CNC mill tool changer

Thinking it would look something like this.?????????????

With power up program starts
Counts input pulses from (input pin2)
Also on first pulse waits for a 1 sec gap then stops counting
Unclamps tool in spindle (output pin6) leaving on
½ sec delay
Drops mag (output pin5)leaving on
1 sec delay
Rotates stepper motor till limit switch (input pin2)T1 position
Rotates stepper motor to position of tool called up ie 5 pulse = tool 5
(6400 steps per rev divided by 16 positions = 400steps per tool, T1=0, T5=2000).
Lift mag (output pin 5)by turning off
½ sec delay
Clamps tool (output pin 6) by turning off
½ sec delay
Sends cycle start pulse via (output pin 2) pulse
Loop back to waits for input pulses
