Re: the spindle, your VFD may not be configured for software control. There's a whole configuration to making that work and then some additional wiring may be necessary as well. Also, depending on what electronics are used in the control box you may need a PWM to 0-10V converter to control the speed. I just got a new 6040Z myself a couple of months ago and have been spending a good bit of time going through it making these type of changes. My unit is the "black box" controller.
In addition to the Spindle control modifications, I've added wiring from the E-Stop switch to the breakout board and I'm still deciding if I want to remove the input power to the 24V DC power supply from the E-Stop switch. In the original configuration, the E-Stop simply cut off that power and it took a good second or so before the power would actually drain off. Additionally, Mach3 had no idea that the E-Stop had been engaged so just kept merrily plugging away at whatever it was doing so all synchronization was lost. Adding in the E-Stop signal wiring to the breakout board solved that, but I'm stil leaning toward removing the E-Stop button from the power circuit so that Mach3 has a definite chance of sensing the E-Stop condition.
There is a good video showing how to configure the VFD and wire it up for software control of the spindle. Just google "NowForever VFD". I'm not sure if that's the VFD you have (mine is) but it will give you some good ideas of what to check for in any case.
Hope this helps,
