Hexagon Hot End?

Haven't printed too much but the finish is much nicer with two fans and the install was pretty easy. The only things I want to do are to make a shroud for the hotend fan, clean up wiring, and make some sort of adapter so it is easier to feed filament, right now it is pretty difficult to find the hole since there is a gap.

Cool, my hexagon is on its way along with the xxl lcd and some new couplers as mine are a bit wobbly. Hoping it may arrive today but will probably wait till the weekend to play with it

 

Tracking update due Monday noooooooo :-(

 

Have done 6 PLA prints using the Hexagon + rubber insulator (10-12 hours) without any problems. The temperature curve is very stable at 200c.
I`m using the Bulldog Lite extruder + Hexagon (1.75mm)

 

I did 2 1h20min prints last night with excellent results again. It's a bit hard to see the finish/quality in clear PLA but trust me, it's so nice I just love looking at the prints. 1 million % better than the stock hotend.

 

You beta testing that or did you buy it from reprap discount?

 

Nice. What clear PLA are you using?

 

It's Standard PLA from https://www.3dprintergear.com.au
I have green PLA which works well too and black and silver ABS which I haven't tried yet. Got some bits to print before I embark on the ABS journey.

 

I`m beta testing the Hexagon + Rubber insulator/jacket.

 

The filament cooling fan is not active in this print (I`m not done configuring the Marlin firmware), so the bridging is not the best.
My setup:

• OrdBot Hadron + Rumba controller running latest Marlin software.
• Hexagon + Rubber insulator/jacket (Beta testing)
• One 40mm fan is used to cool the hexagon heat sink (always on)
• Bulldog Lite direct drive (1.75mm)
• Winbo PLA
• Hot end 200c
• Heated bed 60c - Glass plate + Puzzle conserver
• Layers = 0.2mm

Some smell from the rubber isolator in the beginning (2-3 prints), but the smell disappears after a while.
The temperature curve (in Repetier host) is very stable at 200c although the printer is placed near an open window.
Some fine tuning/leveling + have to activate the filament fan before my printer is "perfect", but the Hexagon has worked flawlessly so far.

Big thanks to Elvira that lets me test the hexagon/isolator..

 

i think i missed the post but what is this rubber insulator?

 

It is a insulator for the heated block, made of a special rubber that can handle up to 400c.

 

cool. i assume it is to keep stable temp. does it come with all the hexagons?

 

not sure but think it is still under beta testing

 

How is your thermistor secured in place?

 

On my Hexagon, and E3D before that, I have used Copper Silicone.
It keeps the thermistor in place without using Kapton tape + it can withstand up to 370c
+ The Rubber jacket/insulator helps securing the thermistor in place.

 

You did it a hellova lot cleaner than I ever could lol.

 

+ the Silicone stays soft, so it`s simple to remove the thermistor later if needed
I do not like using Kapton tape..

 

Yeah you can see my lovely thermistor epoxy here: https://cloudup.com/ib2GvMT5yu1
