    Starting this thread to allow us all to have a single place to track our builds for the D-Bot :)

    I am still in the process of trying to find somewhere here that will supply the v-slot rails cut to size, think I do have that sorted now.

    Got approval from SWMBO to buy all the bits though!

    Once my latest orders arrive from Aliexpress I will be upgrading my Tevo and then printing out all the parts for the D-Bot, but where I can buy metal parts in place of the printed ones I will be.

    Any chance of you guys posting link to the parts you bought please?

    I've got a idea. How about we each make a post here and up date that post only with the parts we buy and where from
    and any problem we've solved.

    Gonna try printing a part at the weekend and I'll let you no the outcome.

    Glad to see so much interested in 3D printing in the forum.

    Fwiw, here's my shopping list so far.
    I'll update with stuff like required numbers of certain bits pertaining to my particular build.

    Original D-Bot Bill Of Materials HERE
    Original D-Bot Build Guide HERE

    Note: I'm using the alternate frame lengths for a 300x300 version found in the appendix of the build guide, adding a front Z carriage mount (like this) and replacing the original bowden extruder/X-carriage design in order to go with a direct drive system using an E3D Titan extruder.
    Here is a link to the redesigned carriage. Check the 'made' tab for better pics.

    This will also be a 32bit, full 24v system, so obviously choose 12v alternatives to applicable parts if that's what you're going with.
    Or you can bugger about with relays.

    Certain printed parts are being replaced by off the shelf components, simply to save time and effort for the person that will hopefully be printing this for me. The aluminium corner brackets should also make for a stiffer frame.
    These parts are listed in orange text.

    Frame Materials
    V-Slot supplied and cut from http://ooznest.co.uk/V-Slot/Linear-Rails

    Mechanical

    Mini V Wheels http://ooznest.co.uk/Mini-V-Wheel
    Mini V Precision Shims http://ooznest.co.uk/Mini-V-Precision-Shim
    Nylon Spacers (1/4" length) http://ooznest.co.uk/Nylon-Spacers (may possibly have questionable tolerances, so might be better to print the wheel spacers instead)
    Lead Screws http://eu.banggood.com/Wholesale-Wa...opper-Nut-3D-Printer-Z-Axis-wp-Eu-979643.html
    Flex Coupling http://www.banggood.com/5mm-x-8mm-A...Stepper-Motor-Coupler-Connector-p-994359.html OR http://e3d-online.com/Flexible-motor-coupling-5mm-to-8mm
    16 Tooth GT2 Belts and Pulleys http://www.ebay.co.uk/itm/252426216733?var=551279383080
    All of the bearings can be found on ebay. Just search their model# on there

    Hardware
    Corner Brackets http://www.banggood.com/10pcs-20x20...gle-Bracket-Furniture-Fittings-p-1056722.html (you'll need to use pan head screws, or use a round file to elongate the holes slightly or the socket heads will clash. It's a very quick job)
    Square nuts M5 DIN562 https://www.pts-uk.com/Products/Nuts_Square_Nuts_Metric_A2/A56205
    All other nuts, bolt, screws and washers can be easily found on ebay

    Electrical

    E3D V6 hotend http://e3d-online.com/E3D-v6/Full-Kit?product_id=380 24v version
    E3D hardened steel nozzle 0.5mm http://e3d-online.com/E3D-v6/Extra-...ned-Steel-1.75mmx0.5mm?sort=pd.name&order=ASC
    E3D Titan Extruder http://e3d-online.com/Titan-Extruder (choose bowden add-on, or print it via the Titan carriage linked earlier)
    Nema 17 Stepper Motors https://www.think3dprint3d.com/motors?product_id=122 (I've chosen these 0.9° versions, which are more suitable for 24v/32bit. Perhaps look at these if running 12v/8bit)
    'Pancake' Stepper motor (to use with the Titan extruder) http://www.ebay.co.uk/itm/121656401478
    24v/600w/25A PSU http://www.ebay.co.uk/itm/301610568178?var=600491465160 (Probably overkill here, but it's nice to have headroom. They also have 12v versions of varying wattage)
    24v/300w/12.5A/300x300mm Silicone heated bed http://ooznest.co.uk/24V-Silicone-Heated-Bed-300mm (12v and other size options also available there)
    Duet 32bit controller board https://www.think3dprint3d.com/Electronics/electronics-boards/Duet
    Hall Effect Endstops http://ooznest.co.uk/Hall-Effect-Endstop-3.3V
    IR Z-Probe http://www.escher3d.com/pages/order/products/product1.php
    PanelDue+4.3" touchscreen https://www.think3dprint3d.com/PanelDue Decided not to, as I can just use a phone/tablet/PC via the web interface. Saves ~£80!

    MISC

    Flexible conduit tubing I chose 9mm, which seems to fit fairly well in the D-Bot cable guides with zip ties
    Cork board to insulate the heatbed
    40mm 24v fan
    Springs for bed leveling
    Inlet socket Matches the original BOM item and will fit the printed enclosure. No LED though, but you can find those if you don't mind waiting longer for delivery or you're happy to buy 5

    Almost done.

    Oioi!

    Cheers for putting a thread up Al. :)

    Collected my nicely sawn extrusion from the engineers today, all ready to go. Currently churning through the parts on the printer. Think I found the dodgy STL, one of the brackets? Can't remember exactly which one but the gcode just resets the printer. :(

    Load more screws and fittings arrived today too, so I'm just waiting on the 2nd lead screw for the mechanicals then it's time to finish printing and build the frame up. Woo!

    Something tells me I'll be printing these parts off again when I've got the Bot up and running...

    Parts are turning out OK, but not stunning by any means. Also I think I'm going to reuse the extruder from the Tevo to begin with then try the D-Bot one when it's built. One less thing to knock up on the Tevo!

    Which square nuts did you get, and have you done any test fits yet Randal?

    Not yet, but I can tonight. I think I just grabbed them off of Amazon in the end

    ****.

    That's what I worried about and why I want to go with T nuts... Just not willing to pay silly money for the proper ones.

    Most of the square nuts I've seen look a bit thicker than the one he links to, and that doesn't have any real specs listed.

    I'll get the callipers out so we can see what's too big as a starter. It's bloody annoying, grr.

    Edit -
    3.8mm thick
    7.8mm wide.

    Too big, refund time...

    Can you determine which part(s) of it are causing the issue? Width, thickness or both?

    I'd say it's a bit of both tbh.
