irregular laser advancement with Engraver Master

  • hello to everything, my name is Malk and I write from Greece.
    I use your Engraver Master software, I think it's good software but I found some difficulties. let me explain better, in some curved sections the progress slows down, in this way I have features of the most burnt paper and other parts less burned.
    even if I draw a horizontal line in coreldraw, the advancement of the laser is not regular but progresses in jerks, if I draw a square the progress is very regular, I check there is a way to solve this annoying problem and thus improve this software.
    Thank you in advance
