The kit will come with a laser that you can change the focus of by hand ( rotate the laser)
The plan is to be able to tell blender what the Dot size/ focus of your laser is at the top and bottom of your print ( it wont change much over the course of most prints)
This will help blender move the laser at a speed that cures the resin correctly.

In the pro we aim to change the focus dynamically during the print using an arduino!
