I am trying to get my heated bed working with Ramps 1.4 & Marlin. Bed came from Sainsmart and is the 12/24v version hooked to D8. I have a big power supply set to 12v on both power in points. Thermistor is reading room temp connected to T1. LC display shows B020/060. So it is showing temp should be at 60. However, I get zero voltage out of D8.
This is a new printer and the heated bed has never been hooked up. I think the mechanics are hooked up correctly.
Marlin:
#define PIDTEMPBED
#define BED_LIMIT_SWITCHING
#define MAX_BED_POWER 255
I don't know where to go from here. Help please.
