Ya I should’ve been more specific. In my case, it was the EEPROMS U20 & U21 on the MLB3’s CPU. Still have them archived so was able to check. I want to say it was MCSS parameter Velocity Normal that kept changing to a huge number. All other parameters were fine so after copying to new chips we could set it to the right value.
Sounds to me like you have an EEPROM problem too. Could be OCSS or MCSS depending on which parameters you aren’t able to change.
