Topic: Ramps Heater Wiring

I recently upgraded to a RAMPS 1.4 controller and all seemed to have gone well.  I can control everything fine except for the heaters.  I originally thought it was a bad wire connection, but then realized that I could heat the extruder by increasing the fan power.  I have the extruder plugged in to D9 and the bed into D8.  I can't get the bed to heat through the bed controls, extruder controls, or fan controls.  Any ideas what might be going on?

I'm running the firmware from here: https://github.com/mlaws/solidoodle2-marlin
My heated bed is the stock Solidoodle one and I've upgraded to an E3D v5 for the extruder.

Thanks in advance for any suggestions!

Re: Ramps Heater Wiring

There are two input power headers for 12VDC. One is the supply for the Heater output, and the other supplies power to everything else.

Re: Ramps Heater Wiring

Well then.  Problem solved!  I read somewhere that the other one was for a 24 volt psu.  I must have been wrong.  Thanks!
