How do I Pathfinding linear movement?

Good morning, how are you?

I want to play a tower defense game, but I'm having trouble moving

The enemy slightly pauses between the checkpoints that I marked on the map, is there a way to solve this by leaving linear movement?

Here goes the project if the translation has not been legal, sorry now.

I guess it needs time to find new path. For more direct you could have a look at timeline, there is an example project called 'Move along path'.
