E3D Hotend Insulators  

Re: E3D Hotend Insulators

Just be aware of this:

"Note that these will not work with the older bare thermistor style heater blocks."

Re: E3D Hotend Insulators

I wonder if the e3D v6 block is the cartridge style required for the silicone sock. Comparing the photos in the PR documentation would make me think they are: https://d17kynu4zpq5hy.cloudfront.net/igi/prusa3d/YflV2SxXEOYp2rjN.huge is from the assembly guide.

Re: E3D Hotend Insulators

That picture is the old style.

Re: E3D Hotend Insulators

Upon more thorough study about the insulators, dang, indeed it's different. 🙁

I wonder if e3d will be phasing out the older block design. I can't gather from their webshop how that cartridge thermistor differs from the one used in the old design.

Re: E3D Hotend Insulators

The old design is simply a glass bead, whereas the new one is encased. Plus the heater block is slightly larger in one direction.

Re: E3D Hotend Insulators

I'm mostly wondering if a swap would require a different thermistor to be selected/defined in the firmware. If not, it's a relatively simple drop-in replacement, otherwise people wanting to use this will probably have to build firmwares from source themselves.

Re: E3D Hotend Insulators

It's the same thermistor (Semitec 104GT), encapsulated. No change in firmware required.

Re: E3D Hotend Insulators

Excellent to hear. Thanks for confirming PJR.

Re: E3D Hotend Insulators

Ordered some. Now whats the best way to clean the hotend? Acetone?

Re: E3D Hotend Insulators

Acetone will probably work best if the residue is from ABS plastics. That, and some elbow grease and patience for scorched residue.

Re: E3D Hotend Insulators

Only used ABS and a bit of PLA now and again. I will try acetone and update when they arrive.

Re: E3D Hotend Insulators

I would not rush out and buy these guys. I have had nothing but problems with them. These do not stay in place no matter how you go about fitting them. After a long print I came back to check it and 3/4 the way through it had decided to turn itself sideways and catch all the filament. There is no 100% safe way of fitting them. They simply hang on the hot end. Being silicon and a loose fit unless you run the printer at 20% it will move.
If only there was a heat proof cable tie that would hold it in place. 🙄

Would be interesting to see how others have fitted theirs though incase I am completely wrong. 😉

Have you tried Kapton tape?

Have you tried Kapton tape?

What is Kapton tape? Is it available world wide? Im UK. I cant say I have heard of it.

Kapton is a trade-name for a thin, heat tolerant material. Some use it to cover heated beds. I've got sheets of it over my heated aluminum bed on a Geeetech G2S Pro Delta printer.

Often you will see it on the leads to the hot-end itself. It is usually a yellow/gold color.

This article describes some uses and shows some photos. It can be purchased at Amazon, or many places where 3D printing supplies are sold.

Oh I see. Yes that is genius, why did I bother buying these socks!

Going to look at getting some of this Kapton tape. Thanks John and gz1 😉

It isn't an i3 MK2, but another fellow on the Geeetech forum reports good success with his sock. He does have a layer cooling nozzle that might be helping holding the sock in place: https://plus.google.com/+JasonMcMullan/posts/ZqwipaTQesD

I just ordered a set to try with my new i3 Mk2. For under US$10 including shipping I'll see how it goes. I really hated how my hot-end and nozzle got covered with PETG.

It's important that people be sure they have the right Hot-End for the e3d socks... It MUST be an e3d V6 Full hotend with the new style cartridge thermistor... otherwise they won't fit properly. Also the nozzle must have been fitted exactly as recommended by e3d with the half-turn of the nozzle back out from the heater block.

Because they look cool? 😎 😆 And I mean... come on... socks for your printer! 😀

Have you double checked that you have the newer style Hot-End (with cartridge Thermistor)?
