since we are talking pressure/angles etc, and unlikely that any of the techs mention it, while the head is in the down position, if you push/hold the STOP button and then push the flood/print button, it will actually move down into the screen and will give you a view of the depth the flood/print will push into the screen. Hopefully that makes sense. It works on older machines, but I can't verify that on newer ones as they change little things all the time. I think its a great tool to help judge the depth of the flood/print without actually having to do either
