Hi,
I just switched from Sanguinololu to a RAMPS and everything appears to work great.
The only issue is my heated bed output. I have a custom heatpad which draws more amps than the normal MK2 heated beds and therefore I had the power to the bed going through a relay and the relay itself was switched on by the power terminal for the heated bed.
So I just tried to replicate the setting on the RAMPS. I have a separate PSU on the 5amp input and the 11amp is empty at the moment. When I now give the command to power up the heated bed I dont hear the relay switching on.
So my question is if the heatbed output only comes online when its powered by the 11amp input and if there is a way to get the board working on only 1 PSU (I saw a post somewhere with a similar "1 PSU for the whole board" but cant find it anymore)
