3D Printing Extruder Upgrade Accessories BM Nano-Coating Helical Gear Kit High Strength CNC Skeletonized POM-Gears Applicable to VoronLegacy Voron2.4 VoronTrident CW1 CW2 Bczamd

I'm using this with a CW2 extruder in a Stealthburner. It's a perfect fit in my extruder. Using the provided shims, the extruder gear aligns perfectly in the filament path and turns freely. The gear and shaft are a single piece so there is none of the runout you would get from a gear that's fixed to a separate shaft via grub screws, and no chance of the gear coming loose from the shaft. The helical gears also mesh well and seem quieter than the usual spur gears used in BMG and clones.Someone complained that the drive gear that mates to the motor is plastic, but that is the case for all BMG and clones. This drive gear seems to be made of durable POM and with machined cutouts to reduce weight.So far, I'm verry happy with this gear kit.

it lines up with the filament hole but the shaft slips away from the motor and starts to making a clicking sound and slipping, adjust the screw on the extruder and it stops clicking but also stops extruding, no way to adjust the spindle, if I remove the font of the extruder then I can push the spindle back into place with a screw driver just by pushing it with no force, it works until the next print and it slips out again.

Not compatible with Voron Stealthburner. While the body is metal the main gear is not metal but plastic

Huge improvement over clone bmg gears. Get a few extra shims to get the position and endplay perfect for the housing you're using. Clone gears had .005" runout on the injection molded drive gears and .003" on the hobbed portion. These new ones have between .0005 and .001" on the hobbed portion. There isn't a hub to measure against on the cnc milled drive gear but being it's not injection molded, it is most likely better. The extrusion consistency, on wall especially, is very noticeable!! The helical cut gears are significantly quieter on retractions too!
