This kit consists of the following replacement transmission parts:
Main shaft
Main gear
Set screw
Primary gear
The BMG Reverse integrated transmission gear was designed in collaboration with MirageC, the creator of HextrudORT, to solve the problem of oscillation of the main shaft assembly and the primary transmission gear held by a set screw.
As MirageC explains in his video, the eccentricity of the double main gear and the oscillation of the primary drive gear help explain the surface irregularity found in all 3D prints.
To minimize these (in)tolerances, the following improvements were made:
Double main gears with tighter tolerances
Press fit on the main shaft with a new method
The main shaft and main gear are machined in a monolithic set of steel.
Note
CAUTION. The primary gear is reversed, so it is NOT compatible with the Bondtech BMG extruder.
From the center of the filament teeth to the end of the shaft: 14mm - 13mm
Number of teeth of the transmission gear: 17
Length of transmission gear teeth: 4mm
Main shaft/transmission gear material: Hardened steel
Material compatibility: Flexible / Rigid / Abrasive
Number of main gear teeth: 50
Length of main gear teeth: 3 mm
