The interpreter will not allow a command that is beyond the soft limit. The trajectory planner assures that there is (essentially) no overshoot of a commanded position. Therefore, there is no need to have a slow zone.
If, on the other hand, the software is not trustworthy, hardware limit switches will solve the problem. Unfortunately, they must be located such that at maximum velocity the machine will be able to stop prior to damaging itself. Of course, there are plenty of other ways for the machine to crash. Not all are preventable by hardware. Some are difficult for software to handle. For example, the software does not model the vise and fixtures.

I would like to see slow down spans at the end of the table travels. This would be a user configurable distance to slow down the axis travel when it approaches the soft limit of the axis travel. Both rapid and feed motion would slow down in this area to make sure there would be no overrun past the soft limit. It would allow full interpolation and motion in this area. thanks Stuart ------------------------------------------------------------------------- Take Surveys. Earn Cash.
