Which crimping tool for smart effector
-
I use a very cheap, "Chinese clone" crimper, with several different width slots.
This does require me to do 4 operations: Two on the "bare wire" crimp wings, and two on the "folds over onto insulation to provide strain relief".
While this is a tiny bit of a hassle, it actually produces better crimps than anything else I've tried, including some very expensive tools that are supposed to match these connectors.
Keep in mind that expensive crimpers are as much about "total throughput speed" and "relatively unskilled labor" for an "acceptable" crimpas they are about producing a perfect crimp.
Sorry, I don't have a specific link.

@danal thanks Danal. Do you know what the connectors are supplied with the smart effectors. That might help me buy one that at least should be up to the job? thanks

they are molex KK for the 8 way and Molex Microfit 3 for all the others now. I use a jst crimper from Hobbyking which is cheap and just works (once you get the knack of it)

@dougal1957 I bought this, fingers crossed it works

Now to work my way through the 100page thread that somebody else started about upgrading the Anycubic linear plus to Duet Wifi!
I just really hope I don't ram the smart effector straight down into the build plate during setup. Would be a shame to break it!
Thanks

I use this tool for crimping AMP, Amphenol pins, JST, and all of the Escher3D products' pins..DUET controller, Smart Effector and PanelDUE pins.

@sparkymark79 I have the same ones (PA-20) and they work great, I initially got the generic JST style crimper and failed miserably and making good crimps.

i have been a component level engineer for over 30 years. I have dozens of diffrent crimpers... i luv having the exact right the tool for the job and all but to date best crimping results i have gotten was with a 99 cent pair or tiny needle nose. If you have the patience for it. still a good way to go IMHO

For low-volume repair work, high-quality ratcheting crimp tools are what is used in industry. Here is a cheap version on ebay: https://www.amazon.com/IWISS-Professional-Compression-Ratcheting-Wire-electrode/dp/B00OMM4YUY
Non-ratcheting types such as the one posted above are, in my experience, horrendous and are not used in industry.

Ahh... the cheapies I use are PA21
They are "too thin" to properly crimp both sets of wings on the connector. Which I exploit to crimp each set manually. Produces GREAT results, very slowly, which is why you'll never see them in a shop. Still, great for hobbyist.
-
Hmmm... they are not quite a cheap as I remembered, about $40 to $45 through several channels. I guess I'm remembering "cheap when compared to $300" or whatever.
Anyway, these work REALLY well for me, on a very broad variety of connectors:

I will soon purchase one of the Engineer Crimping tools but I still haven't decided between PA-20 and PA-21. I have no idea whether there is a use in the small difference between 1.9mm and 2.0mm that PA-20 has compared to a more evenly spread selection of widths and going up a little larger of PA-21. Any advice on this? I will mainly crimp connectors for the Duet.
-
@danal Thanks a lot for your information. I have no success with special crimp tools so far, the wires always slip away after the crimping ;-( and this is very frustrating. I'll try your manual method now, with a cheap tool.
-
I use this type:
https://www.amazon.co.uk/Ratchet-Action-0-08-0-5mm²-Adjustable-Connectors-Ratcheting/dp/B0769H3NWPNot exactly this one as i cant find the no name brand one I bought last time.
-
@t3p3tony Thank you for the link. I soldered everything 30 years ago, but today's state of the art seems to be crimping because soldering loosens with time.
-
I linked one above that works extremely well and is not expensive at all I recommended it to a NZ Guy in another forum and he got one very quickly and fed back that it was excellent as well here it is again Crimps

Saw this the other day and found it interesting.

@dougal1957 Thank you, I'll try it. I have JST-XH instead of JST-SH, I hope there is not a lot of difference.
-
@t3p3tony Dear Tony, I tried your crimp tool, it works quite good for those very small crimps, thank you!

In finally decided to order the Engineer PA-20 as already bought by @sparkymark79 and for comparison also ordered the IWISS ratcheting crimp tool recommended by @bot. I only read very positive about both of them but I have to admit I immediately fell in love with the manual tool by Engineer. It produces great crimps and even though it will require two actions to perform I was not really slower as with the ratcheting one.
So PA-20 it is for me. Now I just need more stuff to crimp.
Thanks also from me for all your feedback on this topic. It was very interesting to see all the different opinions especially on the really cheap tools.

@wilriker glad to hear you found a tool you like! Remember to check the crimps to ensure they're good -- you should be able to pull as hard as you can on the wire and it will not move at all from the crimp. I hope your hands don't get too tired after many crimps! Perhaps one or two is easy with the manual set, but after doing 20-60 pins, it can get tiresome.
