Hello dear reader, in this article I want to share my experience building a milling portal machine with numerical program control.
 
 
 
 
There are a lot of similar stories in the network, and I probably will not surprise anyone, but maybe this article will be useful to someone. This story began at the end of 201? when I was accumulating a certain amount of money with my friend, a partner in the development and production of test equipment. In order not to just skip the money (it's something young), they decided to invest it, after which the idea of ​​manufacturing a CNC machine came to mind. I already ...

At the work the transmission used for transfer of energy from the engine to wheels, strongly enough rustles. The first reason for this undesirable effect is that the transverse and axial forces resulting from the transfer of energy from one shaft to the other by means of a pinion have an undesirable mechanical effect on the bearings and the housing. The second reason is the flexibility of the various components of the gearbox, including bearings and housing, which can also lead to vibration. The variable stiffness of the gear clutch in the gearbox causes a constant vibration transmitted to the ...

Recently, under Linux, a new CAD product from Bricsis came quietly and almost imperceptibly, so Linux was supplemented with yet another must-have tool for virtual prototyping . The company Bricsis positions its product as absolutely free, a quote from the official website "BricsCAD Shape is free for all users and does not have any restrictions for commercial use."

Auto-Deck made the walls different, but the designers came and drew the walls at an angle of ??? and ??? degrees. Therefore, do not put the dimensions between the walls. This went on for a long time, but now the Great Macro Equalizer has appeared, it will return the walls to ??? and ??? degrees.
 
The macro corrects the walls, which are drawn with an error of up to 1.2 degrees relative to the parallel or perpendicular to the chosen wall pattern.
 
The algorithm is as follows: the user starts a macro, selects uneven walls by one piece or frame, then selects the wall of the sample, relative to which ...

 
 
The nanoCAD menu files have the extension .cfg and a structure that differs from the menu structure ( * .mnu , * .cui , * .cuix ) of other CAD systems. In version 8.? there is support for macros that can contain several commands and parameters, as well as LISP expressions.

Support for LISP in nanoCAD appeared a long time ago and was associated first of all with a special LSP command that opens a LISP-console intended for input of expressions and analysis of variables:

Release 8.5 took the next important step forward, now the input of LISP expressions became possible on the command line, in addition, the support for the PAUSE symbol appeared. The changes described in the article are included in release 8.? starting with the number ???.262? build 4133.
