Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

G'Day Guy's,
           Well with the GUI Controls now available on HDMI with my recent coding for the Surface Grinder Project when I started thinking about this new project the fact we have 4 axis to play with I do have a few spare 3 jaw chucks so a new A axis project is going to happen and just ordered a stepper motor and DM556 micro stepper for the project.

Now on my Surface Grinder Project Lyle suggested a 1K/22k with a BC337 translator to the DIR/STEP outputs so does this give full isolation to the pico pins ?

With the new board to be made for the breakout board to my CNC I will have a go at doing a schematic first so it can go past the brains trust before committing to design the board.

Regards Bryan
