    I love the general design, but wouldn't that make the x-carriage much heavier?

    Please elaborate on why you think it would be heavier.. do you mean versus using a Cbeam Gantry?

    those two versions shown have two Z motors.
    but otherwise yes Cbeam will be a heavier build.

    I have a Wilson TS that is using "substandard" motors (12V, 0.4A, ~30 oz-in), and I was noticing the frame was a little bit wobbly. This looks like something that is a little better direction.

    Like it
    Would suggest rearranging the stationary extrusion to allow for less exact cut lengths

    I recently made a voxel ox similarly to this, and it's a great machine however I have some criticisms which you may be interested in.

    Firstly, the build area is fairly small compared to the actual size of the printer, this is partly to do with using large openbuild plates for the X gantry, as well as having the idlers and motor mounts within the frame. There is not much that can be done about this unfortunately due to the design, but it is quite a shame to give up 200mm or so of space (100mm each side). Could possibly use the belt and pinion style and have the motor directly attached to the x gantry?

    Secondly, Marshall Peck designed a nice y-idler for the Voxel Ox that allows you to tension the belts, but there is nothing to tension the x-axis belt. These really need to be piano string tight to get good results. I designed one that places two idlers on the inside which allows one to be used as a tensioner by pulling the belt down.

    Thirdly, the prusa style moving bed limits your max speed as you really don't want to be flinging around a heavy piece of aluminium. Bed adhesion becomes even more important.

    Fourthly, motors on the top. This is a minor complaint, and using C-beam and only 1 motor will certainly help. Basicly, it makes sense to not have weight on the top of the frame as it makes the machine less stable.

    My main point is, what are you using this machine for? Is it just 3d printing? If so, the c-beam is overkill and you'll get just as good results using 20x80 v slot with the corner brackets. Saying that though, I have been tempted to upgrade to C-beam just for the neatness it adds to the design. Despite these though, its still a great machine and Its produced some great looking prints

    Is it just me, or does it appear that the new TEVO Black Widow printer is a direct implementation of this design?

    I liked what I saw of that printer, but once I saw that it was c-beams and v-slot extrusions, wanted to buy parts directly from openbuilds. I found this project while looking to see if anyone had any dimensions for the TEVO printer.

    All that said, apparently they really liked your design idea, even if their way of showing it leaves something to be desired.
