Turing Machine Pulses

Hi,

my Pulses Expander for Music Thing Turing Machine never blinks at 4+7 and 1+2/4+7 Outputs.
No Gates are being output either.

Is it broken or am I missing something?

Thanks for answers!

Does this happen even when you set all bits to 'On'? If so then yes, there could be an issue with the expander.

I'm not sure what the results of connecting the expanders to the wrong headers would be but perhaps double check that the ribbon cable is connected to the correct expansion header and that it's oriented in the proper position.
