Nice German BF20 CNC Conversion

Last modified: February 21, 2024

I was truly impressed with the combined belt housings used to drive the ballscrews, along with other great features in this German BF-20 CNC conversion.

Metal component with cylindrical protrusion and flat surface.

Nice clean install, well protected from flying chips...

A rectangular piece of metal with three circular holes at an angle on a blue background, with a silver aluminum or stainless steel finish.

A rectangular metal part with rounded corners and two circular holes on a blue background.

Plates on the right are pocketed for the reduction timing belt. Plates on the left mount on the machine...

Small metallic device with cylindrical shape, flat top, and longitudinal grooves.

Stepper power connection...

Silver metal device with rectangular shape and small circular hole.

Another view of the guts...

Metal component with knurled knob and adjustable screw.

Manipulating the belt onto the big timing gear is going to be a little bit finicky, but not too bad...

Metal component with blue cap and silver bolts.

Neat little Hall Effect (proximity switch) limit switches...
