I have, that kernel has a bug though, as booted the keyboard repeat is several hundred a second, so its best you open the keyboard/mouse configurator, and slow it down to less than 20, else the repeats flood overload the pi's input and keyup events get thrown into the bit bucket and missed. Bad form if the keyup missed is a jog key. I've broken several hundred in carbide chip tooling because I wasn't fast enough on the double tap to get it stopped before it hit the workpiece or something and shattered like glass. But I put mpja jog dials on the apron and their data goes in thru the 7i90 and gpio, works perfectly. > Of course a complete image would be great. The initial configurators will get you to a basic working condition in an hour or less from ejecting the dvd and rebooting after the install. Anything else for eye candy or convenience is up to you to borrow from us or compose on your own. Each of us has his own ideas as to whats important. I have an added spindle tach and rigid tap overshoot displays on those machines that can rigid tap for instance. > _______________________________________________ > Emc-users mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/emc-users Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
