I’m sorry if this has been discussed before!!! I’ve Ben doing a lot of printing using carbonx carbon fiber nylon, and the filament has worn the extruder drive gear down to where it needs to be replaced. Does anyone know about hardened drive gears or at least replacements? Plan B would be to custom b…

Never heard of a gear needing replaced. I’ve printed a fair amount of CF PLA, not nylon. A pic would be interesting to see…

That would be a bit surprising, since the filament isn’t rubbing on the extruder gear. The extruder gear should grip and push the filament without slipping. Although if the gear does slip on the filament, I could see the teeth wearing rather quickly on abrasive filament. If the gear is slipping, …

My gear has been wearing as well, I’d be interested if there’s a solution.

Hard be imagine that gear wearing. I do notice filament debris buildup every so often that leaves a mark down the center of the gear, but a stiff brush cleans that out.

Snapmaker sells a Lot of spare parts they do not list on shop when you kindly ask the support. They offered me all i wanted recently.

I can confirm that my extruder gear wears on the 3D printing module (A350T in my case). I use Overture Matte PLA exclusively, and I’ve worn out not only 1, but 4 gears. I have reached out to Snapmaker support to buy the motor independently, and I just replace it each time the gear wears out. It fee…

@sadekbaroudi Can you share how you contacted support? My extruder gear looks worn down and I have been having failed prints because the filament stops coming out and when I open the head unit, the filament is worn down at the gear line - and the gear looks worn as well. I don’t see an obvious way…

Btw., you can coax a bit more life out of the feeder gear wheel: [image] Inconsistent Layerlines Snapmaker 2.0 I wanted to give feedback! My Layerlines really came from Extruder Gear slip. As suggested I put 3xM3 washers between the acrylic piece and the heatblock. This…

That’s a great idea. I should have two replacement motors coming soon, but in the meantime, “shifting” the gear over to place the filament on unworn portions of the teeth is a great suggestion.
