View ArticleIs there a method to use regular 1" square aluminium extrusions?
I happen to have three lengths of 1" square aluminium extrusion. I realize openbeam, t-slot, v-groove etc is better, but I have here and it is free. I'm thinking of a Cerberus Pup/Kossel Mini printer....

Just curious, That colored I'm guessing Polycarbonate bed. Is that for show or buildable? How well will that standup? Looks cool.

I thought I doodled the inverse kinematics up at the start of this thread. [forums.reprap.org] They need a little updating for the new design. Nicholas.Seward used essentially the same math, but with...

A few notes: I like simplicity so I have done a few things in my design to simplify the math. What Annirak has written above will cover any generic Simpson with a concentric extruder. (Off axis...

Imagine a square sleeve. Split it diagonally. Incorporate 608 bearing mount points so you can have bearings riding on all four sides. I would do a 2-1-2-1 pattern for the bearings. You can zip tie the...

If you want to make a precise machine that doesn't need a lot of maintenance then belts are a must. In my book, there are two reasons to use fishing line. It is cheaper. It can do routings that belts...

The bed is orange acrylic 1/4" thick. It works very well for PLA and we have done several prints on it already without any issues.

Thank you I'll have to hobble something together until I have a working printer to make proper parts

Thought I'd chime in here as although there is no reference, it seems you're referring to the Deltaprintr if I'm not mistaken :) There are a couple of reasons that we decided to go with strings. 1....

Here is a no printer version. All you need is... 2x2 lumber (1.5"x1.5") 6x 5/16"-2.25" bolts 6x 1/4" washers (You need the smaller washer to get a tight fit on the bolt.) 6x 5/16" nuts 6x 608 skate...

Storing calibration data on the host may be better for multiple toolheads anyway? i.e. offset extruders, varying nozzle sizes, a rotating toolhead?

As an (electronic) engineer I find many components of RepRap printers heavily oversized and therefore also overpriced. If you develop a product you should always use the components that serve the...

Thank you very much. That seems very doable. I will post pictures when I'm done for any future strapper.:-)

I'm being pedantic. Quotenicholas.seward The Annirak Drive or the Proportional Gear Joint Drive both make the relative rotation of one of the steppers proportional to la, lb, or lc. Not quite. I mean,...

I love this printed gear bearing. Maybe not entirely helpful in this case, but still inspirational. [youtu.be] You could print a circular inner bearing gear path and custom outer cam profile?
