Afternoon all,
I'm new to all this stuff so try not to hit me too hard with the technical stuff, but here's the problem. I have a sintron printer which I beleive is just another prusa i3 copy/whatever, and I've got it set up pretty well, it does every thing I need it to and gives fairly consistant results. My problem lies with the ardiuno board has to have a constant connection with the laptop to work, I have a LCD2004 setup with this printer so it has the SD card slot in the back allowing this to do its thing off line. Except it can't.
I've got the multimeter out and checked the connection I thought would matter, and I'm getting a solid 12.09volts from the PSU to the ramps board on all four wires, now while searching the internets for answers I came across a few people saying about D1 and D2 diodes, and it looks like D1 has a lot to answer for, so I checked it with the multi meter and across the diode while just plugged into the psu it only registered 0.68volts but wth the usb only there was 3.99volts across it.
So at this point I'm confused and don't know what to do or try, can someone help?
