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.
