and I believe the "encoder" is metallic contacts. If you want a very controllable movement for jogging to a "touch", rather than one click is a thou, for manual machining it is worth looking at: http://www.contourdesign.com/shuttlepro/shuttlexpress.htm 5 buttons (axis selection?), a spring loaded ring with 7 steps each side of centre (continuous jog at 7 different speeds - make them geometric ratios), a centre "jog" wheel (coarse steps but fine for the last few thou). I removed my "real" MPG from a mill in preference for this $60 device . You can whip from and to end of end to end of an axis at full rapid but slow to a kissing touch with great safety. IMO a case of not having to emulate how handles connected to the old racks of TTL controlled machines :=) Not done it with EMC2, but device is a well behaved HID (Vendor Id 0x0B33, Product Id 0x33) so it might not be too hard. Don't bother with the driver that comes with it (Win only I think anyhow). I would send someone $60 to buy a wheel if that got us a HAL module for it (seriously). John Prentice ps its brother Shuttle Pro has more buttons but I don't think I would remember which does what and no easy way to label them :=) ------------------------------------------------------------------------- Take Surveys.
