I've been told that the auto load is only set on a fresh install of 3.2, as in going from 3.1.1 to 3.2. If a previous beta had been installed it would need to be loaded manually. @JayJay what version were you on previous to 3.2?
I removed that and changed it to single G30 command on its own and now it completes the G32 action with no errors, I dont know why it works fine on my Duet-2 with the S-3 switch in my homeall but the mini 5 doesnt like it
Perhaps your Duet 2 is running old firmware that doesn't support the S3 parameter?
The Duet-2 was/is on Release 3.2-RC1
And to confirm
Duet-2 WOULD complete the action with G30 S-3
Duet-3 Mini-5+ WOULD NOT complete the action G30 S-3
The Mini-5+ would only complete after i removed the S-3 switch
