The singular problem I have, in running linuxcnc on an armhf with a jessie install, is that in a data entry box of the axis interface, called the MDI, where single command lines of gcode can be entered and executed, on all the wheezy ia86-64 machines, I can run the cursor back and forth with the left-right arrow keys and edit the next command easily. On the armhf/jessie install on an rpi3b, the arrow keys do not work, so the mouse must be used very precisely to position the cursor for an edit. Its a small, 1 line box about 25 characters long. When the mouse is running in swarf (metal shavings) up to its ankle bones, making a smooth move that precisely is, shall we say pickity and time consuming? But get this, when I reported this problem to our developers mailing list, my 5 x86-64 machines that can do that, and have been doing it for a decade plus, are apparently the only 5 machines on the planet that can do it! It does not work on any of the developers own machines, and never has. The up-down arrows to scroll thru the history and call it back into the MDI box to re-execute it work perfectly. Go figure that one out. I'm running out of hair, and ways to mutter wth... :) The rpi3b may get replaced with a rock64 before too long, it claims it hasn't the i/o bottleneck the rpi's have, and which cause dropped key/mouse events. Thats very dangerous around machinery with the power to maim or kill. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
