Is my RAMBo card finally giving up?
Posted: Thu Feb 21, 2019 1:09 am
Hi all
I have an M2, I've had it for six years now..
For most of the last couple of years, I've printed happily with octopi sending all files to my M2, everything have been working great.... Up until one point!
Now, I have failed prints at random, for no apparent reason.
Well, I know the reason. Octopi claims the serial connection went down.
I've looked in to this, and this could potentially happen if the raspberry pi had substandard power supply. Mine does not. I use the official rpi power supply. Besides, this was working fine with nothing changed for years.
Fast forward to now. I am lucky to get a print through without my M2 stopping mid print... waiting until the timeout happens, the bed drops and then it just sits there. hot end and bed still on, fan going full, but nothing else.
So, I have changed out everything. I have changed power supply, ssd card, rpi and cables. I've even replaced all cables in my M2 in one go.
Today, I did however do one thing. I took the case off, and when my M2 failed mid print, I noticed that I had two LED's on the RAMBo not acting as they should.
LED2 was blinking red, rapidly, and LED3 was shining with a steadfast red light.
So, my Google-Fu has not led me to any answers what these diagnostic lights actually mean, but blinking red is rarely a good sign.
So I ask you: Does anyone of you know? Since the printer is sort of working, I don't think it's a fuse. All fans and heat bed and hot end is working. It just fails randomly. More often than not, actually. Especially on long prints.
I thought it could be over heating, but I see no such thing to support this.
Please help: Is my RAMBo starting to die on me?
best,
Micke
