After the large external E-mod, now a small compact version.

#

The first external E-Mod, the new one is way smaller

That looks interesting but damn its big :D

#

got some pictures from inside the enclosure for us?

The first version is now a bit too big for me. That's why I came up with the idea of designing a version that is completely printed and smaller. Backpack because I wanted to put it behind the printer first. In the meantime, however, I have come to the decision to construct a desktop stand and the option of installing the backpack on the side or above the printer. At the moment everything is still under development and I'm still waiting for parts. However, I may print some or all of the first parts in the near future. I'll keep you up to date. The backpack is designed so that an Octopus or a Manat board can be installed there. Now there are a few pictures.

Yeah, that is the old one 😅, see text below your comment

cable protection added

that looks a lot more compact!

#

would also be compact enough to mount it on the back of the printer so that its no in the way?

I don't know how big a 250 is, but with a 300 and 350 it's definitely the right size. I have also provided a picture with dimensions.

Okay, it worked but the screws were too long 😅

Next step: Adjust the orientation so that the beautiful side can be seen from the outside

Yay first package with the 25x0.5 control cable 😅

I still have to make a few test prints and then fine-tune the material I want to use. The 24-pin CnLinko will arrive between February 11 and 18, and once they are there I will compare them with the CAD data again. I continue to use the 770-713 plug from Wago to supply the bed. A CnLinko 3 pin would also fit, but I have the Wago and it's cheaper 😅. If anyone would like a board with CnLinko 3 pin, just let me know.

Some pictures with possible positions. The aim is to have as many identical parts as possible for different mounting positions. For size comparison, this is a V2.4 250 mm.

Love the strap-on idea!! 😂

#

Kidding aside...the cabling system here is awesome! This makes reconfiguring your machine so much easier by having the electronics and printer frame as separete entities. And we ALL know these machines don't stay in one config for long! It just makes sense.

An idea of how the Bachpack can be installed

#

#

I'll wait until I have all the parts. Then I'll continue when I've built the first backpack.

I give up, soldering the plugs sucks. Maybe I don't have the skill. But there are 19 pin plugs with cable, then you "only" have to solder the sockets. I go back to ATX or Micro Fit connectors.

#

Then I'll get to work in the next few days and create a model for ATX/ Micro Fit connectors

restive spindle Mar 1, 2025, 2:55 AM

#

Damn. Too bad they don't use pins vice solder cups. Amphenol connectors do, BUT they're insanely expensive. What about phoenix connectors?

#

oak gull Mar 2, 2025, 3:51 PM

I made it after all, somehow I'm always annoyed by something like that and I carry on anyway.

Is there a compact version with 20 to 24 pins?

oak gull Is there a compact version with 20 to 24 pins?

I filtered down their product range by 2.54mm pitch connections and found that that pitch maxes out at 24 pin positions, so yeah 👍

Nice! After all the pains in the ass, would you say this checks the box? I had to put this project on the side burner because of work and other things, but man I still love this idea!

The CN Linko plugs are great. But if I had found the 19 pin version with cable first, I would have bought it and just soldered the sockets

#

I still have to solder the second pair. At the same time, I'm trying to optimize my printer in terms of tolerances. I'm currently at around +/- 0.2 mm and I'll see if I can leave it that way.

#

I'm also just working my way forward bit by bit, as I have time.

oak gull Mar 3, 2025, 6:47 PM

When it works, it can even be relaxing 😅

First test assembly and the cover panel is currently being printed

The printer fiddled around and then ran out of filament, but this is what it looks like now

Forget to think about the tolerances 😖

Everything looks good, now I just need a quiet minute to rebuild everything. I'm also thinking about converting everything back to the JST, with a box to throw the cables into so it's a bit more plug and play and you don't need all the Wagos. Maybe I'll even do that before I convert it 😅

Now I'm making a distribution box for the printer after all. The advantage is that you can simply continue to use the crimped plugs. Here is the first sketch of how the plugs should be arranged.
