A working ATC for small sized CNC machines.

Video demonstrations taken with SainSmart 3018Pro toy.
I will add more videos to this thread,...

Pfffttttt....

I took mega 2560 board for lathe, since I need extra timer for chuck rotating, when turning basic shapes...
So, now with potentiometer & switch & adc input + timer5 I can rotate...

And reason for these:

1) Still missing chuck rotation while chamfer turning !!!!!!!! MANDATORY !!!!!!

Now I had to expand grbl code for Mega2560. I took timer 5 in use and an one analog pin for...

I got that already, but!

Somehow, I don't get threading work for inner threads. It always start bottom of thread.
Not step by step from inner surface to bottom thread, outer surface. (Always same direction, when normally...

3D printed prototype worked as planned (of course couldn't use for routing, but to check, that get tool / leave tool mechanism works).

Now I'm working with steel & aluminium real version of it....

(I'm rebuilding my lathe to CNC version).

I'm going to make threads (My lathe)...
