One more axis.
I left my 2D plotter away for some time. Back with the 2nd axis: Y
For this Y-axis, I use 2 stepper motors, hence 2 servos, one for Y and the other one for A, configured to duplicate Y. I added two jumpers as shown here:
Initially, both stepper motors were turning in the same direction, which considering their position on the board is wrong. I needed one of the to turn in the opposite direction: easy, it's just a matter of inverting its connection on the CNC shield. Note the wires: black, green, red, blue on the left-inside (A) and opposite on the right in-side (Y).
I also created a wood box to hold electronic parts together.
Closed, the PC sits on the top and I have an emergency stop on the left in-side that works !
And now the result in motion:
Note just for the record: few useful G-code commands

- ? = Current Position/Status
- $$ = Current Settings
