      Looks like you could also use a modified heater block with two heater cartridges, and use the same nozzle for high flow and low-oose depending on whether both heaters or just the lower one is powered?
      (Although maybe it would mean the heat break is higher than optimal)

      i think it's a good alternative to the full volcano. I am wondering what the tool is called/where did you get the tool for holding the block to help install/remove the hotend at 6:30-6:35 in the video?

      No, the cheapest option I found for the nut was $20 or more. For less than that I can get the brass nuts or even get a volcano block. If the nut was cheaper, I would heavily consider it.

    Stefan, your suggestions worked perfectly for me. I used a Volcano long nozzle on my Ender 3V2 with 2 brass nuts to lock against the hotend block. After adjusting the Creality touch sensor and re-setting the Z-offset, it printed my test square perfectly. I've not made any redirect for the cooling air so it might require a little re-direction so that the air is pointing to the nozzle tip (as standard) and not on the extension. Next step is to turn up a bit of brass and make a silicone sleeve to optimise heating. It was always a pain to visulaize the printng process, now I can see the extruder perfectly on very small prints. Thankyou!

    I went to the hardware store today and picked up a handful of 6mm x 1.0 nuts. I filed the contact surfaces of a single nut flat, screwed it onto a 0.6mm volcano nozzle, and mounted it on my standard E3D hotend and heater block.
    The results have been amazing! I have been able to push my delta printer to 120 mm/sec speeds without any flow problems. I'm sure I can probably go faster, but considering that your method has already allowed me to go from reliably printing at about 70 mm/sec to 120, I am super happy!

    Great content as usual. Thanks. I recently covered my soldering iron to prevent my fingers getting burned by the long exposed heating section (cheap soldering iron). I used car exhaust tape, basically glass tape with some high temperature adhesive impregnated. The adhesive becomes like glass when heated and the hot part is well insulated, or better at least. The tape wrapped around my soldering iron now gives me more warning and time to yank my fingers away. I would think that high temperature fibre glass tape as used in stoves and other heating element wiring would nicely slip over the long nozzle and reduce cooling from the fan

    Thanks for once again being top tier with both your methodology and frontier thinking. You’re as always impressively thorough.
    So; while these tricks can be great for simply increasing the max flow rate drastically, the long melt zone will also cause more oozing and hence, a loss of detail and a severe risk of extensive stringing.
    To strike a good balance seems easiest doable by using a Bondtech CHT nozzle which I use today.
    As the cheap Chinese knock-offs are not made with chamfered sinked holes like the original Bondtech CHT, they cannot be recommended for anyone wondering if this is a viable economical shortcut. But to be fair, it is possible to actually do this yourself if you have the tools for it.

    I'd like to see a similar video showing differences between different wattage heater cartridges. For example: I find the standard 30 watt heater cartridge to be too weak to reliably run a Volcano, but now that there is a 40 watt and now even a 50 watt from Slice Engineering, it would be interesting to see how they affect performance even on a standard heater block.

    When you dont have a proper sock or if your sock is damaged you can repair it with high temp RTV automotive silocone. The temps will be plenty good and it bonds REALLY REALLY WELL... dont let it cure on your silicone work pads. You could coat the nozzle for the test and then peel it off of you want to change it. If you are super keen make a thinwall PLA form to fill with RTV. Peel off after cure and you have an encased nozzle.

  • @VagabondTE

    Hypothesis: There may not be very much of a heat gradient. Yes there will be a drop off in heat towards the nozzle because it's farther away from the heater. However, the filament is coming from above and closer to the heater. With the filament moving the temperature might be a lot more balanced throughout.

      This is not true. I did as he said. The printer does not print at the same temperature because the hotend is too cold.
      I managed to get it to print at a temperature of 10 degrees above normal. Only in this case it is completely incomprehensible what was the point of fencing all these crutches, if you could just raise the temperature.

    • @VagabondTE

      @@hate-conductor You're misunderstanding the experiment. He wasn't printing. He was running flow tests. He keeps the temperature the same throughout the video in order to find and measure the difference between the methods. If you tried one of these methods then, yes, you may need to increase the temperature to get consistent prints again. However, since you didn't say anything about flow or print speed it doesn't make any sense to call these methods "crutches". You might be able to print at a higher speed and not realize it. Or it might not work because of your machine and setup. None of this is a guarantee. Also nothing you've said disproves or even addresses my hypothesis. Nothing here at all measures heat drop off.

    I have purchased quite expensive Copper heatblock for my v6 thinking it would help melting performance. But after testing I found that it does not improve hot-end flow by any measurable amount. Copper heatblock even visibly increased ringing artifacts due to its weight.
    At these flowrates heat transfer through plastic itself is the biggest bottleneck in flowrate, that is why Bondtech CHT is so good.
    Maybe copper heatblock would be more useful with a CHT nozzle? Needs testing.

    • @CNCKitchen
      @CNCKitchen  2 ปีที่แล้ว +1

      The heat capacity of the copper will help to stabilize temperatures and are more suitable for higher temperatures. Though they won't help increase flow in probably 98% of cases.

    Stefan! Try the reverse of the "copper" nut! You were right about the gradient and increasing the thermally conductive cross sectional area of heat flow with real copper and then insulating it (even if insulation is just a less conductive plating like steel or nickel) will have better results since it will have a lower h value! Newton's law of cooling!!

  • @koenvanduffel2084

    Delta T is the highest in the top of the heater. By the time the filament enters the extension it's already heated quite a bit. So I'm the extension not that much heat needs to be added. Having the hottest bit on the top could actually be an optimum in heat transfer.

    • @reverse_engineered
      @reverse_engineered 2 ปีที่แล้ว

      The downside is that the temperature will drop significantly towards the end so even if the heater is at 210C, the nozzle tip may only be 200C, preventing you from getting that extra heat in. You could compensate by raising the heater to 220C, but then when you aren't extruding, everything will heat up to 220C. Ideally you would want to control the temperature of the filament as it comes out of the nozzle. So having the heater closer to the nozzle tip and having the cooler end of the nozzle at the top would allow you to preheat the filament before getting to the nozzle and heater block. This would leave less of the filament at high temperature and for less time.

    • @mckidney1
      @mckidney1 2 ปีที่แล้ว

      Which is why the copper results are so close to the results with nuts. The key element here is that the losses in the copper are not as big as the decrease of needed energy by the plastic. That will change as you said - longer nozzle and eventually the copper will actually cool the plastic.

    I would suppose that effect might be related to the bigger real temperature at the nozzle. I know, that you kept the measured temp same, but you might have changed the heat capacity of the system with all these additions, so old PID parameters resulted to a bigger real temperature, which affected extrusion results.
