Does this mean what I think it does, that you can already arrange within EMC
for the HOME position to need both a limit switch set and a pulse on the
axis to believe that the machine has truly homed? I had been thinking of
having to produce a set of little logic boards to AND the limit switch and
the signal to one coil of the motor together to get a reliable HOME
position. Will it work for all axes and with steppermod or frequmod?
Thanks,

Ian
