5, you can use SSH, RCP and other means to transfer files, of course, can also be directly connected through the socket. ...
Added to the module and split the file after the design is very convenient, just like building blocks, one by one to join together, will be more than one part of the assembly.
Code is very convenient to write. Are very simple commands to combine.
Very suitable for developers to use, the design of a simple model is very convenient. ...
1, the design of the arm first version of the robot arm: arm_base arm base
Arm_1 joint 1
Hand manipulator to achieve one of the most simple, mechanical arm, the need for 4 steering gear, in order to facilitate my purchase of the steering gear is the same as the MG955. 2, the joint design is very easy to find a mg955 steering gear from the Internet engineering. Know the details of the parameters.
Add a hole in the flange plate on the steering gear support and put in the disc.
On the other end and the steering gear above the metal copper teeth fixed.
A screw hole is provided in the middle of the metal copper tooth...
It is very convenient to use openscad to design.
Can make a steering gear support, screw holes, position, can design their own.
It only takes 20 minutes to print such a small part, and the parts are very strong.
The efficiency is very high, can be very good use of the advantages of 3D printing, but because of their assembled printer error, so it needs to be adjusted to make the appropriate parts.
Openscad is very suitable for programmers to program, as the code to design 3D parts. ...
Domestic, foreign robot exhibition. China has a lot of enterprises is also very good.
Now China wants to develop the robot. By the Chinese people's wisdom and diligence into the world's advanced level must be no problem.
China dream come on. ...
Security Spring, formerly known as Security Spring, is a framework for providing secure authentication services in the Acegi project group.
The most used in the security framework is security spring.

OpenSCAD is a very good CAD software, in accordance with the developer to use.
There is a command line, very simple, you can write programs like drawing 3D image.
Compared to AutoCAD to be more simple, it is very convenient to do some small parts.
Just like with the python program development, but this is the output of the 3D image. ...
Although the printed parts and steering gear did not match.
But a little bit further forward. Continue research robot. Start their own design parts.
The biggest advantage is that it can be adjusted, can be customized, you can do according to their own imagination. About precision is a little bit worse.
How much is how much can not be a little bit worse. First bought a steering gear. The parameters above are: 40.7*19.7*42.9 then find a model of the machine, print the next. ...
1, needs to develop a desktop client program for running shoes.
Do not want to use the java development, start slow, the client program. Development is difficult, the people will be less SWING.

1, the problems encountered
My wind turbine outlet is broken, the buyer wants a model file to start printing.
It's because this part is too close to the spray head.
But also printed on the side of the two are good, while dislocation, began to think that the X axis, the side of the tight side of the. But shut down the move, found no problem. 2, to solve the problem for a long time to understand that the original is caused by uneven platform.
It will be much easier to solve. First boot set home auto, and then shut down.
Because this time stepping motor in order to maintain stability will lock, do not move at this time...

###1, about 3D printer
At home and abroad are very popular at home and abroad. Direct drop 3D design print into model.
A guest weapon. As an engineer must have a research.
Direct online shopping materials, began to assemble.
Work during the day and study with colleagues at night. Spent 2 nights at last.
###2, the process is very hard
The first assembly of such a complex printer.
Experience is not rich. Basically a part to be installed more than two times.
As a whole does not understand, often affect the line, or the installation of anti. There is only one correct way to install, so you must remove it, and then install it again. Take a lot of detours.
It's all right...
