Crimping tool molex/ferrules

[pedromelim]

From my search, i understand i would need 2 tools for the different pins, but does anyone know about a crimping tool that would work for both ferrules and the molex kk that come with the duet 2 maestro?
Want to avoid having 2 tools if there is 1 that could work for both.

They are very different types of connection. You can probably get die sets which would allow one handle to be used, but this is usually the more expensive option.

You can get a tool that will crimp many types of open barrel terminals like molex kk and similar, but I haven't seen one that does that type of terminals and ferrules as well.

The open barrel terminals are quite picky and needs the right die size for the right terminal, while the ferrules are generally one tool from 0.25mm^2 to 6mm^2 or thereabouts.

Which connections do you need ferrules for? Could you use spade terminals with open barrels instead?

You can technically buy one ratcheting crimper, and two dies, one die for the molex, one die for the ferrules

This page will show you several, you don't have to buy from them, you can get them very cheap from Amazon

For building a 3D printer, you're going to need the dies for

• insulated terminals, the fork kind used for PSUs, or uninsulated if you use heatshrink
• ferrules, for the terminal blocks on the Duet
• open barrel, these work for the Molex/JST/Dupont types, so these will work for the fan/endstop/motor connectors, as well as any E3D/Prusa parts

Having one ratcheting crimper per die will make your life so much better since swapping dies is a pain

For the small connectors I had good result with this crimper https://www.amazon.com/gp/product/B078WNZ9FW

Similar to the Engineer models (e.g. PA-20), you crimp in two steps, first the conductor and then the insulation.

I used this for both - works way better than my other cheap crimp tools:

(You can also get it on amazon,ebay, aliexpress)

You can still get open barrel type fork terminals, and purely U shaped terminals to crimp on bare wire.

Other than that as the other say, you can have different dies in one tool, but you'll wish you had one tool for each and its generally not cheaper.
