Hello,
I have a Ramps 1.4 board and I have flashed it with Marlin 1.1.8 in EFB config, and I experience multiple problems:
- The heatbed is always on, as soon as the power is turned on the heatbed will start up heating. The heatbed is connected to D8
- The fan is not spinning up when the power is turned on (not the fan connected to D9, but the one near the X axis stepper). The fan spins if I connect it directly to the 12v
I'm inexperienced with the Ramps board, so I don't know where to look/how to debug further. It could also be that the board is damaged somehow, but I want to make sure that the FW is configured properly and the connections are OK before ordering a new one
