Wiring a Solid State Relay to Ramps
I am thinking of replacing the relay on my Makerfarm i3v 10" with a solid state relay & adding one to my FolgerTech Delta, but wanted to know how to hook it up before ordering a couple. I found these 2 images. The 1st one I don't understand why having the heat bed + going to the SSR - would be a good idea. http://3dprintboard.com/showthread.p...large-heat-bed!!!
This 2nd one shows what makes more sense to me. http://www.soliforum.com/topic/9004/...-installation/
Do either of these look like the correct wiring? Think I also read on here that I need 12v wired to the 11amp connection on the ramps also.
Also does anyone have a recommendation of which relay to buy?
