Fanuc 11M Questions 1st CNC Mill up and running

I got one of my vmc's running this week,my first cnc machine. The control is fanuc 11m. I spent all week in the operators manual,and parameters manual trying to get a grip on it. I set the work offset,and the tool offest. I'm just using the one tool for now while learning. I ran the first program today and the problem I had was on the safety line it called a G49 so when it cancelled the tool length offset my z went up and went on the overtravel limits.I tested it in mdi. Now I have to confess I adjusted a couple of parameters which probably caused this. Mainly I set it to start up in g43. The reason is for what ever reason in jog,handle,mode the absolute position z axis was not being driven by the work and tool offsets until you went into mdi and called the g54 and h1 for tool 1. I'm betting thats the way it's supposed to be,but I didn't like that. I want to see my z position count down to 0 as I approach the origin of G54. Hopefully you long time users of the 11m have some pointers for me. Like I said it's my first cnc,and I bought two of them so I'll be learning 11M like the back of my hand.
