Sketch of an idea I just had. It’s a single pillar cantilever style printer. It’s completely impractical, but fun to think about.
That’s nice design, very simple and sleek.
Its definitely possible. If I get some time I will try to get a cad design. For now I will save this image.
Thanks for sharring.
Looks very similar to my printer the eventorbot. While sleek, it suffers from lack of rigidity. The darn thing oscillates like crazy. I’m in the process of designing another printer to reuse the parts. I’m moving toward a standard box design made from aluminum extrusion. It’s possible to make the design work but you’d be limited in accelerations of the stages due to the high load concentrations inherent to cantilevered beams. I commend the creativity, but would urge against building it. Look into the forums at http://eventorbot.com
@Mohamed_Thalib_H Your welcome. Enjoy!
@Eric_Moy The main idea behind this was to use counterweights to offset the imbalances in the system, similar to a crane. In theory, it addresses the problem of oscillation by design (but I’m not an engineer, so don’t quote me on that).
The main problem I see is the power needed to move the weight of all the components.
Bukobot has a printer like this… You should check it out
The movement of both the counterweight and the stage will simply add more energy and oscillations. Clever idea though
Adding weight can be a good thing, especially to your Y stage - It can lower the natural frequency of the system, however i think you would have to not think of this in terms of vibration and oscillation - as soon as you are calculating natural frequency you are in trouble.
There are lots of CNCs built this way - but they all have a huge focus on rigidity which will be your biggest challenge, certainly can be overcome though.
