    Is there anyone that would mind sharing photos of their Molex Micro-Fit connection setup on their BigBox... Just received my Titan shipment email this morning from E3D. I would like to implement these connectors at the same time that I am going to work on this Titan upgrade.

    That kit looks like really good value! The crimping tool is a good bit cheaper than the official molex one too.

    Yep, those look like the right ones. The Molex part numbers I got were:

    43645-0200 and 43640-0210, 2 way plug and receptacle
    43645-0300 and 43640-0301, 3 way plug and receptacle
    43645-0400 and 43640-0401, 4 way plug and receptacle
    43030-0007 and 43031-0007, M and F crimp pins/sockets


    I have the same ratchet crimpers but I can't remember where I got them from as I've had them for a while, might have been hobbytronics.

    Hiring an electrical engineer to come to your house to crimp on the connectors is cheaper than the official Molex crimping tool! :rolleyes:

    Besides the hot ends, are there other good suggestions of where someone would place the connectors in-line?

    I have them on the Titan Motor mount.... I saw an image here in the forum where one placed them on the top spine... or you could have them in mid air floating
    Yesterday I was really happy to have now unpulgable cabling...

    Depends on "what is right" :D I wanted to show the mess I have with the Titan.
    But if you wanted so see the Plugging part that is not the best view....
    These may be better, note this is work in progress

    That looks good. How is it fastened? Glue?

    It is soldered with a soldering iron with adjustable temp set to 200C :D
    And the cable tie mounts are removed with it too.

    Just a reminder that, in a pinch, you can use big flat PC PSU molex connectors as well for these.
    You can find them in almost any computer hardware shop locally. They're easy to crimp even without a tool (needlenose pliers will do the job).

    They're not convenient for unplugging things often, but you won't be anyway.
    They're wider than microfits (obviously), but thinner, so you can often tuck them somewhere or stick them to the extruder body with doublesided tape.

    @orcinus I think the ATX connector are too Molex but not the Micro Fit, just next bigger version.
    And you are right needlnose pliers will do the job even for the Micro Fit 3.0, especially if you have a crimping tool but just do not find it :(

    Yup, those are Molex connectors as well. Didn't mention it except in the first line to make the sentences less confusing/confused (”besides ordering Molex you can also use locally available Molex” :D).

    Just ordered a bunch of Micro-Fit 3.0 connectors and pins.

    Will probably not use them until I get to try out a dual Titan and thats still some time in the future as I have not ordered any titans yet.

    First I hopes I could have bog connector at top and pushing connecting multiple 4 pin ones into the bigger one for modularity. But after studying the pics it looks like they have protected themselves against mixing sizes.

    My plans are as follows (I have dual):
    1. 4 pin connector for both thermistor and heating cartridge as I will not remove them from the heatblock. This makes it possible to change out the whole heat block between regular and Vulcan with a single plug.
    2. 4 pin connector for both fans, heat sink and nozzle fan.
    3. 6 pin connector for IR bed sensor and X end stop
    4. Maybe I will use a 10 pin connector for point 2 and 3 instead. I'll have to see what fits best.
    I did some googling how to extract a pin after it's been pushed in the connector housing. According to Molex the pin should be discarded as the locking fins are bent. Anyone tried this?
