These are the axis "soft" limits. You normally set them relative to the absolute $home of an axis (g53 measurements) to prevent its running into the mechanical limits, usually I set them about 25 thou off the crash points for each axis. When software stepping, they are stepgen.N.min_limit and stepgen.N.max_limit. But there are no such critters in the 5i25 stepgen's. It apparently depends on axis to set and enforce those, and I hadn't noticed they were missing in the hal files I've hand carved previously. So now I think I understand how they work, but it was a surprise when setting it, that hal said it was no longer present, so I couldn't setp it. Panic time till I figured it out. :) Tomorrow, since I'm waiting yet on a slow junk from China, I'll cut up some cable and see if I can get it to run the vfd with the 7i76 spindle controls. I think I'll need 5 conductors so I should be able to do it in one 5 pin connector, if the pot common is also the ground reference for spinena and spindir. Most of the vfd's I've had, (a sample of one, which I'm running with a spinx1) share that. That I haven't verified with a meter yet on this vfd... I did get the imitation Renishaw yesterday, and I certainly can't wax poetic about it. Very poorly made IMO.
