The new board for the CNC controller. The manufacturing process. Very big report :)

And so, as mentioned earlier, because of bugs found, deficiencies and changes I decided to make a new controller board. As I was producing the old PCB I already wrote. The new version, I decided to to make new PCB using different, better technology. I suggest you look at the full report.

Big report #1

Last time I worked more on the software part, but and the electronic part survived their changes. First, a big change - I decided to go directly to work with SD card and refuse permanent connection to a PC. This makes the machine completely autonomous. Also gone a huge delay between commands, and the program runs smoothly, quickly and without pause.

Already implemented:

• Switch manual control / automatic mode . Manual control means control of all axes by the joystick and two buttons. After switching to the automatic mode , the current position of the axes is considered original .
• Choosing a running program (20 different programs can be stored in the memory of the machine and executed on request )
• Correct work with curves. It was necessary to use curves programs. Now when generating program , all the curves are converted into many small straights.

First drawing + Working process video

I can happily report that the mechanical part of the actually completed! Assembled already all 3 axes. In addition of the active work on the mechanical part, very much has been done in the software part too.

Video #2!

I connect both motors to the controller board and wrote a simple program to manage them. Now the controller board rotate the motors to the coordinates, that specified in the control program. Later, the controller will take the coordinates from a connected PC.

Quick report 3

A long time I did not add the news to the blog, but during this time a lot has been done. 

I propose a quick overview of what is already done.

The controller board is fully assembled and is now being actively writing and testing the software part for controller and PC.

Printed circuit board. Part 2

And so, the PCB pattern is ready, tested and now need to move it to the board.

Need to disable all image optimization, toner saving  in a laser printer and then, print sample on an normal sheet.

Printed circuit board. Part 1

Yesterday evening drew the first version of the PCB. Maybe today I will begin to produce its. Description below.
