Was having clogging issues so I thought I’d replace and get the mythically good capricorn tubes. This is a good sign that I needed to.
and even if it were worn down that much it wouldn’t cause any problem as the entire tube is made of the same slippery stuff, it’s not a coating.
Would a larger inner diameter not cause the transmission of movement to be less direct due to bending and coiling inside the tube? This is probably mostly an issue in bowden systems
The hysteresis that the tubing imparts on the movement of filament is negligible at best. We’re talking fractions of a millimeter of difference; and it’s something that can be accounted for in your retraction quite easily. Remember that this hobby is LITTERED with people trying to sell you stuff. Be critical in your observations, because even most YouTube channels will tell you that [X] thing is GREAT because if they don’t, they stop getting free shit.
When it comes to pressure advance the difference between a bowden extruder and a direct extruder is more than tenfold. So no, it’s not “negligible at best”.
If the difference was negligible no one would put the extruder on the toolhead where the weight has a big impact on maximum acceleration
