Linear Move Exceeds Lower Limit

Your assumptions are correct for both the table and the block.

I have my machine configured for both and home on all axes.

If you are able a willing to attach your hal & ini files (and any other hal files you may being using) it may be possible to run a sim of your config.
BTW what version of Linuxcnc are you using ?

Out of frustration, I removed the o<word> declarations from the file and loaded the file as a normal g-code program. It worked correctly, start to finish. What ever was happening, mysteriously evaporated.

Thanks for your input and consideration.

Might have helped if you mentioned this to begin with. You really wasted a lot of people's time not giving the whole story.
