Its my understanding 32s can potentially be set for 20 or 60 mills. Mine runs at 60. Check to see what interface card it has.

Not to mention the machines themselves. I have a problem with my 28 ASR where its printing accuracy is much less than my KSR, but it isn’t a range finder problem. Whatever it is, it might kill me to track it down. This hobby isn’t for the faint of heart!

I confirmed that the 32 worked with the IRL and the box. So I plugged the box into the URL-17 loop. The 32 ran open. I pulled the box on the bench several times and rang out the wiring with an ohmmeter.
