I think all of you have put your finger on the button. Can I use other variables to include the lines:
if (incomingByte == 'X') {
Xstepper.enableOutputs();
Ystepper.disableOutputs();
Xstepper.move(n);
Xstepper.runToPosition();
within the scope of variable n?
is the idea of storing the variable using SRAM ridiculous?
