How to troubleshoot grind on rotary pump

I have read that on vib pump machine, having a brew pressure of 1 is a rough guide to correct grind size. I have a rotary pump machine and the pressure is always at 1. How to use the above principle to troubleshoot grind size?

Best use that principle to obtain some training. The number 1 has nothing whatsoever to do with brew pressure!

Sounds like a boiler pressure reading as 1.0 - 1.2 ATA is very common.

I have often found myself wondering about the best grind size to use with a 240 volt espresso machine
