So for the last two years I’ve been working on my ingentis/eutathios build. I’m a down to hotend and extruder and electronics. I plan to use e3d v6 and was curious of the ptfe length that everyone is using.

Ptfe tube from extruder to hotend

Mine is right around 900mm. It could be made shorter… But I opted for the most gradual arc instead of shortness. With the Bondtech extruder retraction is so crisp I have no problem with the long Bowden even on small features with lots of retraction.
