I am upgrading my self made Prusa i2 from ramps 1.4 to the UltiMachines Mini-Rambo 1.3. However I am experiencing some issues connecting to the board to Arduino IDE. The following mistake pops up:
Thank you very much, it resolved the problem. However I can not connect to my Mini-Rambo. When I first tried it out I mixed the cables and connected the power supply to the output of the board. I checked the fuses and I did not blow any of them. Is there something that I am missing. Why I can not reach the board ?
I added a second power supply on the input B and that was the issue. I had wired it wrong. It works now all LEDs blink, I connected to the board from PRONTERFACE and uploaded from Arduino IDE. Now the warnings in the code and connecting all the motors sensors are left.
