GSK 980 MDI milling machine, I want to make my first program

I want to run my first drilling, countersinking, and threading program on my GSK 980 mdi milling machine. Upon starting it, tool 1 crashed 3 times.

The job I want to do is a steel bar measuring 1 inch wide (y-axis), 0.5 inches high (z-axis), and 90 cm long (x-axis). It has drilled holes, followed by countersinking, and ends with a thread for an M10 x 1.5 screw.

If anyone has an example that could help me correct what I've done, that would be a great help.
