Hi and thank you for your work.

I am wondering if PLA is suitable for this case? I am not sure about what temperature the motherboard raise usually.
Maybe ABS is preferable ?

Do you have any feedback about which material should be used ?

Thanks

There are double PCIe link(x1 Lane 15) between P52 M.2 wlan/bt slot and APU on page 1. I think one should be USB 2.0, but you've forget to edit after copy-paste.

Please release schematic and Boardview to allow DIY repairs and mods

I'm currently about half way through printing the bottom left portion of the case and have just noticed that the case will be about 0.1mm off dimension because I printed it at 0.2mm layer heights and the height of the model 12.5mm. To be clear, this isn't a huge concern given the general inaccuracies of 3D printing and the small difference but it would've been nice to know ahead of time that I could've printed it at 0.3mm layer heights and saved about 2 hours of print time.

It would be nice to have the suggested print settings in the README so that there's no guess work involved. Something like this should suffice:

This way, we have a simple enough baseline to go off of so that we can further tweak the print settings or just use one of the many print profiles that slicers include these days.

I have to say that I don't like these tiny arrow keys, even if the shift key on the right is missed, it's better than two tiny arrow keys right here.
Does anyone use the shift key on the right?

It'd be quite helpful to have high-res pictures of the mainboard. There's gotta be some already available, that were used to create pictures in this listing. Such pictures are useful for research, mockups, debugging, and questions for doing dev program work. I've already had to refer to the product page for the mainboard a few times, while researching the motherboard features, but the picture in the listing is way too low-res.

I've been working on a project where I need to interface with the eDP connector on the Framework mainboard. I just recently got a working board spun up and when I connected it to the mainboard I was seeing +17.6VB_INVPWR hard shorted to ground. I did a little bit of poking with a multimeter and I believe the pinout there is flipped in relation to mine.

The 20879-040E-01 (board mounted connector) datasheet does not specify which pin is 1, but the drawing for the mating COTS cable sold by Digikey (PN 81466-100B-02-D) clearly shows a pin 1 location:

I followed the convention from the 81466-100B-02-D drawing and it seems the Framework mainboard is reversed. Can someone on the Framework team confirm this?

I don't love the idea of spending money on another expensive board spin to remedy this. Can someone recommend a vendor that would be willing to do a custom Cabline-UM harness to flip the pinout?

Thanks!

I'm developing breakouts for the input connector, and I realized I have no idea whether there's any current limiting on these pins. Are there any resistors (or other current limiting mechanisms) on the mainboard before any of these signals reach the input connector?

Board designers get quite a bit of freedom when it comes to wiring up M.2 slots - as subsets of designed-in functionality can be omitted, or pinouts can be changed, in some cases (i.e. CNVI taking up SDIO pins, as can be seen in Lenovo S340 schematics). I have questions about the wiring of the E-key (commonly used for WiFi card) slot, which parts of the E-key socket specification it implements, and any extras it might have.

How many PCIe links does the E-key slot have - one or two? As in, one x1 link or two x1 links? Does it have I2C? What kind of control signals does it have? Does it have SDIO or CNVI wired up? Would appreciate any extra details. Ideally, there'd be a full pinout available in Pinouts.md.

The cut cover section R and I prevent the ethernet card from seating properly by about 2mm

I was looking at the schematic, and it worries me that the symbol for the input connector uses odd-even numbering (like dual-row pin headers), instead of counterclockwise numbering we expect for such connectors. What kind of numbering does the actual footprint on the motherboard use? Does it match the Amphenol datasheet footprint numbering, as shown below?

Can you post the FAN CAD models. We have the heatpipes with the MainBoard CAD but not the actual FAN assembly. Thanks!

I'm starting on the enclosure/base design for my Framework display external monitor project, and while the Display and Hinge CAD models are already quite helpful, it would be really nice to also have access to models for the bezel (most notably for the extruded notch at the bottom), and the actual Top cover everything screws into. I'm working with an original one, but I'm sure people would be interested in the new CNC version too.

Hi, please release the cad model of the motherboard with the overall dimensions and fixing points. Ty

Hello,

I was happy to find your .stl / .stp files for the printable case, but I was wondering if you would agree to publish a less opinionated type of documentation (I mean file format wise), so that people would be in a position to build that case through other means than via home 3D printers?

Just plain blue prints with exact dimensions would be great. I may also be able to hire a local shop to make it for me if I could get .dsf / mazatrol files as well, which could be super nice (although I'm sure it's a much more niche thing for me to be asking)

Thanks in advance,
Dorian

General notes states that parts should "confirm", whereas the proper verbiage is "conform".

In attempting to get the clear keyboard etched I've discovered a lack of information regarding the keyboard.

It would be highly useful to myself, and the rest of the maker/DIY community to have the font, and exact variation used (Medium 500?), any other legends for non-text keys, the exact dimensions for the keyboard keys, and space between keys etc. Bonus points for 3D models of each different size of key. Please and thank you!

Do you plan on releasing design files for the mainboard & going for https://www.oshwa.org/definition/

Or will it remain open(ish) with the schematic?

Perhaps you could release older versions as truly open hardware when a new revision is released?

I see there's a bottom cover version r and version l, does that mean you can't fit both the audio board and wifi?

Is it SWITCH or FPR_CTRL?

Hello,
I would like to make a custom case for my new laptop. For my old macbook, I modeled the gross shape of the macbook and the interior of a pelican case. Then I booleaned cut one from the other to get a great shape for a foam insert that would fill the negative space.
I'd like to do this with my 13" framework, but was hoping for a rough model of the overall case so I can work with it. I don't need production ready mold files, just a 1 or 2 shell file that describes the outer shape of the laptop.
Thanks.

Designing a PCB mating with the input board connector, I've noticed that motherboard pictures showing the input connector don't match the Pinouts.md-stated 10156000 connector pictures on Mouser and Amphenol website. For instance, there's large pads to the sides of the connector, which are not present on the Amphenol 10156000 connector (and not just pictures - they aren't shown in the connector drawings and recommended footprint, either).

Insights?

Commit added for touchpad pinout is just a copy of the pinouts of keyboard and fingerprint reader.
Am I missing something?

I suppose this is a feature request of sorts, but I work in solidworks and would love to use these solid models natively. Do you have SLDPRT files available? Do you recommend an STL editor? Thanks for your work so far.

Pins 30 and 32 are both KBL_P, looks like a copy-paste error, one of them ought to be KBL_N

To whom it concerns,

In the following STLs, the peg hole depth is to shallow to receive the pegs.

• top_cover_r_cut.stl
• top_cover_r_full.stl

For those that don't have a suitable CAD application to do the adjustment themselves, a re-export would be appreciated.

Love the case, and much love to the Framework Team.
