any idea why it is doing this?

Did you try another sd card? I know some time the sd cards can get damaged an read as no card found in the printer

Have you tried reloading the firmware from makerbot

Yes I have, I uploaded the old firmware and it didnt work. So i uploaded the new firmware again and it still didnt work.

Sounds like you might need the mighty board then looks like you covered all the basics

I really hope thats not the issue. but thanks!

When I bought my replicator 2x it started doing the same thing after the 2nd print. Maker bot support try ed to send me a mighty board under warranty but I ended up sending the printer back before they sent the replacement. I wasn’t going to be stuck with a lemon haha. My point being is once I contacted them about the issue the first thing that they wanted to send me was a mighty board. So obviously they have had this problem before and have fixed it with a mighty board. You might need one unfortunately.

Yea I called them and I guess I have to get a new mightboard. Its 403 dollars. I dont understand how this even happened…

I have one that works but the USB does not recognize so you need to print from the card if you are interested in that email me tklass@gmail.com

Internal microprocessor short or something similar. Is the most likely cause. It can happen after dozens of heat expansion and contractions.

No way of fixing this short?

I don’t think it would be possible. So many tiny traces how would you even start looking for the short? It could also be a bad diod or transistor internal to an on board chip.

I had that same issue a few weeks after I received my Replicator 2x… luckily I was under warranty so I received a new mightyboard… that’s the issue… one thing I could think of suggesting to avoid that issue (microprocessor overheating) is to wire a fan perpendicular to the board to push away the heat (even though heat rises, because the chamber is enclosed, a lot of heat reaches the board)… I have already added a third fan to the double extruder… so wiring another fan isn’t too much of a deal…
