CR-10 Extruder upgrade...

[The Hat]

I set out to improve the Extruder performance on my CR-10 by drilling out the hole that the filament passes through before it goes into the Teflon tube that leads down to the hot-end.

I made the hole big enough to allow me to screw a steal 30mm throat (Normally used in a hot-end) right into the plastic block that sits on top of the Extruder motor.

I used a throat that had a small Teflon tube inside it and then added a heating block to it, (Cut in half) which allowed me to fit the Pneumatic Connector to hold the Teflon tubing.


Then I fitted a new Aluminium easy to use arm bracket with an adjustable nut to help increase the pressure on the little filament bearing, I had another Aluminium arm for the other side, but it didn’t suite my current setup, so didn’t use it.

Once assembled it came together nicely and I tested it a piece of green filament before re-attaching the Teflon tube again, the proof of the pudding will be using it to print something, but I’m confident it will work as it’s supposed too..

OK. Now you are just showing off.

I have no idea what the contraption does or why it has a spring, but it looks good and your creativity is great. Hope it works as desired!

I’ve just finished upgrading my Ender 2 with much the same parts as on the CR-10, but this time I decided to use all the parts as they were intended.

Now both Extruders are looking good as well as working better..

Leave it to you to push the envelope.

Anyhoo... looking good!

Wow, what an interesting use of spare bits!
