Euclid probe kit with hardware in EU?

29mins in and he had put the magnets on the wrong side.....

It's a live video so a significant social aspect (vs informative).

We should have similar videos for the Duet/RRF where dc42 edits config files with live user comments and donations.

@paulhew magnets here too! Can you PM me?

@sinned6915 the biggest problem is sadly the magnets in Europe....;(

@sinned6915 so you are saying it's against the license to give away the probe for free? That's an interesting interpretation of the CC-BY-NC-SA and proves once again that it's important to stick with OSI approved open source licenses that guarantee the four freedoms.

I guess I'll stay away from the Euclid probe then because you're basically saying I couldn't sell or give away for free a printer with the Euclid probe fitted on to it.

Hmm

@pcr doesn't matter, that could be under another direct agreement with sinned -- I am just reacting to what they wrote above.

@oliof, since it's not a patent, a new pcb design should address the copyright issue.

I am happy with the Clicky design which is simpler and pcb-less.

oliof

@zapta depends on whether sinned would go after people claiming it'd be a derivative. The idea is poisoned for iteration by third parties, and there's not much to do about it.

Also, klicky probe is GPL 3.0 but references Euclid and Quickdraw as inspirations, which has an even worse license from an Open Source point of view. If we're lucky, this will never be lawyered out, but if even giving away probes for free is considered "not in spirit with the license" then I am not optimistic.

I think the only way this idea is salvagable for Open Source usage if there's a similar design that's prior art and properly licensed.

Copyright protect the specific expression (e.g. documentation, PCB layout, etc) but not the method (a stow away electro mechanical probe), structure (a pcb with two magnets and a connector), dimensions (distance between magnets) or functional aspects.

BTW, @sinned6915, did you come up with the idea of a stow away probe with an electromechanical switch and conduction through a magnetic coupler or is it based on previous works?

@zapta I am not claiming they'd be justified to go after anyone, given their hard stance on people wanting to give away the probes for free (which I personally don't believe is enforceable btw) may mean they'd still give it a go.

@oliof No sorry that's not what I meant.

I've been looking to have this made and sold in the EU, and have had to deal with some vendors I approached basically threatening me with "This is the deal we'll offer, and if you don't take it we'll make our own and make sure you can't sell your design in the EU"

I'm sorry for letting that affect my response, the design is very much still CC-BY-NC-SA.

I came up with this on my own and cited it in the readme on gihub. It evolved from the semi-automatic probe and the steel frame of the Wanhao i3.

yes, we have found that out the hard way. we are working on remedying that.

@Gixxerfast I now sell the official kits from @sinned6915 in the UK

@jay_s_uk, for voron v2.4, does the Euclid requires having the Z stop? In other words, can it be mounted in such a way that it can be used for Z homing as well, similar to the Klicky?

Gixxerfast

@zapta OK, I'm not Jay (obviously ) but I can answer that question, yes you can:

jay_s_uk

@zapta I don't see a reason why it can't be used without a z endstop. examples are given here for picking up the probe when the Z dimension is unknown.

and thanks @Gixxerfast

zapta

Thanks @gixxerfast, this is very useful. Where can I find the STL models?

@jay_s_uk, the examples I saw had the Euclid hanging on the main frame which requires previously homed Z to pick it up. @Gixxerfast's pixures shows how it can be mounted on the gantry.

BTW, when in parking position, is it held securely in place, e.g. if the printer is tilted on its side for maintenance work?

https://github.com/nionio6915/Euclid_Probe/tree/main/stls/Voron

Think (probably) I used VoronGantryMount2_Bkt.stl and VoronGantryMount2NativeCarriage.stl

They could be optimized further but works fine as is for me.
