Laser only cutting through top and bottom

I’m having a strange issue with the cut pass. The top and bottoms are cutting through fine however the sides only cut part way through. The “frame” is set to line, 6 passes 45%@700mm/sec.
Any suggestions on why this may be happening? I’m new to LB but it’s a superior product (except it doesn’t support my rotary but I digress)

      "45%@700mm/sec."
      That seems extremely aggressive for a diode laser. Perhaps it’s really 700 mm/min, which may still be too fast.
      
      "why this may be happening"
      Most diode lasers have a rectangular “spot” at the focal plane, typically wider than it is tall. If yours is like that, then:
      Lines parallel to the X axis (left-right) cut faster
      Lines parallel to the Y axis (front-back) cut slower
      The only solutions:
      More power
      Less speed
      More passes
      Each choice has its own tradeoffs that you’ll discover as you try them out.
