I'm seriously considering changing my Portabee (a Printrbot variant) with a direct-drive extruder, into a Bowden setup.
It looks like the simplest way of doing this is simply to unmount the motor from the X-carriage, leaving only the hot-end on the X-carriage.
The question, then, is if and how to secure the unmounted motor. I saw one Printrbot conversion to a Bowden setup here: [

As you can see, the drive motor and drive mechanism for the filament appear to be completely unsecured, simply being laid in some location on the table.
Is this an acceptably-stable arrangement for a Bowden setup?
