Reddit reviews WAHHING 10PCS 2mm thick Heater block cotton Safe Working Temp less 300°C For 3D printer Hotend

You can try insulating your heater block. There's cotton insulation that you then wrap with kapton tape. Which is how my maker select came. Or you can get silicone socks, which will depend on your hotend. These come with new e3dv6s and work well too

This stuff? Pretty sure it will mess with your temperatures without, not sure how much, and you may be able to tune your PID to compensate.

You took apart the hot end. I am assuming to remove to the nozzle for cleaning? There are two threaded holes in that picture. The larger one for the nozzle, and the smaller one has an L shaped bracket used to hold the thermistor in place. The thermistor goes into the unthreaded hole NEXT to the threaded hole. The thermistor wires look bent in that photo because the L shaped bracket squashes them.

Here's two links you will need to replace the insulation material.

reinstall the nozzle, tightly but not too tight. re-install the thermistor and L bracket. Then wrap everything with the insulation and use the 1/4" kapton tape to hold in insulation in place.

10 Pack for $7.00

Right now I'm just using some Kapton tape:

Later I'll add a silicone sock if I can find one, or maybe just some ceramic cotton:

You can print without it. It's not too expensive to replace and it helps keep the temperature stable and use less power(leaving more for the bed heater). You'll probably want some polyimide/kapton tape too.

There's some on amazon, 10 pack for $8, if you prefer to use Amazon for things.

Thank you. I didn't know this was a thing. 2mm thick heating block cotton

I found these https://www.amazon.com/gp/product/B01LAYCRAA/ref=ox_sc_act_title_1?smid=A256LC8UNAA9S0&psc=1

Did you have to change anything with the print head so it won't break the glass?

Drop the PLA temp to around 203, add minimum layer time to around 15 sec on Cura. Bed also doesn't need to be that hot with the Buildtak


Use cura 15.04 instead of the Cura the V2 shipped with - 15.04 has way more custom options.


I did the blower fan upgrade for my V2.1: http://www.thingiverse.com/thing:1025471 which helps immensely in overhangs and small details like fingers

Also since your room is cold, consider upgrading your nozzle to all metal: https://www.amazon.com/gp/product/B01E1HANLS/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1


If you choose not to upgrade to all metal, consider using some nozzle insulation: https://www.amazon.com/gp/product/B01LAYCRAA/ref=oh_aui_detailpage_o00_s01?ie=UTF8&psc=1 you will need kapton tape for the insulation


The all metal hot end + insulation will help you maintain consistent temperatures in your cold room

Some items I bought from Amazon (don't buy the hot end pieces if you have a V2. They changed the hot end to an all metal one):

works great but I frankly only replaced it once, after I needed to replace it a second time I left it off and have not noticed a difference. Without the insulation it is easier to keep clean and to get the nozzle to seat nicely when switching nozzles.
