Rotary trouble since upgrading to LightBurn from EZ-Cad2

I am having a problem with my (sic Marking) L-Box where my Rotary is turning and stopping before my laser burns, Then it is moving after the laser burns but not until after the burn is finished so I am losing part of my text out of focus. Is there a simple setting I am missing to get the rotary to move in small steps while the laser is burning. It pulsed the laser while taking small steps in ezcad2 before we changed over.
