How to swap out arduino

[aluminumwelder]

.ini file complete save?

Just want to double check before I tweak settings. Does the ini file contain ALL the settings and if I change settings including running triangular calibrations will everything revert if I decide to restore a backed up ini file? Are none of the settings retained on the arduino? Just want to check before I change anything, my settings are the best they’ve been so far so I’d rather leave them if theres a risk of making wrong changes… but we are tinkerers after all. lol

above thread says to erase arduino, to force it to update?
