Nope, you are looking at the new_pncconf branch :)

Don't press the calculate button, just enter the scale in the spinbox beside it.

Pncconf was not made with converting configs in mind, so usually there is no HAL
file to look into and it also doesn't look in the INI file either.

This is loaded in the HAL file by a line similar to this:
loadrt hm2_pci config=" num_encoders=6 num_pwmgens=0 num_stepgens=0"
This particular line says:
enable 6 encoders, (so if the firmware defines 10 the rest after 6 would be
GPIO)
enable none of the PWM (so all the pins are GPIO)
enable none of the step gens (so all the pins are GPIO)
