      I would like to point out that many of the OpenBuilds parts I am using could be 3D printed if all you want to do is use it as a 3D printer and have no plans to add a spindle to it at a future date, as the 3D printed parts would flex too much for routing or milling., But for a 3D printer they are more than adequate and would save a large amount of money. So the choice is yours.

      As well, I am open to providing the acrylic laser cut parts for a small fee for anyone who wants to use them, but do not have access to a laser cutter. 3D printed parts could be made available as well, PM me if you are interested.

      I finally started construction of this printer after months of various design iterations on paper (and in my mind) I tend to design on the fly after I have settled on a concept, and this project is no different. During the initial mock up today, I changed a few of my design choices to eliminate as many 3D printed parts as possible, and to utilize as many OpenBuilds standard parts as possible, to allow others to build it without access to any specialized equipment such as laser cutters or 3D printers. As it sits now, there are some laser cut plates, however you can substitute the original OpenBuilds plates in their place, I just like to prototype using acrylic as I can make changes very easily. And the current design uses 3 3D printed parts, but I have an alternate way of doing these using Openbuilds plates.

      Project is on hold until I receive my order of Tee nuts, as I have run out of the ones I had. Should have them by the end of April. Until then I will work on getting the laser cut and 3D printer files uploaded, as well as updating the BOM.

      April 24, 2018

      Finally received my Tee nuts and can continue the build process. Will be working on the Y axis today, as well as figuring out how I want to deal with cable management, I really like using slot covers to hide wires, but cable chains will be inevitable given the fact there are moving parts on this printer.

      Redesigned the X axis back plate that was 3D printed to be a laser cut acrylic plate. Will post a picture of the redesigned plate when I can find my camera again (lol) Will be posting files tomorrow for all the plates.

      One of today's adventures has been creating the Y axis carrier plate for the heated bed. Since it is very large (360mm X 360mm X 6mmm) I decided on a 6 wheel design, the usual 4 wheels in the 4 corners, but added 2 wheels in the center to help support it and keep it from bowing (Picture to follow soon).

      April 27. 2018

      I had to modify the base of the printer to allow the Y axis carriage wheels to pass over the cross bars, I placed the 3 20X40 extrusions vertically instead of laying flat. I need to make 2 new holes for the Y carriage center wheels because of this change (They were spaced for the 40 mm width, and now it is 20mm) This is an easy change, will just use my drill press to make the change to the Y carrier plate.

      Just finished up the design of the Y axis motor mount and idler plates. Not sure if I am satisfied with them, so I will think about the design some more. Started mounting motors today, still playing with cable management ideas, I want as many of the cables as possible to be hidden from view, I like a clean look in my designs. Mounted the heated bed to the carrier plate then remembered I needed to add the 2 center wheels so off it cam. Will put it back on tomorrow.

      Decided on a Cohesion 3D remix board as the controller. Designing a case for it today.
      1. Special Notes

        BOM is incomplete at the moment, will be updating it as I progress on the build. Files will also be uploaded as soon as I finalize the design.

    Reason for this Build

    I have always wanted a large format 3D printer, and figured that using OpenBuilds parts would allow me to build an accurate, strong machine using an easy to prototype system.
