3D Printer Connectors - What's best for in-line connections?

PaulHew

@o_lampe All my printers use Microfit 3.
In the UK I can get them from CPC, Farnell and if I have a big enough order Mouser.

I use DuPont for things like accelerator where it is not a permanent fixture.

Now it's the canal that blocks the ship https://www.youtube.com/watch?v=FESrIXpsQJc

There is a general shortage of electronic components to a point that car manufacturer dropped features or stopped production because they can't get the chips they need.

Did it affected Duet3D in any way?

dc42 also suggested to use the MicroFit 3.0, but I couldn't find a reseller (accepting paypal) with all the required parts in Stock. I guess, the German/EU components-market is empty, due to the well known issues. (and the supercontainership blocking Suez-channel forever)

There appear to be plenty on eBay. https://www.ebay.de/sch/i.html?_nkw=molex+microfit

That's where I was looking. The problem was the crimp connectors for both housings. I'd have had to buy from here and there to scratch everything together.

Hi All,
I've been thinking about these for allowing me to make my printer more modular. A single connection to the radial axis that holds both the radial and extruder motors and all of the hot end connections. That way I could remove it for transportation, assuming I created locating features for easy realignment.

I use an SSR for the hotend heater cartridge so power could be run separately if the connector isn't up to it, although the listing does suggest high power capacity but i haven't found a comprehensive data sheet yet.

Any thoughts?

Those AMP connectors are huge compared to MicroFit. Doesn't matter, if they don't sit in the cable-chain.

Have you tried https://de.farnell.com/search?st=molex microfit ?

@o_lampe yeah they were intended as a single bulkhead connection mounted on the structure of my radial axis assembly.
