Z Axis issue 420 machine machining air

Hi guys. I am trying to make a mould. I made very simple setup at fusion 360. Only 3d adaptive but it was looking very good at simulation. I have a stepcraft 420 machine and I am using it with UCCNC software. I have been downloaded stepcraft uccnc post processor setup and added Fusion post process setting. I choose at post process window; milling, uccnc. then click save. Then load it to uccnc and it works fine with x and y axis but -6000 mm shows z axis coordinate on the sowtware and tool is turning around almost 1.5 cm upper from the material.

I found something that a forumer suggest to change scale: -1 to 1. I searched my processor and could not find that.

var gFormat = createFormat({prefix:"G", decimals:1});
var mFormat = createFormat({prefix:"M", decimals:0});
var hFormat = createFormat({prefix:"H", decimals:0});
var qFormat = createFormat({prefix:"Q", decimals:0});

var xyzFormat = createFormat({decimals:(unit == MM ? 3 : 4), forceDecimal:true, scale:1});
var abcFormat = createFormat({decimals:3, forceDecimal:true, scale:DEG});
var feedFormat = createFormat({decimals:(unit == MM ? 1 : 2)});
var toolFormat = createFormat({decimals:0});
var rpmFormat = createFormat({decimals:0});
var secFormat = createFormat({decimals:3, forceDecimal:true}); // seconds - range 0.001-1000
var milliFormat = createFormat({decimals:0}); // milliseconds - range 1-?
var taperFormat = createFormat({decimals:1, scale:DEG});
var pitchFormat = createFormat({decimals:(unit == MM ? 3 : 4), forceDecimal:true});

var xOutput = createVariable({prefix:"X"}, xyzFormat);
var yOutput = createVariable({prefix:"Y"}, xyzFormat);
var zOutput = createVariable({onchange:function () {retracted = false;}, prefix:"Z"}, xyzFormat);
var aOutput = createVariable({prefix:"A"}, abcFormat);
var bOutput = createVariable({prefix:"B"}, abcFormat);
var cOutput = createVariable({prefix:"C"}, abcFormat);
var feedOutput = createVariable({prefix:"F"}, feedFormat);
var sOutput = createVariable({prefix:"S", force:true}, rpmFormat);
var pitchOutput = createVariable({prefix:"K", force:true}, pitchFormat);
