Cutting PE foam

Hi folks.
I am cutting PE foam with my 80W laser. The foam is 30mm thick. It works well, but I am struggling with the start of the cut. As you can see from the picture, it creates a wider mark at the start… I need this to be smooth… Any suggestions on how I can solve that…?

You’d want to do a lead-in cut so that the start of the cut is away from the finished part. I don’t know how to do this in LB but if it is possible I’m sure someone will share their technique.

Yeah, this is exactly it. I guess I should start by adjusting the vector path in Illustrator, creating a lead-in. Never had the need for something like this before.
Would be an excellent feature for Lightburn to implement in future updates.

A lead-in might be as simple as adding a short straight line segment at a tangent to the curve and then specifying the line segment as the start point for the object.
