The tabs are visible in easel but when the project cut it does not leave the tabs. What could that be?
Did you measure the thickness of the material with a set of calipers? The material thickness could be different from what you entered. Could be some other thing to like if you move the z axes 2 inches does it move 2 inches. Calibrating your machine is an important step. Could also be how you set the z zero on the wood. Could be the size of the taps. There is a lot to consider here.
Bit riding too deep.
- Bow in spoilboard causing uneven material height (and bottom)
- Z-zero not precise due to the above or material thickness is less than stated
- Step/mm value for Z ($102) is not fine-tuned and have a discrepancy
- Z loosing steps, causing it to ride lower and lower
