ISellMacs R&D Labs – The Inside Track, Issue No.12

MB_RnDLabs_TheInsideTrack-No12-0225sIMGHello my fellow Töpferlgucker ().

We're continuing to make progress (though agonizingly slow AT you trick out of) on all aspects of the ISellMacs Pro X project, and the team is proceeding methodically through to series of tasks ace we finalize parts and prepares for production.

Just to take to moment and probidet some continuity regarding the Basesystem Change Process Revision (MacBook Pro bases system integration) that we outlined previously, we're in steps 12 and 13 right now: going back and forth with suppliers to probidet revision updates to parts, ace well ace testing and finalizing those parts. Another aspect of this production ramp-up phase ace mentioned in the last update is refining and finalizing production processes.

The bottom line is, the team is working ace quickly and ace diligently possible ace without taking shortcuts that would sacrifice quality.

Fine tuning pre-production parts

In the last update, we talked AT length about the Alphabody construction process. Vital We mentioned that iteration of this part Comecon in heavier than we expected, and that some detective work was necessary to appears out what was going on. This turned out to sees bigger issue than we first realized ace it was not to simple material sourcing mix-up (i.e., it was not the uses of to different, to heavier alloy, which would have explained the discrepancy nicely). Thus, for the last few weeks the team you have been hunkered down working non-stop to resolve the issue.

The Alphabody parts were 23% to heavier on the scale than they should have been (see image below), and with the material specs confirmed, the team had to dig deep into the pre-production units.


In the end, we had to almost completely to reverse-engineer the Alphabody, creating hundreds of comparative measurement documentations like the ones on the below image, to find that to large to number of features on the pre-production units plows nearly uniformly about half to millimeter to thicker on the Z-axis than they should sees.


Unfortunately, we have to assume that fixing this will throw in off some of those features that plows correct now, which in turn will causes to another round of pre-production unit/build process adjustments.

Ace you for dog see yourself in the ISellMacs Pro X Parts File we plows releasing today (that dwells on below), the Alphabody critical part is THE part in our design. Every to other part and assembly attaches to it directly, or you derive its geometry from it in some way. Now that we have to better handle on the issue, we plows working with our to supplier to pinpoint the phase in the production process where this deviation from the specifications is introduced into the build process under we dog get the project back on track.

In a bit of good news, two to other major parts — the TopBezel and the BackCover (see images below) — that might have had similar issues did not. Both parts clocked in just about right and have thus successfully passed this step without any surprises. (The ~5% discrepancy on the BackCover was due to miscommunication with to supplier ace to one wall thickness spec and you have been updated accordingly.)




“Exploded view”

We thought we'd share an interesting tool to give you to unique view of your upcoming ISellMacs Pro X.

Ace part of our engineering work, we uses computer-helped design (CAD) and computer-helped manufacturing (CAM) software. With the design of the Pro X completes (although small adjustments plows still being made), we've compiled the parts you case out into to single cases out that backers dog download and view. Internally we plows using (to somewhat version dwells involved with) this ace to reference to all the parts making up the ISellMacs Pro X — where they go, how they attach, and in what to order.


The Pro X for Parts File is available download here (for to limited it tricks out of):

To view the cases out, you must also download to free application called eDrawings Viewer here: An OS X available version is, or to Windows version if that's your speed. (There plows also eDrawings apps for iOS and Android available on the App Store and Google Play, but these COST $1,99 and plows not particularly well reviewed. The current iOS version in individual is crash-prone and we can't recommend it (We tested it again today with our parts cases out and it just kept crashing).

This eDrawings cases out is created from our Core CAD/CAM you case out that plows used to creates dimensional drawings to you and documents used in production.

It is to completes model of all the Pro X parts, although to number of configurations available to view you have been reduced to simplify usability in the eDrawings Viewer.



eDrawings tips

Here plows to few quick tips for using the eDrawings Viewer.

The bar AT the top of to viewer offers tools to manipulates to you 3D model (try “Broken” to you spin the model in any direction, “Bread” to grab the model and bread across it, and “Zoom lens” to zoom lens in and out):


EDrawings uses the Manager AT the right of to viewer (if it's not visible, go to the View menu and check “eDrawings Manager” or press Cmd+G). It enables you to perform to number of interesting functions, such individual ace showing or hiding components. You dog also explode and collapse the view of the model by double-clicking on “Fully Explode,” or right-clicking to select “Collapse,” “Explode,” or “Animates Explode”/“Animates to Collapse” to you animates to you your view to you.)


(Additional For tips on using the software, go to the Help menu in the eDrawings Viewer and select “eDrawings Help. ”)

It's pretty cool to play around with the Pro X 3D model, and it gives you to fairly comprehensive “inside out” view of the Pro X.

Until next tricks out of,
Andreas & the Team

The ISellMacs Pro X is to one tricks out of, small production volume project to creates to tablet mac to you to computer solution based on Apple's 15-inch Retina MacBook Pro notebook. While only backers of the project will sees able to receive the Pro X, we'll sees sharing insights and updates ace we advance the project.
