<p>Hi R,</p><p>You can use this hack with the RAMPS1.4 electronics. The idea behind the relay is that the second power supply unit doesn't influence the rest of the electronics. You don't have to worry about frying the RAMPS as long as you solder all the wires correctly.<br></p><p>If your output signal is 12V instead of 19V, then you have to change some resistors:</p><p>Use 1.2k resistors for R1 and R2 (mouser part# 660-MF1/4DCT52R1201F) to account for the lower input voltage.</p><p>/edit:<br>Updated my description, please read the new important notices in the bottom part!</p>

<p>You're welcome ;)</p><p>Right, the wiring... That part kinda got lost... somewhere.... o.O</p><p>I'll see if I can make something up during the week. Very busy these days.</p>

<p>Hi, just open Nick's model in Cura, right click on it and select "split object into parts". Then wait a bit (this may take some time and Cura will appear to crash) and you'll get the separate pieces. Then just right click on all the other parts and delete them one after another.</p>

<p>Hi kwatts,</p><p>Did you take exactly the parts I specified? Did you solder everything together as described? If you want to, you can make some pictures and send them to me. I sent you a PM with my E-mail address. I'm sure we'll find that error ;)</p>

Suggestion for holding the O-ring: T-slot (See comments section)

WOW! You are a genius Skip! I am so going to print this design :) About the O-Ring: You could make a T-Slot (I added an example picture). This would make it easy to replace broken rings, and if fitting properly, should not come apart by itself.

I was asked about alternative parts for the protection diodes: P6KE27A works as well. It's a bit smaller, but has almost the same specifications.
