How can I send very long scripts for 3dprint? with more than 2000 points

Something that can be done could look like this:

you create a loop which run until you receive an end signal
  if the end signal is false
    first you wait that the position you receive is different from 0 and different from the previous
    reset a signal that say the trajectory is done
    you memorize this new point in a variable
    you do a move trajectory to this new point
    you send a signal that the trajectory is done

You could use others variables to decide which kind of move you want to do and for example get different speed.
This would give you a short program with everything done from the Ethernet. But it’s just an idea, I’ve never tested it.
