You know, I hadn't thought about this. The original design for spindle-synced motion was when we had single precision floating point positions, which get really ... (what's the opposite of smooth?) crunchy when you get far away from zero. Resetting after the spindle was perhaps running at 10krpm for while before you tap was a VERY important thing to do. We now have double precision floating point for hal floats, so I think the consideration is gone or mostly gone, but a spindle could conceivably run fast and for a LONG time in one linuxcnc session (weeks? months?) and always in the same direction. I wonder how long you'd have to run before orient (which doesn't reset, with the current design) works badly...? ------------------------------------------------------------------------------ Monitor Your Dynamic Infrastructure at Any Scale With Datadog!
