Manual: Explaination PTFE tube from holder to hotend is missing and when to use which tube.

[tkalbitz]

It is unclear when to use bowden and when to use PTFE tube. Both are in the manual, but bowden tube is never mentioned (quick search in the manual showed no result)

Additional questions I had: When to use which PTFE tube. Is a two part setup: One PTFE part to the coupler a second from the coupler to the hotend? Answer no you just push the PTFE tube from outside into the coupling to the hotend and into the extruder. This step is missing as "last page" of the manual.

After a few days someone pointed out that on page 313 the PTFE tube should go in the circular cutout in the holder. I was thinking the square cut out is for a prealignment for the PTFE tube.
