Clones not cloning fast enough

I'm making a drawing project, that uses clones in stead of pen: clones appear at your cursor when you hold down L-click. Sadly, the clones won't appear fast enough, so if you move the cursor too fast, it makes huge gaps in the lines, and I can't figure out a solution.

Edit: I need to be able to save the coordinates of the different points, make lines, and erase dots, for a project.
