Thorleif,
Machines are different so pix are probably not all that useful.
I'll ponder a bit more about this, may use a movable cam instead and
leave this switch fixed like the rest of them.
Thanks

My Denford mill has an easily adjustable Z switch - very simple
mechanics. I can upload a picture if you have a hard time figuring out
how to implement it.
Often the part is held by a vice and far above the plane. Also most
of
my tools are almost equal in length, so it's relatively easy to set a
relevant negative Z limit. I have never needed it so far, but one day
I'll thank Denford.....

Well, on this machine its not a problem because the spindle itself
(no
toolholder) stops at the table, and
it the table wasn't there the spindle could go a further 10-15cm
down.
However the table
can not be moved sufficiently X-Y for that to happen. So Z can reach
the
table even without any tool.
So wherever I'd place that switch it would either allow a mech.
crash
with the table, or with a shorter
tool there wouldn't be sufficient Z travel towards the table. Either
way
the limitswitch would just be a nuisance.
Only solution I can see is if that switch was adjustable so it could
be
adjusted to match the length of the tool
in use at the time. Probably not too practical with an automatic
toolchanger, but I'll be using manual toolchange
so this might be a way forward.
I believe there are plenty of 'cnc-millers' on this list and they
must
have run into this problem and possibly solved it.
I could go for a movable switch right now but would like to avoid it
if
possible...tricky mechanics.
Would like some more input on this problem.
Thanks

How about if your tools too short and then you will stress out
some
mechanical part trying to go further down than it can.
This assumes you have soft limits out of wack.
Thanks,
Lee.

before the toolholder hits the table.all you lose is an endmill
