Easy To Install

A very intuitive upgrade kit where the extruder faces the X-carriage, reducing the distance between the nozzle and the X-axis.

Leading Grip Power

The LGX is the Bondtech extruder with the highest filament grip, thanks to its large drive wheels that engage more teeth with the filament.
