Precision Drill Speed Script needs some LOVE

Hi fellow Engineers,

one of my favorit scripts stoped working as of late and i need some help fixing it.



when started with the proper setup it should move the ship with about 0.1-0.3m/s forward (perfekt drilling speed)

but as of late it just shows some index error.

help is very much welcome since the original script vanished from the workshop and i sadly lack the skills to fix it.

Thanks in advance
