Hey everyone. I have a prusa i3 with Ramps 1.4 and cannot get it to power on without plugging the Arduino into a 5V USB power supply. I have both diodes (D1/D2) installed and I have a 12V 30A psu purchased from Amazon (http://www.amazon.com/Universal-Regulated-Switching-Computer-Project/dp/B00D7CWSCG/ref=sr_1_1?ie=UTF8&qid=1397876792&sr=8-1&keywords=12v+30a). I also have a reprapdiscount smart controller am able to print when not connected to my computer, but absolutely need to be connected to a 5V wall charger. I just replaced both diodes today and still having the same problem. Offline printing once worked but I feel like it may be that I added too many AUX electronics (auto level servo & LCD). Does anyone have any possible suggestions?
Thanks
Thanks
