Hi all, first time poster long time lurker...
So I'm building a machine using a mini Rambo and am running into a problem I really don't understand. When I send the Gcode to turn on the nozzle heater, it turns on the nozzle heater. But when I send the code to turn on the bed heater it...turns on the nozzle heater. There is power supplied to the bed IN and main power IN, but nothing to the bed OUT, only to the extruder OUT (checked with multimeter at the screw terminals and the solder blobs on the back side of the board). It's a brand new board, my fuses seem fine, nothing is melted or shorted that I can tell. The thermistor is being read properly. I've tried controlling the board using both Printrun/Pronterface and Cura and I see the same problem with both. Anyone run into this before?
Here's my equipment:
-mini Rambo running Marlin 1.1.5
-24V power supply
-heater cable for the bed
