    Hi
    I have a chimney with 500 mm of bowden tube. the retraction tests come out at 2.8mm 50mm / s and 150mm / s travel speed.
    but at the time of printing, when it reaches a height of z of +/- 12mm it starts to get stuck and to bite the filament. My extruder is a titan. Could you tell me what is wrong?
