Unscathed,
Firs things, you need to do the CAD and CAM side before the machine,
Hang around someone who had been there done this.
43k and then what ????
Have the program, fixtures and materials ready and set-up for when the machine is production accepted,

I have made chips and money before the machine service mans car leaves.
