Hi. My hemera extruder does not extrude well. At 5mm / s, fine. At 15 mm / s it makes some noises that it seems that it is going to break and the filament gets stuck and also the gears are "scratching" it. If I speed up ... worse. https://drive.google.com/file/d/1CseFwI5fIRX9vGcmrgzXl85WxCT41_2-/view?usp=sharing https://drive.google.com/file/d/1TtNUiasmdbochvjA5BH2WTbHlmA7d0R4/view?usp=sharing https://drive.google.com/file/d/1sVGva8bXDzXdGA7mlvVrjJlN4tb3bhPy/view?usp=sharing Does anyone know what may be the problem? Any solution? Thanks.
