Gsender z height adjustment causing concerns

Okā€¦ I need some help please.
This was not doing this on the previous version of gsenderā€¦ so I need report an issue.
When attempting to engrave or cut with the laser mounted in front of the router, after setting ZERO for x y z, once I hit the start button it takes the laser all the way to the top of the z rails. Because it is hitting the top, it stops, makes that loud noise that tells you ā€œi canā€™t go any further.ā€ Drops back down and starts the cut.
However, it is dropping so low passed the actual z zero point. Therefore the laser is approximately 1 in lower than where it should be.
In gsender the only z movement I have is 0.25". I do not see any other options to change.
I attempted to take the laser all the way touching the board before hitting start, but it does the same thing.

Responsesā€¦??? lol
