Welcome to the SeeMeCNC Community

Greetings all!

I had a RAMBO card go out - I was cleaning the hot end tip with a brass brush and accidentally hit the LEDs. I got a spark, and the RAMBO blew a fuse (even though the LEDs don't go through the RAMBO - just uses the same power supply). I replaced the fuse, and when I turned it on, the card booted, homed the towers (never homed before), then displayed "RE-SETTING E-STOP" and immediately re-booted and repeated over and over.

I sent the card to Ultimachine for repair. It came back, and when I loaded the Repitier firmware, it stated doing the same thing as before.

I'm not sure where to go from here. Help!

Does it do the same thing with the LCD disconnected?
The only EStop I'm aware of is on the LCD controller.

Other than that I think you'll have to talk to ultimachine.

I'll check that. I have the same hardware running on another RAMBO board right now.

Did you load a new version of repetier, or are you using the same version as before?

I am on the current version. I was on the current version when I started using this card.

I will probably install the card this weekend and try it without the display attached. I currently have another card in there, and it's working with the display, so I am not hopeful.

I tried playing with the firmware using just the USB plug, but the 1.2 cards don't have that jumper, so you must have 12v to the card in order to do this.
