Topic: Solidoodle Hot End Connectors

Can somebody tell me the exact type of the hot end connectors and where to buy them? I found another thread about it, but it didn't specify the exact model. I just want to make sure I get the right one....
(Talking about the blue and red connector as seen in the picture)

Re: Solidoodle Hot End Connectors

I saw this link, but which one is it (model #)? Not sure of the wire size... also the blue connector seems to be different from the ones listed.

Re: Solidoodle Hot End Connectors

Also, A31080-ND, A31107-ND, A1906-ND  (plus a few more) all have the same description. Are they the same (some of them are priced differently)? Just want to make sure I get the right ones.

Re: Solidoodle Hot End Connectors

In my experience, those connectors are pretty useless without the proper crimping tool (at least, I couldn't find a way to crimp them by hand). I suggest replacing everything with JST. It was a bit painful but it worked in the end.

Once again have to quote:

They are right there under the TE ones... and available from any Hobby/RC store or electronic components place (ala radioshack).

My point in replying as I did was to share that the information you sought was already provided - both on the Wiki to begin with, and then right here in thread... I'm sure you appreciate that it gets kinda dull when the same questions are asked when the info has already been provided in the very thread and all that people needed to do is read that info or maybe employ a tiny bit of google-foo.....

At least I didn't just reply with a Let-me-google-that-for-you link...... Its amazing how much can be answered just by checking either of the two Wiki's - and no need to wait for someone to respond on the forum ! Instant Gratification FTW! smile smile

I aint on here as often as i used to be,, but when I am, I've noticed there has been a bit of this lately.

I would say I generally am, I just don't beat around the bush about things and usually tell it how it is... Apologies if my statement appeared confronting to you - it was not a specific intent.

Re: Solidoodle Hot End Connectors

But which connector is it the correct one (not the JST)? Still haven't found the answer. Also, the blue connector doesn't appear on that page (the one on the page looks similar but isn't exactly the same).

confronting isn't the word I 'd have used, but it really is no problem.....THIS TIME! smile

Sorry for not replying earlier, I forgot to click the "subscribe" button!

I don't have the connectors at hand, but I found two better searches on the digikey site:
Red connector (22AWG): http://www.digikey.com/scripts/dksearch … ageSize=25

Blue connector (26AWG): http://www.digikey.com/scripts/dksearch … ageSize=25

I am sure that from there, you will find the exact models. If you do, please write it on the wiki!

Re: Solidoodle Hot End Connectors

Apparently the JST connectors are also referred to as BEC connectors. I just picked up a couple of pairs at the hobby store. My extruder temps started wandering up and down randomly. I swapped extruders and it was OK for a day or so, then the same thing time to upgrade. I ordered an additional package of ten pairs from Amazon for 8 bucks. You can see them here:

http://www.amazon.com/JST-Connectors-Au … bec+female

I'm off to solder them on.  The thermisters and resisters aren't polarized, so I don't have to worry about that. I figure I'll make the heater male and the thermister female on the extruder and vice versa on the printer wires. That way I wont be tempted to plug things in the wrong way around. ;-)

Re: Solidoodle Hot End Connectors

A BEC is a Battery Eliminator Circuit it is used a lot in RC applications and yeah some of the the BEC's have JST's on them, amazon just puts it in the title as a keyword.

Re: Solidoodle Hot End Connectors

What Ronsii said - the connectors ARE just JST. BEC is the name for a specific Module that mostly carries JST or for higher current work "Deans" Connectors (T-Type) etc .......

Unless you use lead-free solder with its higher melt point, standard leaded solder is not wise to use, as the heat from the current and the extruder can cause the heater wires and the thermistor (worse thing to fail) wires to fail open as the solder degrades.

The JST connectors should just be *crimped* on... This is also the reason the stock connectors use a modified punchdown socket and bullet or bootlace crimps.

Solder anywhere near the hotend will just be asking for trouble in 2-3 weeks time... Just ask Lawsy wink

Re: Solidoodle Hot End Connectors

Adrian, thanks for the heads up. I'll keep an eye on it. I did get a good twist on the wires before I soldered them and the connections are at least an inch or more away from the heater.
