Tevo Tarantula Z Belt

thingiverse

This is how I got rid of Z banding on my print with Tevo Tarantula. The Leadscrew has been replaced by a belt on Z axis. Fairly simple ! You'll need some GT2 belt , 2 * 10mm pulley M5/16 teeth, one screw M5x30. To avoid Z axis falling down when Z motor is off and damage your bed, you need to tune some parameters in Marlin and in your favorite slicer file: MARLIN: Edit configuration_adv.h file, and replace: define DEFAULT_STEPPER_DEACTIVE_TIME 60 by define DEFAULT_STEPPER_DEACTIVE_TIME 90000 Edit configuration.h file and change steps/mm and feedrate for Z motor define DEFAULT_AXIS_STEPS_PER_UNIT {80,80,100,97.0874} // 100 define DEFAULT_MAX_FEEDRATE {225, 225, 5, 25} // 5 in Repetier/Cura: Disable in printers parameters "deactivate motors after end/urgency stop" For experts, Ending G-code to park the Z axis can be configured. It will avoid heater to damage the bed in case of power off after print completion. Example: G90 ; Absolute position G1 X0 Y280 G1 Z 0.5 ; laydown the haed on the bed Print Settings Printer: Tevo Tarantula Rafts: No Supports: No Resolution: .2 Infill: 40% Notes: PLA works fine
