3ntr A2 - Filament Feeder Installation; Mounting PTFE Piping on Feeders; Routing PTFE Piping Through Printer

Each filament feeder must be fitted with its own PTFE piping before mounting it on the printer.
Screw the threaded part of piping on the filament feeder, as shown in fig.2, taking care about:
• piping won't touch bronze feeding roller
• piping won't be overtightened, stressing (and possibly narrowing) the PTFE pipe
A2 printer only: longest pipe is to be placed on feeder #1 (rightmost, when looking on the rear side).
