Is that it, a bad connection? Some days I fix those all day long. 
Nothing a bit of wire and solder can't fix. I forget how many layers 
these boards use, but there is always a component somewhere that you 
can tack a wire too. May not look pretty, but how often do you show 
off the inside of your printer? If it is the connector on the end of 
the cable, that might be a little tricky, but you don't always have 
to use the exact replacement connector, you can get any pair and just 
hang one part on the board with wires, and then install the mate on 
the cables to the motor.

You might be surprised how often really expensive equipment gets a QC 
fix by running a wire on the board to fix a bad trace, and make a 
modification/upgrade before they revise the actual board. I can't 
tell you how often I get something that cost $15000 or more that 
arrives with a small mod or fix to a PC board, broadcast TV cameras, 
routing switchers, tape machines. It's actually rare to get something 
that doesn't have some kind of repair or change, especially when you 
get into 6+ layer boards.
