<p>I switched my Anet A8 over to a Bowden and it's printing great. Moving that weight off has enabled me to almost double the speed and resonance problems have vanished. </p>

<p>My question is regarding after the print is done should I add a retraction code and back the filament out of the v6 or is it okay to leave it in there?</p>

<p>My concern is that if I leave it in there, will it cause a clog or anything when I warm up the printer tomorrow to print something else? If that's not a something I should be concerned about let me know.</p>

It's okay to leave the filament in the hot end, as long as you let it cool down with the hot end cooling fan running.
From comment:
That's not an issue, you can simply leave it in the hot end. The only "end of print" clogs usually occur when leaving the hot end hot for a while - allowing the filament to drip out - and then retract the filament without feeding it against the nozzle once more. That creates a plug that's larger than the filament diameter that might get stuck in the bowden tube
