UniTak3D Dual Drive Extruder Gear Replacement Stainless Steel Extrusion Wheels for,Ender 3 V2,Ender 3 Pro,Ender 3,Prusa i3 MK2/MK3 3D Printer Double Geared Extruders

I bought a used MK3S recently and it had some issues with extrusion and so one of the things I did was replace these parts (along with some of the printed extruder parts) in an attempt to fix it, turned out to be the extruder motor but these worked perfectly and I kept the originals as spares (I run a few of these machines).

Not necessarily easy to install. It does work well.

While I like this style of extruder gear and have been using it on multiple printers, I found that the latest set of gears have had their teeth worn down to half thickness in <20 hours of printing. I'm not sure what caused this exactly, since this has not happened on a set of gears that I've been using for much longer. The printer that wore them out faster also prints faster and with more extruder movements. In both cases I forgot to add lubrication, which is definitely not helping.

no real clear instructions sent along on how to replace the gear. Just buy the complete unit

thx

After months of trying different settings, drying pla and replacing the heater, the uneven pla extrusion was due to worn extruded gears.Took 20 min to fit and now we are back to printing things I don’t need.

Ruote dentate perfettamente compatibili per la Ender6 Creality, gli ingranaggi originali dopo un anno si erano usurati e si inceppavano continuamente bloccando l'estrusione del filamento, ho usato il perno originate invece di questo perché quello originale ha un'estremità filettata e l'altra con la testa della vite, e di dadi non sono serviti.Ho oliato leggermente i denti degli ingranaggi (facendo molta attenzione a non ungere anche la zigrinatura che spinge il filamento) ed è diminuito di molto il classico rumore che fa l'estrusore.

Unos engranajes muy buenos, permiten buen control sobre el movimiento del filamento.

タイトルのとおり、BMGのエクストルーダの部品として、購入。入れ替えてみましたが、問題なく使えています。特に目立った特徴はありません。
