HEATBED HEATER REMAINS ON
I have constructed a new printer Ramps 1.4. and testing.
Now have now connected the heat-bed and hot end heaters.
When I power the printer on, the heatbed heater turns on.
There seems no control. I have connected Ponterface. I can`t have it shut even via the M code.
The diode connected with the heatbed heater is solid on and does not flicker. Is this a firmware issue or something to do with my ramps board?
