I'm at the latest version now.

$ rancid -V
rancid 3.5.1

$ cat ~/.cloginrc
add autoenable supermicro-switch 1
add user       supermicro-switch username
add password   supermicro-switch password password
add method     supermicro-switch ssh

Created smlogin based on blogin so `smlogin -c"show version"
supermicro-switch` runs fine:

$ diff usr/libexec/rancid/blogin usr/libexec/rancid/smlogin
501c501
<     send "more off\r"
---
>     send "no cli pagination\r"

Now, most of the posts suggest that the reason for getting "End of run not
found" is that rancid does not recognize
when the session to the switch is terminated. On Supermicro that seems to
be "supermicro-switch#exit".

I'm trying to find out the workflow of rancid in order to make the
adjustments:

$ grep '#exit\$' usr/share/perl5/vendor_perl/rancid/*
usr/share/perl5/vendor_perl/rancid/edgemax.pm:    if (/\#exit$/) {
usr/share/perl5/vendor_perl/rancid/foundry.pm:    if (/\#exit$/) {

$ grep '#exit\$' usr/libexec/rancid/*
usr/libexec/rancid/rrancid:    if (/\#exit$/) {

First question: what is the purpose of usr/libexec/rancid/rrancid compared
to the perl modules under usr/share/perl5/vendor_perl/rancid?

Second question - I'm doing:

$ cat etc/rancid/rancid.types.conf
supermicro;script;rrancid
supermicro;login;smlogin
supermicro;inloop;edgemax::inloop
supermicro;command;edgemax::ShowVersion;show version

but I can see that there seem to be no effect due to what I write for some
of these options, e.g. I can do without errors:
supermicro;script;dummy
supermicro;login;smlogin
supermicro;inloop;dummy::inloop

I would imagine something like that would be caught by rancid configuration
parser as incorrect and prevent the run?

Adding debug prints to the check for completness in
usr/libexec/rancid/rancid (also suggested in some posts) is not helpful:
printf(STDERR "$host: missed cmd(s): all commands\n");
printf(STDERR "$host: $clean_run\n");
printf(STDERR "$host: $found_end\n");

$ rancid -d -t supermicro supermicro-switch
loadtype: device type supermicro
loadtype: found device type supermicro in ./etc/rancid/rancid.types.conf
executing smlogin -t 90 -c"show version" supermicro-switch
supermicro-switch: missed cmd(s): all commands
supermicro-switch: 0
supermicro-switch: 0
supermicro-switch: End of run not found
