The digital pots do work OK for FRO and the like - IMO not enough pulses per rev for MPG jogging. Have a look at: http://www.contourdesign.com/shuttlepro/shuttlexpress.htm It is designed for video editing ($59.95 list in US). USB interface. I have it set up with the spring loaded shuttle ring for continuous jog (it will do different speeds depending on the distance you turn it) and the inner jog wheel does steps. First four buttons select X, Y, Z, A axes. Fifth button cycles the step size (in range 0.1" to 0.0001") Very intuitive and fast for setting up a machine. Not so good for manual machining like you might do with a calibrated 100 click Fanuc MPG. The "bad news" for this list is that it is on Mach3 ;=) I still have little Linux sys prog experience (and actually not much with USB on Windows) - but the default Windows driver sees it as a standard HID (vendor ID 0xB33, Product 0x32). The Ring value has a range on +/- 7 so gives quite sensitive continuous jog speed control. If someone made a HAL driver for it, it would, I think,be easy to plug into EMC2.
