Help needed to get my 7i76E + 7i85S + 7i73 on my mill going.

You can change this line

		motor_speed_out = speeds[13] * (spindle_speed_in / speeds[i]);

to

		motor_speed_out = speeds[13] * (spindle_speed_in / speeds[i+1]);

That should give motor-out-speed of 1600 because it is based on max-rpm 2500.
As far as I can see, there is no support in the comp for using different max rpm.

You *can* do like this. But it is never good to interfere in someone's line of thought so if
Andy has a better idea then go for that.
1. Add a variable "double motor_max_speed;" where the other variables are declared.
2. Just above the motor_speed_out line

                if (motor_high)
                   motor_max_speed = 2500;
                else
                   motor_max_speed = 1450;
		motor_speed_out = motor_max_speed * (spindle_speed_in / speeds[i+1]);

This should give about 928 rpm on motor. Assuming 125 spindle rpm at 1450 motor rpm.

Halcompile and all that to test again.

For the vfd speed, does it need rpm or rps (minutes vs seconds)?

omponent GB_2speed;

pin in bit spindle-enable-in;
pin out bit spindle-enable-out;
pin in float spindle-speed-in;
pin out float motor-speed-out;

pin in bit gear-high;

pin out unsigned gear-required;
pin out bit message-##[14];

I know, but there is no code to set different max speeds when the pin is high or low.
I added that code.
