Working on installing my Bulldog Lite and have a few questions.

Are you using the PTFE tube? I have seen it both ways, not to hard to try it both ways as well just curious about users experience either way.

Where are you connecting the fan to your RAMPS, RUMBA or RAMBO? Just using the normal 12V out (D9 on RAMPS) so that it is on all the time? Also was the fan sufficent in keeping the cool end of the hot end cool for PLA?

Have you tried fitting another fan to cool the print or is the downward draft from the extruder fan enough?
