A2 printer only: longest pipe is to be placed on feeder #1
(rightmost, when looking on the rear side).
After fitting PTFE piping on each filament feeder, you can
mount them on the printer, feeding the piping thru the
rear openings, just above each feeder position.
Each feeder has a “mandatory” position: refer to below
drawing to understand feeder placement on each printer
