Can someone please write here, what is the best power supply for RAMPS? I have RAMPS 1.4 and with my DC 12V 5.4A connected, steppers just don't move and they dont even make this noise everyone is writing about, when low voltage setting in set on pololu drivers. I have tried increase that, but nothing happend. Thank for response.by lukasso - RAMPS Electronics
Thank you, Ill try it again, but I have already tried this combination, and those stepper didn't make anything, not even that noise others are describing. Maybe i should also say, when I'm trying this, i have connected both USB and charger, which is 12V, 5,42A. Is that right?by lukasso - RAMPS Electronics
Thank you for your response, I have tried that for first time, because i sounded logical. Now i have tried combination, which is written on my ramps board (2b 2A 1a 1b) and i also doesnt work. Any other idea?by lukasso - RAMPS Electronics
