10W cuts through and then it doesn't cut through

Has anyone had the problem of the CR Laser Falcon Pro 10W cutting through so it falls out, and then not cutting through? Same 1/4 “wood each time. I have had this before, and they sent me a new 10W laser and nothing has changed. I have it on the Engraving/Cutting level at 100/100/4. Just did 5 passes with just the circle to cut out, and it worked, but why did it work perfectly before engraving with 4 passes, making 6 of the coasters with the engraving? I am wondering if I should go to the 2nd level of focus and try to engrave and cut.
