There is a possibility to "overrun" the axis velocity limit and have it continue to move when you stop cranking. If you quickly crank back you can stop the axis. Once you have experienced this, you learn how fast to crank. I have the hal files set up to require a button being pushed to enable the encoder to drive the axis. So, cranking the dial when the button is NOT pushed has NO effect. I think this is a lot safer, as I have bumped the dial many times when setting up, and am glad it did not cause machine movement. See the file : configs/by_interface/pico/univpwmv/pendant.hal
These encoders will give 400 counts/rev in quadrature, so there are some scale factors to make the dial graduations come out right. That file doesn't have the extra lines to control spindle override and feedrate override, which I now have. Also, the ilowpass is a custom component that smooths the integer encoder counts so it doesn't buzz the servos.
