Thanks for your feedback.
I think, it should be Flatness, the total length slot is 250, so each every "Square Block" is 25x25 and with Flatness of 0.03?
Parallelism or Flatness + Square
How does it works here?
Does it means each "Square" block needs to control at 25.4? Or every "Square" block is 25.4 and need controlled at 0.03 Parallelism/Flatness?
Thanks.
