    So my C2 came in today and we planned to unbox and then do some test prints before doing any real tweaking or modifications. That plan lasted only until we started using it :) it was damaged in shipping, but not badly enough to be totaled and we were able to give it some love and get it working.

    The boxes and undressing:

    20170213_164405_small.jpg

    20170213_164448_small.jpg

    TaDah! There it is in all of it's glory.

    Whew!

    Top with all of the shipping latches/locks removed:

    The latches and locks :)

    Here is is in place and ready to be hooked up:

    OK, so what now?
    Plug it in and power it up...
    20170213_170022_small.jpg

    Booted:
    20170213_170047_small.jpg

    Loading filament. I want to point out that this is a more standard, no-frill direct-drive extruder. Not a GregsWade or anything fancy,

    20170213_170140_small.jpg

    Filament and holder mounted on the back.

    20170213_170327_small.jpg

    20170213_170336_small.jpg

    Now onto the loading of the filament and leveling the bed:

    20170213_170405_small.jpg

    20170213_170631_small.jpg

    Then we launched the leveling wizard and took a left turn into the toilet...

    The extruder tried to home and couldn't... grinding, you know the noises :) So power down and abort the launch sequence...

    Took the top off (held on with one screw and some clips)

    This is what the one axis cable and rod looked like:
    20170213_173607_small.jpg
    Well that can't be good!.. That bar on the right is supposed to go out the hole it is directly next to! Bummer...
    20170213_173610_small.jpg

    No wonder there was slop in the drive cables! Here is a picture of the other side so you see what it should look like:
    20170213_173617_small.jpg

    and another of the bad one:
    20170213_173623_small.jpg

    Here it is from another angle:

    20170213_173707_small.jpg

    A little bit of head scratching and we got it back:

    20170213_173901_small.jpg


    No harm, no foul (they just wanted to make this a challenge)
    The other issue is that the other axis was not tripping the endstop either (a lovely photo of it NOT working):

    20170213_174027_small.jpg

    Here is a snap of it fixed (slide the bar over a small amount) so that the bar will trigger the endstop:

    20170213_174055_small.jpg

    20170213_174056_small.jpg

    So that sorts problem #2 :)

    A shot of the electronics under the bed just for kicks:
    20170213_174846_small.jpg

    And it is off and running printing a test model.

    I will post pictures of the test model as well.

    All-in-all an adventure in unboxing. :)

    Getting to the electronics is as simple as lifting the cover on the bottom (no juggling the printer upside down)

    This is a much more solid built printer than any of the earlier ones. It is inside an extruded aluminum case with plastic trim bits. The electronics include the (as of yet unidentified) main board and a Raspberry Pi. More to come on this as time permits. Overall this feels much more like consumer ready product than any previous ones. It still can have issues :) but at least from the unboxing, setup and run standpoint this is not anything like the previous models.

    I am also much happier with the working of this one (moving bed, fixed head -- in the Z at least) as it simplifies the mechanical parts of the printer a lot.

    The model is printing not with their small pack of filament, but rather some old (wet) cheap-as-dirt filament from WhoKnowsWhereistan.
    It is looking lovely...

    Thanks for sharing Mark. It's good to read a C2 comparison from someone who has an R1 as well. The print turned out nice.

    I have a Kickstarter R2 in the queue and I hope the QA / Shipping damage issues get clear up. When I worked for a major electronic company years ago, all prototype equipment went on a shake table at various frequencies to see what comes loose or breaks. Packaged equipment also had to survive a 3 foot drop test onto concrete to simulate UPS handlers. Manufacturers who don't do this type of testing find out the hard way.

    Keep those print photos coming!

    Assuming the R2 is an upsized version of this it will be a great printer.

    The hotend is buried in what is essentially the same as n effector on a delta printer. It is an integrated body for the hotend, fans and some other electronics. There are a lot of integrated parts which will make upgrading the hotend a challenge.

    Took a brief look at OctoPrint running on the pi after using the wizard to configure wireless (note; test print and everything was done with no computer in sight of the printer). It seems to be working correctly and I will run some prints through it tomorrow. The LCD controls on this unit are very complete. You can totally use this without a PC/Mac attached and easily...

    It is a slightly customized version of the OctoPrint software. I will also be making a backup image of the Pi SD card...

    Awesome job! Thanks Mark! Looks like a combo arduino/ramps board like my sigma uses :D, nothing fancy, just expensive. I wonder why they went that route? But explains why R1+ boards are out of stock, I'm betting they got a pallet of them bad boys lol

    Yes, it is a combo RAMPS/Mega2560 board according to the MARLIN source (that is buried in there pretty well BTW).
    Unlike the R1+, converting this back to standard boards would not be easy :)

    It also includes a filament run-out sensor. Not sure how that behaves (yet) but you can see it in the picture where I show the filament spool mounted on the back.

    I believe the filament runout is being run by the rPi, not the RAMPS. I don't recall seeing the filament sensor enabled in the older configuration.h from earlier source.

    The rPi still has a bunch of GPIO pins available to it if it only has an LCD attached, the touchscreen controller on an rPi uses SPI not GPIO.

    You can choose the power source for the mainboard here:

    The Pi has a full compliment of plugs (most are brought external):

    Not only is there room and electronics for the heated bed, there is room and electronics for the second extruder.
    I will need to figure out where the second extruder stepper mounts :)

    Sorta looks like a Melzi board
    [​IMG]
    Obviously it isn't but it kind of looks like one.

    By the way, the web page screened onto the Robo board does not exist.

    Good to see the cooling fan is more substantial than on the R1.

    From your images it looks like the rPi has 1 usb cabled to the mainboard, a second to the back of the case, the third goes where? Maybe to a WiFi dongle?
    The micro USB powers the rPi. The 100Mb Ethernet cables to the rear of the case.

    Is that about right?

    Camera port is still open, too bad rPi uses that flat cable instead of a round one terminated in edge connectors, would be easier to route. Is there a way to mount a camera like the Ultimaker 3?

    You would have to create your own mount.

    The connections are as follows:
    1-> ethernet to rear of case
    2-> USB to Control board
    3-> one open USB to rear of case and one open USB to the front of case by LCD
