That looks as if it could be modified to handle s32's, rebuilt & installed. But Kurt sent me a mux2 source that handles s32's, it built and installed once I had undone the line wrap damage email did to it, so I believe it might be the magic twanger I need. My coffee hasn't kicked in yet, but I should know in a couple hours when it does. Thanks jon. Secondary Q, for whoever knows: I am being plagued with joint following errors, even for tiny movements, smaller than the error tolerances set in the .ini file.. Is a limit3 limiting the acceleration the fix for that? Related Q: Is there an accel limit in the .ini file that applies to a jog-count or jog-scale input? Or are the jog-inputs movements limited only by the axis MAX_VEL? In which case I'd need a limit3's Alimit, loaded by one of the max_vel's from the ini file? Coffee still hasn't gone to work yet. But I made a fresh pot and I'd better see what my lady wants for breakfast. Thanks everybody.
