Features: 1) CNC hollowed out full metal shell, high-quality accessories, high precision, good strength, not easy to deform, high temperature resistance2) Hollow shell bracket design, design, light weight, less inertia3) CNC POM gear, reduction gear design, high transmission ratio, to achieve greater extrusion torque4) High-quality hard steel nano-coated gears, wear-resistant, good precision and 5) Moons 36 motor with 8 teeth, good thermal control ability, low heat generation and large torque. There is a PTFE tube metal joint at one end, which can be adapted to more models at a short distance1. Name: CNC Metal Mini Extruder2. Applicable models: VORON, -10, CR10S, -10 4S, -10 5S, -10 MINI, -20, -2, , PRO, V2 , Gasherbrum . It will fit almost all FDM 3D printers if you can design the mounting bracket.3. Processing technology: CNCPrint model download link:https:\/\/.thingiverse.com\/thing:4974509Note:It is necessary to modify the E-axis step value of the extruder, for example: the E-axis step value of Ender3 is 870.1) The maximum driving current of the extruder is 1A, and it is recommended to use it at about 0.8A, which will not cause excessive heatThe reason for adjusting the current: to obtain a more suitable torque to prevent the motor from overheating2) firmware modifies the extruder pulse (8 teeth 36 motor settings) 1: Modify the extruder pulse by firmware:#define DEFAULT_AXIS_STEPS_PER_UNIT { 80, 80, 400, 870 } 2: Send G code (can be sent by slicing software ):M92 E870M5003) 10-tooth 36 motor pulse value: 6914) Klipper firmware modifies the rotation_distance valueMaterial: Aviation aluminumcolour: As shownPackageContents:1 x Mini Extruder1 x Accessory packageOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +\/- 1-3cm.
