I just bought a new RAMPS 1.6 shield to replace my old RAMPS 1.4 shield. The problem is that it's just not working, the motors don't move, heatbed/nozzle don't get heated. It was all working with the RAMPS 1.4 shield.

I checked the RAMPS 1.6 and there's no bridging in the solder joints.

The DRV8255 is drawing current also but the motor doesn't move.

I am using Repetier Firmware. I tried Marlin (default) and even it's not working.

Pins are sometimes different between the two shields. I ran into one a while back... Go over the pin specs for the 1.6 one at a time.

Correction: pins are SUPPOSED to be the same. I've however experienced them not being the same. I don't know if my 1.3s were the oddballs or if the 1.6 was.

So In my case, the RAMPS were defective, I returned them and got a new replacement from Amazon. The new one worked just fine.
