I'm pretty sure no. I thought the machine I have using CL uses several more
than 2 compares, but I'll have to check (it was several years ago I wrote that
ladder.)

Oh I misunderstood your question. Yes I think a single variable comparison
block is limited to only a single comparison of a variable to one constant or
another variable. I am surprised that it worked with the last two compares
combined into a single block. So for your row of logic below I
The CL program I have running on our machine has at least 20 different variable
comparisons. There are even 6 in a single rung with 4 or branches and 2 pairs
anded together. So yes you can use more than two, and as far as I know there
is no practical limit.

In the manual - they say you can 'and' and 'or' and such.. You need a ,
then the operator.. But I think maybe the limit is 2..

is possible I was missing the key "," in the phrase (it was a long time ago.)

know the little nuances - it is pretty cool!

the comma certainly tripped me up.. This isn't my first or even most
complicated ladder - but buy - it has been a few years. Have to re-learn
it all over.

Mine are all permanently mounted, as a proper tool height setter should be.

My tool height sensor arrived today. Needless to say I dropped everything
(almost) to play with it. Nicely sensitive. Good over travel before NC sensor
opens so that second switch could be in series with Z axis limit.

A few photos of your mounted setup would be really helpful. If you can't post
them to the list just pm me.
Thanks
