gearchange

Damn, still a lot to learn.

Thanks!

I have a lathe with a 9-speed gearbox that is manually selected. The motor is always running at its maximum speed of 1360 RPM, and the speed is manually changed using the gears. I'm using your gearchange component, which supports up to 32 speeds. I've already implemented the logic to select each speed. In each range, I'll control the speed with a VFD between the lowest value of the previous speed and the maximum, according to the original lathe's speed chart. For example, the first speed is 36 RPM, the second is 90 RPM, and the third is 155 RPM. Then, in the first speed, the spindle would rotate between 0 and 36 RPM, and the motor would rotate between 0 and 1360 RPM. In the second speed, between 36 RPM and 90 RPM, the motor would rotate in that gear between the speed that the gear provides, resulting in 36 RPM and 90 RPM at the spindle. This pattern is repeated for the other speeds. My question regarding this component is how to adjust the scale on each device; I don't know if it's always done relative to the first one or relative to the previous one.
