RE: Tungsten carbide nozzle leakage

Yes, they're E3D V6 compatible, which is what the adaptor is. Caveat is that I know nothing about this heater block but I will check it out because I'd love to use my TC nozzles on my Mk4's.

I will use another heatbreak and the copper plated heatblock, will update if leakage stops for me!

What heatbreak?

found a copper titanium alloy v6 adapter from china, dont know if it is legit

RE: Tungsten carbide nozzle leakage

Okay, we're waiting with bated breath for your report. I've ordered a couple of the coated heater blocks but I'm concerned that the nozzles tighten against the adapter, and the adapter is not made of copper etc.

RE: Tungsten carbide nozzle leakage

I use this procedure when tightening the nozzles. I insert a V6 adapter into the heating block from one side. And I don't even have to tighten it too much. I screw in the nozzle from the other side of the heating block. I will warm up the whole set. But now watch out! When tightening the nozzle, I do not hold the heating block, but put the side wrench on the hexagon of the adapter and use the second wrench to tighten the nozzle with the appropriate torque against the adapter. I use a quality key to hold the adapter, not pliers, otherwise there is a risk of destroying the hexagon faces. If I were to hold the heating block, the adapter can screw out of the heating block by friction between the surfaces and I will never get a seal. The sealing surfaces of the nozzle and adapter are not in the threads, but on the front surfaces of the adapter and nozzle. And for checking, there should also be some small gap between the hexagons of the nozzle and the adapter and the heating block when everything is tightened as it should be. I also ordered a copper heating block, so I'll see how it behaves. A small problem will be that the copper block is heavier, so I'm curious how the IS will react to that without an accelerometer.

I asked prusa, and either you have to calibrate the IS yourself, or wait for their solution. They seem to be developing a system for using the accellerometer. So I will probably use the machine without this setting until they have fixed it

I've been using my 3DMakerEngineering now for 50+ prototypes of a part I'm making and have had no leakage or issues with the new plated copper Levendigs heatblocks. I've run Carbon Fiber PETG, regular PETG, PLA, PC, and even some TPU through so far, so it's looking good.

And I promise I'm not a Levendigs representative lol I had never even heard of them until I started looking for a solution to this leaking problem.

Not sure if you're referring to the copper plated heatblock, but I've been using the IS profiles with it and haven't noticed any print quality issues stemming from it.

That's good, the copper block is on its way and I'll let you know how it went with the IS when I install it.

RE: Tungsten carbide nozzle leakage

Good to hear, @8bitsaint. I have the blocks coming, but I'm leaving for a few a month in the sunny south tomorrow so won't be able to test them anytime soon.

With the copper heatblock and the titanium copper alloy v6 adapter no leaking nozzle with over 30 hours of print time.

This seems to be the solution so far!!

That is great news. I too ordered a titanium copper adapter from AliExpress so maybe I got the same one. I bought my plated copper heatblocks from the Netherlands ( Levendigs ) and got my TC nozzle from West3D as the other places mentioned here were out of stock or more expensive. What torque specs did you end up using or did you just wing it?

Thanks

RE: Tungsten carbide nozzle leakage

Can anybody share their experiences with that heater block? I am highly interested in that thing as I have some very nice V6 nozzles I can't use on my MK4 because the combination of the stock block and the Prusa adapter proved to be a leaky mess for me. If that thing should solve the issue without requiring me to re-tune all my filament profiles, I would immediately buy that part.

the heatet block works awesome for me, waiting for the inout shaping update from prusa though, since the heatblocks adds a substantial amount of weight. 

The input shaping profile works decently, but not perfectly, a little bit of ghosting.

I havent messed with any profile though, didnt need to change anything

RE: Tungsten carbide nozzle leakage

I am using this torque wrench https://www.sliceengineering.com/products/nozzle-torque-wrench-1-5-nm (rated at 1.5Nm) and have also used this one https://www.printables.com/model/24539 successfully (would still be using it but got the other one as a gift.

I'm snowbirding south through the end of March but the new heater blocks have arrived back home, and I can't wait to put them to use. Well, in the meantime I've invested into a boatload of Obxidian nozzles for my XL5 and my Mk4's so the need is not as urgent anymore but it will be useful for my 0.25 and 0.8 mm nozzles. Will probably do the IS recalibration. Not expecting much because even with stock config I prefer to run the non-IS profiles as they all give me consistently better results. Unlike the Minis, which just rock on IS.

RE: Tungsten carbide nozzle leakage

Thanks for the info. I see at that link you can print 4 different rotors for various torque specs and one guy wrote this:

thanks for sharing. I printed it in PETG, worked great. the rotor generates the following torque:

1.2mm --> 1.14Nm

1.3mm -->1.48Nm

1.4mm -->1.99Nm

1.5mm --> 2.30Nm (edited)

 

So what rotor are you using for what desired torque spec using this tool? Also, are you or anybody using a silicone sock after you upgraded the heater block and adapter and added a TC nozzle? I bought some and was planning to use them for keeping the heater block clean in the event of a misprint etc.

Thanks!
