SummaryYet another kustom kossel. this one is made for the quiet witout any compromise on speed. Main particularities of this custom build : speedy and quiet (relatively to my other printers like k800, k8200, 3dr Simple) many damper printed in flex. (foot, fan and motor damper, etc) Openbuild v wheel roller carriage e3d raised effector with probe adjustable bed level huge build area (+/-250mm diameter and 300mm height) light are integratend in the 2020 extrusion rem: not included in files : richrap extruder, standart 2020 top corner,Print SettingsPrinter: K8200 for flex , 3dr Simple ,Sardukar and k800 for the restRafts: NoSupports: YesResolution: 0.2Infill: 30Notes: The stronger the better! Except for all the damper parts : printed in flex with 2 perimeter/top/bottom and 10% hexa infillPost-PrintingMarlin configuration.h define DELTA_SEGMENTS_PER_SECOND 160 define DEFAULT_DELTA_DIAGONAL_ROD 309.125 define DELTA_SMOOTH_ROD_OFFSET 240.9 define DELTA_EFFECTOR_OFFSET 30 define DELTA_CARRIAGE_OFFSET 35 define AUTOCALIBRATION_PRECISION 0.03 define MANUAL_X_HOME_POS 0 define MANUAL_Y_HOME_POS 0 define MANUAL_Z_HOME_POS 313.2 define HOMING_FEEDRATE {200 ✱ 60, 200 ✱ 60, 200 ✱ 60, 0} define XYZ_ACCELL 5000 define E_ACCELL 2000 define DEFAULT_AXIS_STEPS_PER_UNIT {80, 80, 80, 700} define DEFAULT_MAX_FEEDRATE {500, 500, 500, 100} define DEFAULT_MAX_ACCELERATION {XYZ_ACCELL,XYZ_ACCELL,XYZ_ACCELL,E_ACCELL} define DEFAULT_ACCELERATION XYZ_ACCELL/3 define DEFAULT_RETRACT_ACCELERATION E_ACCELL define DEFAULT_XYJERK 22.0 define DEFAULT_ZJERK 22.0 define DEFAULT_EJERK 15.0 2020 and Rods size9 Pieces of 2020x360mm 3 Pieces 0f 2020x750mm Rod Size : +/-310 mmHow I Designed ThisI've print some part in rubber like filament to reduce the overal noise of the printer. the feets, all the fan damper, motor damper, fan holder for the ramps and the extruder spacer are made out of flexible filament to reduce vibrations. I've also try various system for the sliders. the quietest are delrin V wheel (openbuild) directly on the 2020 profile.VariantI got magnetic vertion of the effector and carrier also. but i don't like it. When printing at high speed magnet have tend to get loose when the effector change direction.
