Good afternoon folks.. Just FYI, i was a busy member on this forum for a long time.. I havent done much printing lately, but now i need to

something strange happened earlier, where my ABL plunger now is about 7 degrees offset so the corner of the plunger hits instead of the trigger, then just plows in to the glass of course.

I know i need to change someone in the configuration.h i presume? problem is, i havent done it in a year.
Can i read from the configuration.h and just append to it? which value am I changing? it was set to 93 in my macro test, now its 85 (thats the one that works)
the macro code line is
M280 P0 S85

I just dont know how, or where to change it.
I dont have a configuration.h anywhere handy that I know was the one i used, so i would lose all my settings if i just took a new random one.

thoughts? help? kind of desperate here
