Cannot upload firmware on Rambo Mini 1.3
Hi guys,
Just finished assembling my mk2. Wow, what a difference in quality from the cheap aliexpress printer I got earlier this year. Everything went together without a hitch, but I'm having problems updating the firmware. It's a brand new Rambo Mini 1.3. It connect to win 10 machine fine with the downloaded drivers and shows up con com 9. The Green power status light is on, and when I use the update firmware utility, it prompts me to not unplugged, and the board flashes an amber light about ever 15 seconds. I've waited for hours, and nothing.
I also tried to use arduino 1.06 to upload the firmware manually, but I get an axis out of scope error when compiling the lastest firmware of git hub.
Any help would be appreciated.
Thanks!

USB isn't enough to power up the Rambo Mini. You also need to give it 12 volts or it does not upload. It can connect but it won't upload. I lost a day messing with it till I figured it out.
