Filament tube attached to X-axis cause filament tangle when Z-axis moves down before print. That's why I designed an alternative tube holder which is mounted next to spool holder.
Made in Fusion360.
STEP and F3D included.
Update 2024-03-27:
I forgot to mention that you probably will need a slightly longer tube. You can use a regular 4-3mm PTFE tube (4mm outer and 3mm inner diameter). I used a longer AMS Lite tube from Bambulab (4mm outer and 2,5mm inner diameter) which worked also just fine.
In my setup I guided the tube BEHIND the Z axis.
However, some user will notice that their tube needs an different guidance. So when guiding behind the Z axis don't work for you, please try this additional guide designed by @S1ou → https://makerworld.com/en/models/224955#profileId-242856
