Bondtech LGX Lite Extruder (with motor)

8 features of this Bondtech eXtruder:

• Larger drive wheels, for increased filament grip;
• Filament pre-tension lever, for repeated results;
• Drive wheels’ maintenance windows, for easy cleaning;
• Compact, light & centered filament path, for increased performance and compatibility;
• Multiple mounting hole patterns, for easy and flexible setup;
• Compatible with Nema14 round stepper motors;
• Craft boxes without bleaching & no coating.
• Nylon housing with no dyeing or other chemical post processing.

3D Printed Housing using PA12

The housing parts are professionally printed with polyamide 12 for maximum strength, precision and higher temperature resistance.

To lower our ecological impact Bondtech is reducing use of chemical dyes. This part is supplied with a wax protective coating to lower sensitivity to moisture and grease, while remaining fully functional.

For Klipper users

rotation_distance = full_steps_per_rotation * microsteps / steps_per_mm

rotation_distance = 200 * 16 / 562

rotation_distance = 5.7

The above calculation assumes the following parameters:

stepper motor is a 1.8 degrees motor hence 200 as full steps per rotation;

microsteps are set to 16;

e-steps value recommended for the LGX® Lite is 562.
