About this model

(10/19/2016) I did retraction calibration for B'struder. Extruder drive: B’struder Kysan Nema 17 5.18:1 geared stepper motor, 2.4 V, 1.0 A config.g of RepRapFirmware-dc42 1.12a M92 411.230 M201 X4000 Y4000 Z4000 E3000 ; Accelerations (mm/s^2) M203 X15000 Y15000 Z15000 E15000 ; Maximum speeds (mm/min) M906 X800 Y800 Z800 E800 ; Set motor currents (mA) M92 411.230 Retraction setting in Slic3r 1.2.9: Length: 3.4 mm Z Lift: 0.4 mm Speed: 15 mm/s (10 mm/s and 20 mm/s give similar result.) Retraction after layer change: on Wipe on retraction: on Filament: eSun PLA 1.75 mm Layer height: 0.2 mm Printing speed: 20 mm/s Travel speed: 250 mm/s 190 degrees Celsius gave better result than 180 degrees Celsius. Why?! (3/16/2016) White one was done by RepRapPro Fisher last year. There was huge improvement…
