Robotics 3d printer

Motivation

I’m interested in robotics and smart homes. With this I also fall in love of the idea 3D printing for prototypes. Anet A8 was my choose of 3D printer because he comes with the do-it-yourself idea. Getting some expiriences in how 3 axise and alot of components work together, is not bad before starting creating own robots.

Low cost and a large community for getting updates and help was the finale selling point.

RepRap is humanity’s first general-purpose self-replicating manufacturing machine https://reprap.org/wiki/RepRap.

Improvements With 3D Printer Printed

Anti Wobbling

Wobbling is currently not an issue anymore.

The most effective update was the E3D V6 extruder. To be exact, moving the wight of the stepper motor from the axis to the frame did the trick.


X Axis

Have to print a new version before it is too late.


E3D V6 extruder

One update
did it all

E3D V6 extruder — Worth it!



This update improved the print quality, increased the printing tempo, fixed wobbling issues and reduced the noises. E3D V6 from ebay
