Hi All,
I have a MakerFarm Prusa i3 that I wanted to decrease the bed heating times. (RAMPS 1.4) I bought a silicone heating pad and aluminum build plate from RepRapChampion

Installation was a no-brainer, but I kept getting "Bed Heating Failed - Printer Shut Down - Reset Printer" or something close to that. I purchased their Heated Bed Power Module

but I'm confused about how to wire it. I sent them an email asking for help, but got a generic "just think of it as an extension to your RAMPS" reply - which I found inadequate.
Can someone who has installed this module to a RAMPS board give me a more detailed wiring description?
I originally thought the D8 + and - went to the DC POWER In + and - on the Power Module, but then there is no place to connect the Control Input + and -.
I am beginning to think that the RAMPS D8 + and - go to the Control Input + and -, but it bothers me that the D8 is what originally supplied 12V high amperage to the original heat bed, so don't want to blow up the power module or my RAMPS.
Also, do both sets of 12V power still connect to the RAMPS and another 12V power to the power module?
Thanks for any help,
Gary
