I am having an issue with a new Rambo board I bought from the V1 shop. Among plugging it in I realized that everything was working but I could not control the motors. After successfully reflashing firmware I tried again, no luck. I already have a Rambo that I use with my 3D printer and I thought I would try it, so I flashed the firmware to it and bang everything worked and I successfully drew the infamous “crown”. This morning when I thought I’d give the new board another shot, I realized it would not power up. I feel like it cannot be defective since Ryan tests everything first, did I somehow short the board? I’ve barely touched it, especially when it’s been plugged into power. Attached is a video of me powering the old Rambo and then moving it to the new one (no power LED) and a close-up picture of the board to show no disturbed components. Hopefully, I didn’t waste $150. Thanks for your help and time!

First step I would check all three fuses.

I will switch the 5A fuses on the two boards and try again! Sadly I left for school so I will need a day or two to relay this back home.March 25, 2019 at 11:44 am #94506
My board no longer works but it’s because I made a very stupid mistake and hooked up the 12v power backwards. Now when I plug the USB into the computer, the computer reboots.
Is there any chance that there’s a simple component replacement? I checked the fuses and they’re good.
I’m currently using an Arduino Mega and RAMPS combo. Is the RAMBO preferred?March 25, 2019 at 12:31 pm #94511
John the ramps does not have reverse current protection, your board is dead.March 25, 2019 at 6:05 pm #94561
