To be fair, it is four plates (3 mobile plates, 1 base plate), but it's still not any less confusing for customers.

*implies*

Yeah. Same here. For 80 bucks I'll probably make my own.

I'm sure all that bad injection molding tooling cost them a fair bit of money!

@@Alex-nl5cy It was probably molded properly but not cooled properly, or as you said bad molds if you wanna push 'em fast through the factory, being that the case the price should drop even further.

Maybe in a few weeks on aliexpress

Maybe they shouldn't have spent so much of the project budget on patent attorneys and applications

Honestly I'd just get out your calipers and reverse engineer it a little to fit, maybe offer a bracket

They launched the mutant v2, maybe it's the answer u want

@TheHighRishMan if you pay a lawyer, the patent office thinks you deserve one

@TheHighRishMan You don't even know what socialism is. You probably never read the wikipedia articles on socialism and communism, now did you?

@@natalieisagirlnow Not true. The first thing the USPTO will tell you is “No!”, whether with or without an attorney. I imagine other patent authorities would do the same as an applicant is asking for offensive rights by the patent authority. This firm may just be paying the small entity fee to thwart any attempting to copy it for a while, knowing they won’t get the patent in the first place. First rejection letter is about 9-months, outside of COVID-19 office work protocols. If indeed another prior art similar in the field of FDM was made, I’d say their few boastful claims will be laughed out of Washington, D.C. as many flat-earth free-energy space ships do as well.

There's different types of patents. They probably can patent layout or aspects of its structure.

@@GENcELL2014 If there’s a FOSS design that’s publicly released, then a utility patent application is void. Software patents only hold in USA, but I cannot see why they’d have such nor why. Then there’s the design patent to which they might be able to get one by designing a specific way, but in this application such a patent would be wholly useless. I worked in intellectual property as an engineer and alongside attorneys.

It's ok because the chinese players in the 3D printing space simply don't care, its practically impossible to enforce patents in the far east. And before you say it, no western countries will not prevent the import of the patent violating goods because, you guessed it, its too much effort. Patents are pretty ineffective in the global market, all it does it hamper western companies, pretty sad.

@@mawoodmain if you argue like that, why do they make the patent in the first place? according to you they could also leave it away and like that everyone would be happy.

@@certified-forklifter depends if you care about Western competition as patents will stop them. But if you think a patent will secure your product against being cloned and sold at half the price on AliExpress you're mistaken.

@@mawoodmain well, Xchange released they product first.

@@certified-forklifter the patent system is first to file not first to invent or first to market.

There’s tons of prior art for this on thingiverse. You can claim patent pending if you have submitted a patent, but I doubt they will be awarded it.

Could be on the pin arrangement for wiring harness simplification. Though again, probably prior art out there invalidating it

@@goeland86 Yeh, this reminds me of old Pentium 4 ZIF sockets

Probably for using a dove tail for the tool head exchanger and also a locking a realeasing lever on the tool head exchanger and maybe even for the electrical connector on a tool head exchanger. Idealy the patend will not be granted but if it is it could block a lot of better developments. So regarding that their product has a lot of issues ( connector undersized (= another fire hazard), hole patern matching to nothing) I would strongly disadvertice from buying this and thus supporting their patent. Just as a reminder to everybody: the whole point that now we can all play with 3D printers is because an older patent ran out. Else I would have played with them allready in the 90th (then we just build little mills in school driven by parralel port). So more blocking patent (and even from substandard products) is just what we need :(

The dovetail is a cheapened version of a quick change tool post for a lathe, they better not get a patent.

Yeah, really seems like it should be pogo pins or something similar.

@@_Piers_ maybe these are specifically designed for a high amount of mating cycles. They do appear to be high quality. I would be interested to hear from the manufacturer on this.

I think a board edge connector would work better. I'm thinking like how old Super Nintendo work. Those connector handled hundreds to thousands of connections

I've seen similar connectors rated for 200 cycles, so that sounds reasonable. Probably enough if you only swap occasionally to a larger nozzle etc. Board-edge isn't always better, though, for example PCIe is only rated for 50 cycles.

@@MadeWithLayers yeah it probably will be fine for a lot of people my only real concern is the fact that some of these pins are going to be carrying high current. If they loosen up they're going to go high resistance and that's going to cause a lot of heat.

What do you mean? Why is patent pending bad?

@@dawn9340 It doesn't seem to be a particularly revolutionary idea to add a row of connectors and a latch, however if the patent is approved open-source projects would not be able to have similar designs for several decades. So in this case yes.

I understand now. If it’s pending they submitted it and is already protected. Unless it’s shot down they can litigate I believe currently.

There are a lot of examples where the patented technology is not very innovative, that is the solution is very obvious. Nevertheless the patent was granted forcing everyone in the field to to either workaround this or pay fees to the patent holder.

Exactly what I thought ! Not going to buy / recommend anything from this company.

I have about 10 sets of your ExoSlides on a custom machine I built. Will see if XChange will mount to it.

THIS. i really wish e3d did that. a threadless collar style heatbreak?

@@ameliabuns4058 The heartbreak used by E3D's multi-extrusion hotends (Kraken, Chimera) is actually smooth on the outside, so you can more easily vertically align multiple nozzles. If only that was the case for the V6, Hemera, etc...

Use a wrench to change the nozzle man !

@@whatisyouremailid of course but it would be so much easier to swap out hotends different nozzle sizes. I hate messing with nozzles.

Just for humor :-)

You may have a point about patents holding innovations back (although I think that point is at least debatable.) However, I cannot see how copyrights (even long lasting copyrights) are holding creators back. For example, Harry Potter is copyrighted, but any author is free to write books about a child going to a school for wizards. You just can't call that child Harry Potter.

Everything you've said is a Big Corp myth. Patents spur innovation - why do you think the US is ahead of the pirating Chinese? There's also no recourse for a small patent holder to sue for infringement, so the deep pockets big companies do what they want, stealing patents/ideas...it's the "trolls" that buy the patents from the small inventor and go after the big dogs, leaving the big companies with an inability to walk all over small inventor innovation (which costs a LOT of money). That is why the lobby is so strong for "reform" and why suckers parrot the demonizing of organizations that pay the small inventor for his/her investment in the patent they hold.

Should fit the X1, but I'm not a huge fan of the X1 to start with

check proper printing's videos about his quick change system

@@kauppinen6487 just saw it, last video on it was in may (where he made just a connector)

@@Netherlands031 we can treat this video as the required features list

E-Steps can be set via gcode (M92)! reprap.org/wiki/G-code#M92:_Set_axis_steps_per_unit

E steps can be changed with gcode, so you could presumably have a tool change gcode file to run for each toolhead that sets the correct E-steps/PID/nozzle offset/whatever else needs to be changed.

I was thinking the same thing, I bought an 0.2mm nozzle a long time ago but haven't got round to trying it because of the hassle of swapping it out and the worry of ruining the heatbreak.

Yeah, swapping nozzles on the v6, especially when its mounts lets it rotate (like in the Prusa machines) is not something that's enjoyable on a regular basis.

I'm pretty sure everything that could ever be invented in the 3D printing space has already been discussed on the RepRap forum 😉

Yes. Totally wrong approach to increase your audience. And: "only 23% of you are subscribed". I am an individual and might have good reasons to not be subscribed, I don't like to be treated as just a number in a statistic.

Watch the newest ThisOldTony video, there he proposed a nice different idea for that

This and also sharing print heads between printers is one of the reasons I love this design approach. There were several things I didn't like about my Lulzbot but their changeable tool heads were great to work with.

This Old Tony mentioned this problem in his latest video too - COINCIDENCE? I THINK NOT! (Ah, I see @Tarek Knanneh beat me to it)

It might be kickstarter but I actually like the look of the xchange more...

That would be my use case.... Dont see switching while powered up.

It´s a Flir One Pro go.toms3d.org/flir

And im very new this the 1st printer and 1st time I've ever seen one in person

And if not will the hemera extruder work with tronxy sorry im such a noob
