Graber i3 PSU Holder http://reprappr.blogspot.com.br/2014/07/graber-i3-ps-on-com-fonte-industrial.html My Graberhttp://www.thingiverse.com/thing:182675 Graber i3 - PS-ON with industrial source In my Graber i3 operation of the power is controlled by Ramps 1.4, through pin PS-ON. How to call "industrial" source does not have the same start one pin ATX power supply, it was necessary to adapt a relay to serve that purpose. This here is the case I made to house all the electronics. I had to draw another one, because my source has only one hand to hold the screws. This blue color was the first version, I remade the impression and changed all parts by brown, similar to the color of the MDF, but how does not matter, this picture will serve. I will not pass the file of this case, because it is very specific, and do not advise anyone to buy fountain with screws one side only, as I did. Instructions Normal operation (without PC): Turn the power switch Press "start" (pressure switch) - you may need to hold for 1 second or longer to start, but it is usually pretty fast The power supply is energized, and consequently also the Ramps Ramps the relay remains active through the power of PS_ON Running through the USB (PC): Turn the power switch Connect the Ramps (Arduino) USB on PC The power supply is energized, and consequently also the Ramps Ramps the relay remains active through the power of PS_ON Normally this configuration Ramps already correct, but if it does not work, you must configure the firmware, as an example, in Repetier firmware (Firmware-https://github.com/repetier/Repetier), the file "Configuration.h": -> #define ENABLE_POWER_ON_STARTUP // may not be reviewed, but does not start -> #define POWER_INVERTING 0 // reverse to "1" if the relay does not work To turn off the printer at the end of printing, Slic3r (http://slic3r.org), configure script final printing, putting the "M81; ATX Power Off" command:
