I've not seen a rotary that could not turn forever. Can you supply a URL to such a device? I can see both sides of the problem, but it would appear to be a complex fix to treat rotary's differently in the touch off, and would be subject to throwing away the residual error the planner now tracks. That would be a source of a residual error condition unless it was actually rehomed to a sensor. But how many of us even have a home switch on the A axis? We tend to lay a machinists level on the workpiece, run it till the bubble is centered, or if really finicky, matches the table error, and call it zero. I dare say we could count raised hands on our fingers & not need to remove our shoes. :) Or am I the odd man out here? It has happened before. :( Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
