I've finished soldering my RAMPS 1.4 board and now I'm trying to test everything is ok. I'm powering the 5A input with a 12V power supply and just trying with X-axis (with a jumper in the x-axis end-stop) and an stepper connected to the X-axis pololu.
My first surprise was that power led is not lit in RAMPS board when powered up. Next I realized it is connected to Arduino's pin 13. If I run Blink example then it flashes happily (I was not expecting this though).
Next I downloaded Sprinter from github, compile it specifying the Mega board I have (1280 instead of the more popular 2560). I'm using Arduino 022.
It seems like the pins are not correct for this combination.
Power led flashes every time I connect from RepSnapper. Manual controls cause nothing significant result (no stepper motion at all).
It seems like there is a mismatch in the output pins. But as this is my first RAMPS experience I am a bit lost.
Are the any suggestion I should try (before just writing my own test Arduino scripts).
Thanks a lot,
misan
