Hi, I feel like a right idiot, it was a hardware issue after all! The top of the fan mosfet was leaning over and touching the heatbed mosfett, I have leant it back and everything is fine, thanks for all the reply!by flobbernoggin - RAMPS Electronics
Ramps 1.4 and Marlin - D8 and D9 Linked - 4 years ago
Hello, Have a bit of an issue with my ramps setup after updating firmware. If I turn my cooling fan on (via D9) or turn my heated bed on (D8) the other pin will also turn on. Its almost as if they are linked. I have check and I am using the EFB motherboard config in marlin, pins.h is referring to the right board, and in the ramps.h the D8 refers to 8, D9 to 9. The FAN_pin also points to D9 andby flobbernoggin - RAMPS Electronics
