Limit switchs

Thank you for the answer. A good friend did most of the wiring for me. Some of the limits switches are wired NO and some are wired NC. So I will switch them to all NC.

# --- MAX-Z ---
net max-z <= hm2_5i25.0.7i77.0.0.input-04


So to reverse the pin. How?

Add _not at the end of the line.

That worked for my 7i96. I would think it's the same for all the combos. It will yell at you if it's wrong

# external input signals


# --- BOTH-HOME-X ---
net both-home-x <= hm2_5i25.0.7i77.0.0.input-01_not ?

That's all I had to do.

O.K. I am getting the same errors with the _not and without it. Now all the limit switches are wired NC. I checked the voltage at the 7i77 board. It is coming off the 12 volt supply but it is at 2 volts. I am using the bottom row. The 1st slot is empty. The X is at the 2nd slot and Y is at the 3rd slot, and the +Z is at the 4th, and the -Z is at the 5th slot. I am not completely lost.

Error
joint 0 on limit switch error
joint 1 on limit switch error
joint 2 on limit switch error

I believe you will need to get at least 5 volts there.
