Connectors?

[Toddimus]

I got some of these and they seem to work well too:

Also, in addition to including a connectors kit with the boards, it would be really handy if folks that sold the boards also offered bulk packs of the connectors. It would be nice to be able to pick up extras at the same time as ordering boards & other parts.

Hi Ian

If you would like an additional batch of connectors then drop us an email with what you had in mind and we can invoice you (won't be much) so that they go with your order.

I will discuss with Roland about the logistical hassle of adding bulk connector packs as an additional stock item. It would save on delivery but it does add a bit of a picking and packing task for a very low value set.

Cheers

Tony

How about adding "Additional Duet accessory kit" as a stock item?

Thanks, David. Good to know my Digikey foo isn't as bad as I suspected.

I'm sorry, I got a digit wrong, it should have been 22-01-20x5 not 20x4.

Edit: here is the 4-way shell on Digikey: http://www.digikey.com/product-search/en?keywords=22-01-2045

I used these KF2510 connectors from Aliexpress (4-pin, 3-pin, 2-pin)… they are supplied with crimping terminals and exactly the same as Molex KK.

There are cheaper sets, but I can't confirm their quality.

Hello,

What is the male connector reference for the extansion board, i plan to wire my external driver to it but i only find some connector with ribon cable.

Thanks !

If you want the full 50 ways then this one looks suitable to me http://uk.farnell.com/amphenol-fci/65846-012lf/connector-receptacle-50-position/dp/1924648?aa=true&vw=&selectedCategoryId=&categoryId=700000005017&eq=N%3D203442%2B110049686%2B110178988%2B113176173%2B113190048%2B2031%26amp%3BNs%3DP_STORE_MARKETING_RANK_FARNELL_UK%257c0%257c%257cP_MAN_PART_NUM%257c0%26amp%3BNtpc%3D1%26amp%3BNtpr%3D1&searchView=table&iscrfnonsku=false. I have previously used similar connectors with fewer positions to connect wires to the expansion connector.

Some motors and printer kits come with JST XH style connectors. I can tell you that if you use a dremel to sand off the JST XH locking protrusions, and switch which holes the wires are in, the JST XH will fit onto the Molex KK connector.

But, some of you are probably cringing right now. I am too a bit. So, are there connectors you can buy to convert JST XH 2S and 3S to the appropriate Molex KK? I looked a bit and didn't see any.

Sort of a silly issue, since I know the board comes with the pins and connectors, but I just don't trust my crimping ability. I've already sheared the wire in half a couple times. But, while that is annoying, at least you know you did it. It's invisible errors that worry me.

Hello

yes sand off the JST works. thanks
now I get a new crimping tool for jst, molex kk usw….
that looks better.

would be nice to buy finished Molex KK to jst (6-pin) Cables (1m) for Steppers
and 2-pin , 3-pin for other things

[dc42]

You can buy JST to DuPont stepper cables from suppliers such as Robotdigg, and they will fit the Molex KK connectors, with the disadvantage that they are not polarised and don't lock in place. However, the pinouts of JST connectors on stepper motors are not standardised, so you may have to swap pins around in the Dupont shell like I had to.
