Just discovered that manual "Override limits" does not work. Red led flashes, I push a Reset button, but I can't jog out of the switch. The same time AutoOverride Limits works well, homing works well, limit switches themselves works well. Everything, concerning a limit switches, works well, except of a manual Override limits. Does it relates somewhere to SS?

Not sure, I always have Auto enabled.  If no one else comes back with an answer I will try and remember to test tomorrow if I get back to the workshop in time, if not it will be Saturday.

It works but it's funky.  You have tho click the reset button 2 times.  Then it should allow you to move off your limit switch.

Today I have tried this with PP version and manual limits override works well.
