Greetings folks; Looking at man motion, I see that the axis."L".jog functions are quite well covered, particularly including the use of the inner, spin it with a finger type dials.
Once I get it figured out what this things actual output data format is, hopefully at least the spin dial can be fed directly to one of the other 3 encoders I can enable in the 7i90 config. So the inner dial seems self-explanatory as to how to hook it up. The outer dial OTOH, would demand some live math to arrive at the desired speed vs how far the outer dial is turned, which is a spring loaded to center, with about a 270 total degrees range, and which I believe may have under 5 speeds each way. First IIRC was 1x normal speed in the direction it was turned off center, and a full twist would run the tape to anyplace in a 10 minute interview in 30 seconds or so. For use with machinery, that offcenter value should approach a square law response with the first increment in the 1cm/minute range, up to MAXVEL for that axis for a full twist. This would tie up several gpio's I expect, but I'll still have around 30 left by the time I get the home switches wired up. How would this be handled in hal? lincurve for however many steps it outputs? So I expect I'll have some better data to ask questions about once I've decoded how this talked to the machines originally.
