No. Unfortunately a HAL component like Carousel can only access the rest of the system via HAL pins. No direct g-code access and no file access.
Are you absolutely dead-set against adding one more sensor for home pocket? It would make things a lot more reliable and fault-tolerant.
(consider what happens if the PC crashes before it has the chance to save the pocket to file)
You could add an extra input pin to the component, then pass the actual position to that pin from the G-code persistent parameter.
Code:
pin in signed init-position;
...
case 0: // waiting at start
if (init_position >0 && homed == 0){
current_position = init_position;
homed = true;
}
if (jog_fwd || (jog_rev && inst_dir == 2)) {
if ((inst_code == 'I' || inst_code == 'E') && ! homed){
state = 10;
break;
}
