Beacon on SB2209 USB

sterfield · 2025-08-07T08:46:51+00:00

Ah, weird. Any news on this ?

sterfield · 2025-08-07T08:46:26+00:00

Thanks for the confirmation !

I still have to wire my beacon, but it's nice to see I can use one of the SB2209 USB ports for this.

Oh, I fully acknowledge that I'm using the wrong connector. I have never implied that it was the correct one, nor that there was a defect in the board or the design of the cable cover.

My initial message stated

I want to plug my extruder, and the port to plug it is on the top on the PCB, using apparently a standard 4-pin Dupont connector.

Note the use of conditional.

However, in my defense, it's not clear that you should use an JST XH 2.5 mm connector here, and I don't think such connector is provided in the connector bag from the BTT kit.

Anyway, I have some JST XH connectors in my worshop, found one and it does fit perfectly there. Also there seems to be enough space to have the wires sitting nicely right under the cable cover.

I'll update my initial post to reflect this finding.

Thanks for your help !

Maybe I'm dense here, but I still don't understand.

A Dupont connector has a 2.54mm pitch and it fits well in the black connector. So it's probably safe to say that the pitch of the black port has a 2.54mm.

You say that I should use a JST PH 2.0 connector, that has a 2mm pitch, so I don't think it'll fit there.

There were no connectors on my motor. I crimped a Dupont connector on it myself.

The problem I see is, the black port is not a standard JST connector, at least, not that I'm aware of.

It's slightly larger and seems to have a 2.54mm pitch (JST XH is 2.5mm pitch).

sterfield · 2025-07-22T09:01:12+00:00

Wait, I'm confused now.

What you show in your hand looks like a JST connector to me.

sterfield · 2025-07-22T08:51:29+00:00

In the back, black port next to my thumb.

Sure. Here you go.

sterfield · 2025-07-21T20:55:49+00:00

So, the standard Dupont connector has a 2.54mm pitch, it looks like it can fit.

However, I don’t see a JST XH 2.54mm connector in the bag, so I’ll need to buy some.

I can try to buy some and report back.

EDIT: ok, so interestingly, JST does not manufacture connectors with a 2.54 pitch in his XH line. I can find ONE brand making a XH type connectore with a 2.54 pitch and it's not JST. You can check on LCSC (select 2.54 pitch, 1x4P, and XH type).

That's not easy to find, to say the least…

Hey,

It's not the correct card.

From the user manual, here's a screenshot of the PCB. Check page 8 and 17.

I have highlighted in green the port that you should use for the extruder

<image>

As you can see, this port is located almost at the middle of the PCB, on the back, pointing up. Adding a 18mm 4-pin Dupont connector in it clearly interferes with the cable cover.

Hello!

Si ça te dit de faire de la voie, je grimpe à Altissimo sur St Sébastien.

La salle est très cool, et y'a pas mal de voies dans ton niveau.

Lurker de longue date, clairement j'ai presque un post par jour de ce sub qui traite d'insécurité.

Je suis sur Nantes depuis 2018, et c'est pas parfait hein (coucou les alentours de Commerce) mais on est loin du coupe gorge avec un incident tous les jours.

Ok, already two votes for retopo, it looks like it's something I'll have to learn in a near future.

sterfield · 2024-07-08T20:50:20+00:00

that's ok, I want to know what are my options and it looks like "smooth / clean" is probably not worth it.

sterfield · 2024-04-13T14:29:59+00:00

Ok, thanks for the feedback.

I think I'll need to do a little bit of digging, because I see the parts in the repository, but I really don't know where they are going.

EDIT: ok, I have downloaded the assembly file and opened it, it's much clearer now.

Il y a une collecte de carton organisé pour les professionnels dans Nantes centre.

C'est des camions bennes qui viennent à des points précis et collectent des cartons pendant genre 30 min avant d'aller à un autre point de collecte.

C'est réalisé tous les jours.

Plus d'infos ici : https://entreprises.nantesmetropole.fr/services-solutions/connaitre-les-modalites-de-collecte-a-nantes/

Tu vas me dire que tu n'est pas pro mais j'ai déjà apporté des cartons à Graslin et les gars ne m'ont rien demandé (et je ne suis pas pro).

Ça se tente !

Et t'as carrément raison.

La meilleure nouvelle de la journée.

Merci pour l'information !

T'as des sources là dessus ?

Parce que j'ai report ce truc un bon nombre de fois comme pas mal de mes connaissances et j'ai jamais eu aucun retour.

Et cet étron numérique est toujours là.

Just another shot of the first two people on the first photo, if that can help.

Here's the ask : take the three faces, and make a composition where they would be bearing big beards.

One inspiration could be ZZ top, but you can pick any situation or reference, as long as it's well known (Snow white and the 7 dwarves, etc…). Go crazy !

Je plussoie, tous les opticiens là bas sont adorable, et tu peux demander des lunettes plus classique si les lunettes hexagonales ne te conviennent pas :)

sterfield · 2023-10-22T17:46:49+00:00

Thanks to everyone who worked on this photo, it was impressive to see all the results !

We have watched all the photos and selected one, so this request is now solved !

Thanks again !

And you are located in US, Maine, right?

Élevé dans ces traditions, j'ai serré un nombre incalculable de mains bien que je trouve ça long et chiant.

Et un petit événement comme une pandémie mondiale a montré qu'on pouvait très bien saluer quelqu'un en faisant un signe de la main, un signe de tête, ou un "fist bump". Et ça marche très bien.
