I have a couple of questions. The first one is about the plate marker attachment. What is the procedure to adjust the height of it? The water table assembly book just shows a picture of the plate marker nd where to mount it along with a picture that shows what bolts need to be use to adjust the height. It just doesn't have any instructions on how to set the heieght.I went to use it with the a program I created to work with it and all it did was just run in the air. It didn't get down to the material. The second question is about timing. It seems when we are starting our cut it pierces and then it sits there for a few moments before starting to cut. This happens intermittently. Sometimes it does the waiting game and other times it goes right away. What is going on or what can I do to adjust this to work the same all the time.
