Machine Limits

[Bucko911]

I can't seem to get my machine limits to save. They save just fine during a work session, but when I restart the software all the machine limits are gone and I have to reset them. Is this normal behaviour or am I missing something?

Actually, if you have limits set up, it's "normal" practice is to reference the machine every time you start it up to "home" the machine to a known position. This way your limits are always in the same place.

With that said, some do not use limit switches at all and just "zero" the machine where they would like it to be zero'd using a reference point on the material or table for each job.  This means you would not set up any limit switch settings in Mach 3 and then when "Ref all" is hit, it just zeros the position in the current location.
