Uncomment out enable bed leveling

Enelable bed leveling is the last line in my configuration g file..under that it says ; G29 S1
How would I turn bed leveling back on

[oliof]

@ziggymanpopo you would remove the semicolon to load a preexisting bed mesh., but I'd advise against running bed leveling (as well as the homing sequence that needs to run previous to bed leveling) directly from config.g -- imagine having a print left on the printer at power off and homing/bed leveling crashing into that (or, even more likely, a partial print after an emergency stop/ immediate halt).

Still foggy on what to do. There are two lines at the end of my config g file I remember someone having me turn off bed leveling when I installed the ball screw

1. What is g29 s1 for. And the ; isn't a prob i can remove that. Is my command for bed leveling in the wrong spot (end of config.g
   2 should it be in another file .. ??
2. So I believe G29 S1 is the command for bed leveling but above it,,it says (; Enable bed leveling) does that command need to be there along with G29 S1 ???? Sorry folks but I'm not a programmer so any insite would be greatly appreciated

@ziggymanpopo see https://docs.duet3d.com/en/User_manual/Reference/Gcodes#g29-mesh-bed-probe

G29 S1 Load the height map from file and activate mesh bed compensation. The default filename is as for S0 but a different filename can be specified using the P parameter.

So it loads a previously saved bed mesh, with the default name. It doesn’t ‘do’ a bed mesh. However, you’ll get a message that the Z datum hasn’t been set yet, as the axes haven’t been homed yet.

You don't want to load a mesh before the printer is homed. A better place to have G29 would be at the end of homeall if you want it active all the time, or in your start gcode after homing is complete so that it's enabled at the start of a print.
