Congrats mate! Thank you for all your hard work on maintaining this little piece of the internet for us!

But the ambiguity comes from the crown ignoring the original, Te Reo document, in favour of the translates English version, then ignoring that as well.
I want these to become a thing, because they’re awesome. But I doubt it actually will.
Plus, there are much more efficient ways to move large numbers of people. Still, ground affect craft are neat.
It’s all good mate! Thanks for the suggestion. When I first started printing I had that exact issue.
Hey mate, I keep my filament in a dry cabinet at 5ish% humidity, and I’ve had the same results with two different filaments in there. I even chucked my filament in a food dehydrator at 40C for 12h with no effect. I’m pretty sure the filament is dry!
I love these! Thanks for sharing!
After sleeping on it, I remembered that my new heatbreak doesn’t feed the bowden all the way to the end of the nozzle like the stock one does, so I’m pretty sure I have it seated correctly. I’ll check it though, many thanks for the info! :)
I know esun is quite popular, but I never tried it.
I’ve generally had the best results with it. Ironically, before the upgrades I had almost no stringing.
I’m using a 0.4mm nozzle. I probably should have mentioned in the OP that I didn’t have problems before, but the upgrades have happened in addition to moving to Orcaslicer.
Now I’m worried if I’ve got my Bowden tube seated in the hotend correctly…
Thanks for the reply mate!
I didn’t think to mess with z-hop - I’ll give that a go, and I’ll do some testing to make sure the Bowden is seated correctly and the wipe on retract is actually happening - thanks!
The print in the image is a ‘torture test’, and just something I had on hand to illustrate the issue. I’m actually not fussed if there is still some stringing at the top, but other detailed prints were getting it pretty bad, including retraction towers.
I expect this to change. The problem is they pushed it out for light vehicles before it was ready. If it’s going to work anywhere, it’ll be heavy vehicles, shipping and aero.
But hell any new zero emissions tech is ok by me. Just…something other than dead rotten dinosaurs.
Look again. I’m not talking about light vehicles.
A BEV truck can weigh up to 5 tons more than a FCEV. Why would that not be a case use for hydrogen? Now scale up to a ship where volume is no issue. BEV shipping is a non-starter.
New battery tech is fantastic. But why would you assume new battery tech, currently prohibitively expensive, will come down with scale but hydrogen won’t?
Ammonia is significantly more harmful in the event of a leak. Yes, it’s more hydrogen dense than pure liquid hydrogen.
Ultimately I don’t see a reason to dismiss hydrogen like some are doing. Is it the perfect solution in all cases? Of course not. Does that mean it is not a viable fuel source for transport? Absolutely not.
Scale solves most problems. Hydrogen also has other uses, such as steel production, which further increases the scale.
For light vehicles batter EV is likely to be the leading type for some time, as volume is more of an issue then weight for the ranges we need.
That’s not entirely true. If you are purely looking at $/kWh then yes, of course this is the case. However that is not the only consideration when it comes to transport. Weight of the drive unit, use of rare earth metals, lifespan of the drive unit, energy density by weight, speed of recharge, ease of transport energy, and more are all considerations.
I’m not arguing that vehicles will become hydrogen electric. I agree they are not suitable without some serious technological advances. What I’m saying is that at a certain point, larger vehicles (trucks, trains, ships, even aeroplanes) will become more suitable to hydrogen.
I’m all for increasing rail and coastal shipping for cargo. Having lived overseas, it’s criminal how much we rely on trucks here.
I can’t find the exact figures, as it depends on battery range and battery tech. One study I’ve seen found a battery truck would weigh over 5000kg more than a hydrogen-electric version.
I’ve also seen figures of double the weight for a Li-Ion battery EV compared to HEV at ranges above 300 miles.
Of course it is, don’t be daft.
Price will come down with scale. Currently hydrogen is only produced at a very small scale. As production increases, price will drop. Simple really.
Freezing pumps is a problem I’m certain will be solved. In its infancy, EV charging stations were slow. Look how far the technology has come in a short number of years. As uptake increases and infrastructure is built, I am certain these problems will be overcome.
Absolutely. If there was the political will in this country, we would have an excess of cheap, renewable, power.
Yes, as I said above, this is true because a) hydrogen doesn’t currently have the scale to bring the cost down, and b) is more suitable for large vehicles anyway. It’s failure to be a viable consumer option doesn’t mean it wouldn’t work in mass freight transport.
There are problems with these articles, and it almost always comes down to scale. There currently isn’t the scale and infrastructure to bring the cost of hydrogen to make it cost effective compared to pure electric. With time that could change if there is a will to do so.
But regardless, as I mentioned in my other comment, hydrogen has a much better use case in large scale transport. Trains and ships, for example, where volume isn’t a problem and where the weight of batteries becomes untenable. This is, I think, where hydrogen will be viable.
I agree with you, and I think it’s interesting to look at why there is a short term uptick in youth crime.
