    Hey guys just a heads up. We updated the build with an easier to understand xPRO controller diagram in tha main build page that should help to see how to easily wire up the machine to the xPRO controllers.
    Hope this helps.

    My bundle seems to have only sixteen (16) of the 25mm screws (see attached bundle list photo), but the video build instructions call for at least 20 of them. (Eight in Step 14 @ 45:33, eight in Step 15 @ 49:05, and four in Step 16 @ 53:58.)

    Any suggestions? I'm guessing I can use some of the extra 27mm screws (mailed separately) to mount the NEMA 23 motor in step 16, but I did want to check on the discrepancy between the video and what was shipped.

    Thanks!

    Actually, at 54:36 the voiceover clearly says "20mm screws" (and the video shows 20mm screws), so I suspect it's just the title slide at 53:58 that incorrectly says "25mm M5 screws". The longer 27mm screws I tried are a bit painful to install, since the spanner wrench can't easily grab the nut from the end as shown in the video.

    Hello Pm. It is my understanding that a second package was shipped to you. The Part Store will be reaching out to you with further details.

    I was comparing this Sphinx 1050 with the smaller Sphinx 55 to see which parts were different & noticed the sketchup file for these 2 sphinx machines both have 2060 extrusions along the Y-axis base, but the parts list & video build show 2080's for this larger Sphinx. Also I notice that drop in tnuts are used instead of regular tnuts in some places. Could I just use the regular tnuts instead if I load them in the channel ahead of time? In a folgertech delta 3d printer build where they used the drop in tnuts they were problematic for me.

    Hello David. We need to update the model to 20x80 that we ended up deciding to incorporate. As for replacing the Drop In Tee Nuts with regular Tee Nuts - this shouldn't be a problem.

    Thanks for the info. I will order some extra regular tee nuts when I decide to buy this. I watched the build video for this & wiring build also. I like that open electronics case, but I thought the top should be covered for possible aluminum chips flying in. I decided to design a cover for this before purchasing to see how it looked. Here is what I came up with so far. I made a 1mm thin plate for the front to cover all the exposed holes & an angled top plate with a slot in the back. Seems like this should keep the debris away from the electronics & still allow good air flow. Does this look like a good idea? I will wait until I order this kit before test printing. The last screen shot shows the print orientation of the top cover.
