Crimping tool?

This one work really well

thats the engineer-pa20. it will also work. but you wont be able to crimp the connectors used for the stepper motor plugs.

Refering to the JST PH 2.00mm connection found on most steppers these days?

Another vote for the PA-09

This is the exact correct tool to use for one of the pins specified in documentation according to the manufacturer.

With crimp pin terminals, there will usually be one specific tool that is meant to be used with the pins. In most cases, actually, the hand-held tools are only meant for repair and prototyping and the "real authorized" tool is a huge pneumatic machine.

In any event, you can often use a generalized crimp tool labeled to crimp D-Sub terminals, or suitable replicas of such. Be sure to test the tool with each crimp/wire combo to ensure that you're reliably making the connection. You should be able to pull the crimp pin while holding the wire, and the wire should break. If the wire simply slips out of the crimp pin you have not made a secure connection. This test must be performed without crimping the secondary part onto the insulation -- only the conductor portion of the crimp should be used when performing the pull test.

Can you 100% say that it makes a £300 better job than the others that have been listed? Me no think so...

bot

No, but the question was which tool is the exact correct tool, and the answer is the one I linked to.

A Former User

LOL. Can't fault that

@bot, holy crap, $400.

Veti

yeah most of the molex tools are really expensive.

A Former User

All of the name brand tools are expensive, but you will do just fine with a $40 tool (I.e. the Engineer PA-09) and some practice, or even the $20 Chinese IWISS clone for that matter.

Half way down this page you'll see some illustrations showing you how to adjust your crimping for good results, after a while you'll get a pretty good feel for it, visual inspection is a good indicator and you could always try pulling on the wires and see if the wire breaks or if it slips out of the terminal till you get the hang of it.

Was hoping to find another link that had more of a poster format with more or less the same pictures, but, apparently not today.

@bearer very cool

percar

This crimper is a full cycle style printer and works very well

I am getting very good results with this crimper https://www.amazon.com/s?k=B078WNZ9FW

It's handle is more comfortable and was able to get better crimps than with Engineer's PA-09/20/21.

@zapta I'll check it out!

@gnydick, I am using the 1.3 slot for crimping the conductor and 1.9 slot for crimping the insulation.

Before you insert the two wings into a slot to crimp, use the tip of the tool to press the wings to become parallel.

One advantage over the Engineer is that when you crimp the conductors, at one point the two wings collapse at once which makes a satisfying click that indicates that you are done. With the Engineer the crimping was more gradual, the more you press the tighter it crimps. (this is my experience, YMMV)

gnydick

@zapta thank you!

A Former User

The gradual crimping by the Engineer tool is what makes it so much more flexible, it can give you a good crimp for almost any wire size with some practice.

Hello,

I’ve ordered this crimping tools, the set come with 11 head, for my JST needed: http://s.aliexpress.com/3eu6rY3E

Is this kind of tool also works with Duet’s Molex kk or I’ve to get specific one?

Thanks,
Cookie

That crimping tool looks very versatile if you get the multi-jaw kit, however the jaws for JST or Molex crimp terminals are the SN-2 which it says cover 13 to 23AWG. It's not uncommon to use 26AWG, and some devices are supplied with 28AWG wires.

A popular ratchet crimping tool for Molex connectors is HT225D which is readily available in many countries. it will probably work on JST connectors too, but it doesn't do ferrules.

I have one of those, and while nice, I find it far too bulky to allow you to make decent crimps on smaller gauge wire you end up not being able to control the bulk and cant see what you are doing very well.
