  • 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.





  • There seems to be a general push against hydrogen electric transport recently. I agree that it isn’t suitable for small-scale transport, such as cars or even busses, but I do think there is a use-case for large transport.

    Ultimately the problem comes how do we get the electricity from the generator to the vehicle where it needs to be. Obviously batteries are more efficient, but they come with their own problems. They weigh a lot, which damages infrastructure, they require rare metals, they have a maximum capacity per unit weight.

    Of course they have advantages, but I think as the vehicle gets larger, and the charging time requirements drastically increase, I think there comes a point where hydrogen electric systems are worth looking at. Trains and shipping being the main ones, and potentially trucks.

    Of course, if the hydrogen is not generated cleanly then it’s moot, but the same is true for pure electric systems as well.

    Ultimately, I would like to see renewable generation that turns excess power into hydrogen for a train and coastal shipping fleet.





  • AFIK that’s the way premined currencies work. The “miners” (which are not miners, as you say they just validate the blockchain) are controlled and are not that many

    To be fair I’m not that knowledgeable about XRP and other premined tokens.

    There are transaction fees on cash too, it’s called GST, petrol tax, income tax, etc. This would just make it easier to levy taxes so we can eliminate more onerous taxes

    Oh I get that, I’m all for reducing or removing regressive taxes such as GST in favor of progressive taxes. Dreams are free, but that ain’t going to happen.

    Actually, a digital currency would make it much easier for businesses to collect and report GST. I’ve worked in retail before, it’s a real headache.
