      for someone asking what tool to get, it's better to have PA-09 and PA-20 to be able to crimp 99% of the connectors .. then, if same person figures he's doing a lot of type X one can get crimpers for type X specifically, but the universality of pa-09 and pa-20 is IMO unprecedented.

      ...except that for the JST VH pins on Duet 3, it has to be a PA-21.

        Whats the difference between the PA-20 and PA-21?

          PA-09 does 1, 1.4, 1.6 and 1.9mm
          PA-20 does 1.6, 1.9, 2.2 and 2.3mm
          PA-21 does 1.6, 1.9, 2.2 and 2.5mm

            And I take it the duet 3 JST VH requires the 2.5mm crimp capability?

              It's more in the shape of the jaws than the sizes. The PA21 is designed to handle the longer flanges of the VH crimps that grip the insulation.

                Could I get away with the PA-20?

                  If its just the width of the jaws, you can get away with doing each section in to passes, but its also tricky to partially crimp back and forth to avoid sheering off the wings. for a one or four off I'd try it before ordering the new tool. IWISS also makes several versions, all have greater ranges than the Engineer tools.

                  On the other hand, if you're in the UK and have money to spend on a universal tool this would be my choice. https://precisehandtools.com/en/crimpingtools/153-pad-02-precision-crimping-tool-kit-interchangeable-dies-hard-case-4989833035396.html

                    Considering we have 3d printers I guess nobody has successfully produced a 3d printed crimping tool?! 😂

                      For the VH connectors on Duet 3, I don't think so

                        ha, so for Duet3 you are not using the same connectors, here pins have that extra-long flaps that need to curl on themselves before they grip the insulating part of the wire? damn, I need to purchase PA-21 too 😄 ...

                        why the change ?

                        @droftarts it's not only the width, pa-21 is, according to engineer video, different (do not have one so can't say how they work except from videos) as they can handle those extra long flaps, they curl flaps on itself and press the wire, do not curl half circle and embed in wire like the PA-09 and PA-20 .. at least that's how I understood engineer videos when I ordered mine PA-09 and PA-20

                        @jay_s_uk I did number of those "long flaps" pins with PA-20 and it holds the wire good but looks tad ugly and tends to bend the back of the pin a bit so it can be harder to push pin into connector... you can stop pressing bit earlier and that helps if you can train your hand.. I did maybe 50 such pins total in my life so don't have too much experience with them but PA-20 got the job done, not ideally but..

                          On Duet 3, bigger connectors are used because of the higher current capability of the other components.

                            interesting, just checked, you are using drivers that can handle 4A on the duet3 so 3A connectors that are on duet2 will not work 🙂 makes sense ...

                            I have my internal policy that I never use connectors when I need more than 3A and I go with screw terminals but I understand how that could be impractical for the duet ... what are the exact connectors you are using? any chance you can share a supplier code (digikey, farnell, mouser...)

                              @smece You need Tony or David to answer those questions - I'm not part of the Duet team - just an end user like you.

                                  Klein makes excellent wire strippers. Best I've ever used. Gotta strip before you crimp.
                                  And I second the 'right tool for the right job' sentiment. especially regarding crimpers.
