Check that the I_5V_EN jumper is still in place, disconnect everything from the Duet except VIN power, and make sure that it isn't sitting on a conductive surface. If you still get only the blue LED lit up, please ask for your Duet to be replaced under warranty.

@phaedrux yup that was it - might be helpful just to drop a note on the instructions that this is normal

Awesome thanks! Fans are 24v; I'm hoping noctua comes out with some smaller ones by the time I'm ready to replace them with something quieter. Yeah, I'm just trying to minimize the amount of parts I'll find out are critical to having a functioning printer.
