you are right there about the Z but the limits help in two ways.
First you can have your machine home to the upper switch which just means that at least it knows where it is at the start of a run (that is what got me).
But my thinking is I now use a thick tool plate or my rotary table and I set the lower limit so that the longer tools still can't cut down past the plate.
Currently the longer tools will cut into the plate but not all the way through unless I run something really long. Obviously it is not a fool proof system and my playing the fool will probably still manage to mess up again but I think it 'safer' than before. Ultimately I want to use some sort of tooling setup that better controls the tool length. |
