Startup Routine, printer wipe etc

[dunginhawk]

Good evening... So ive got my ABL all set up and working, and very happy with it.
Next part is to find a good cooling system for PLA. last one i tried made the prints horrible on 3 sides, removing it fixed the issue, but i know i want cooling for overhangs etc.

Right now though I am looking for the Gcode for the printer wipe that runs a bead in front of the printer all the way across before printing, its priming thing.
i know its been posted, but searching isnt netting the right stuff.
thanks guys and gals.

Clough42 has gcode for a prime and wipe on his itty bitty double extruder thread:

I used this to start with but I didn't understand why one extruder wiped the length of the bed and the other one extruded onto the bed at z0 then wiped sideways for 15mm. so i changed it to prime both and wipe both along the side of the glass. Maybe C42 can explain what I'm missing about it.
