Trianglelab Matrix Extruder somebody?
-
Here is a watercooling mod for hemera I've build for my printer Hydra:
-
@rabbit : Now THAT is quite a nice design! Would you mind sharing it if I manage to find a Hemera?
Does anyone know if the Hemera gear train is for sale anywhere? The stepper, heat break and heat sink seem to be available in local shops, I don't need the V6 hotend stuff since I have plenty of that, so about the only part missing to build up a Hemera is the gears.

nsfw! but not easily replicated with basic tools/skills i guess
your rending perfectly illustrates why my optimistic idea of just milling a flat and bolting on a cheap water block isn't practical with the porturtion for the bearing.

well now you have a reason to build a cnc machine

i have one of the finest 300x400 cnc routers made from chinesium, it just needs a lot of tlc
tbh i'd be more likely to try to cast it in alu using lost pla, some day

After an exhaustive search for a Hemera or a Hemera in replacement parts I gave up and ordered a Matrix LC. We shall see.
If E3D stocks Hemera's again before I need the second extruder I have some comparison. -
Mine is now at my country. Will Post Pictures!

I will pass the deep dell of doom aka "china noble scrap"
There are all kind of metal-extruder-body-as-heatsink extruders in the market, some predated Hemera. For example, those metal BMG's that are available for some time.
-
My 3D-printer adventure started when somebody gave me a Geeetech extruder and another guy gave me some 40x40mm aluminium extrusion. That Geeetech thing was The Definition Of Crap. Now, I know that most China stuff is at best a good starting point; they gave you a bunch of parts that they pre-assembled so you know how they shoudl fit together, but it is your task to deburr, clean and grease everything. But seriously, in the end the only thing that could be recycled was the heater cartridge. A complete waste of materials.
Switched to a Bondtech QR extruder, created my own hotend, and had a flawless experience which is worth more than a few bucks.
We'll see what happens this time.

i think there has been talk of a pancake version, but whatever issues they're having seems to push that back
The explanation I heard here (from dc42?) was that a larger stepper simplifies upgrades since it can use the existing current setting (not easy to change on some controllers).
Bondtech seems to do the 'right' thing and go with a smaller motor on their upcoming integrating direct extruder. Probably similar to the 150g LDO they recommend for their BMG. It may be a nice upgrade for my printer.
They team with Slice Engineering to compete with E3D in the extruder + hotend market.

very nice. i think this will be better than the hermera.
copperhead heatsink
smaller footprint.but i kind of wish they included some screw holes in the from to mount a part cooling fan.
-
I like the Bondtech stuff. Was running the QR, now I am running the BMG-X2. Exactly zero issues with those.
The only thing I don't like about them is the plastic they use (lasersintered nylon?). It is fairly soft and it tends to deform slightly when used above a 100-110C bed in an enclosed chamber which also heats up to 60C or so in those conditions. Internal stresses I suppose.That is why I am interested in the Hemera above Bondtech; housing is made of metal, gears are made of metal.
-
The new bondtech looks promising too. But I guess that the availability will be limited for a long time.
I have a bontech at the moment and I'm very happy with it. So I want to give E3D a try, I think it is worth the time to play with one of there products.
On the other hand seams the copperhead with a bondtech extruder a very promising concept as well.

just wait a few months, someone in china is gonna do a water cooled version of it

well you can use the copperhead with the hermera as well.
see toms review of it

thinking about the bondtech lgx a bit more.
the weight should be comparable with this

slap a copperhead on it and you can buy it today. -
Came today! Quality wise its seems very good. Mostly Metal. Only the Lever is out of Plastic.
I would order a spare heatbreak. Looks very delicate. But its nice to see that its not hold by only a grub screw. They machined a extra inlay for it!
-
By using the surgical stainless tubing at least they have a heatbreak with a very smooth inner wall and low heat transmission. Works very well. I did the same on my homebrewn hotend (but I used some RVS304 M2 threaded rod to support that thin tube), and that one performed better than the Chimera I am running now, especially with flexibles.
That lever looks like it is prone to deform in slightly higher ambient temperatures, but judging based on the pictures it is fairly easy to replicate in metal.
Thanks for the pictures!
(my LC one has not shipped yet) -
Does not look bad, thanks for the pictures. Let's we how the pair I will get look like.
