Can't get M505 to work
-
I'm in the process of converting my printer to use servomotors in the XY stage instead of steppers. I tried to use M505/M98 to switch to a new config file for the servos, but it seems the config.g file is not being read or the M505 command is not being read from the new location. The networking never becomes active, etc.
Here's the root folder on the uSD card:
In the sys folder I have nothing but a config.g file like this:
;M505 P"step" M505 P"servo" M98 P"config.g"In the /sys/servo/ folder I have
The /sys/step/ folder has all the same files, except the config.g files in those two folders are slightly different.
/sys/step/config.g looks like this:

I copied the contents of the /sys/step/folder back into the /sys/ folder and it worked fine. So it looks like the controller is either not reading the config.g file in the /sys/ folder or is ignoring the M505 command.
In the M505 entry on the wicki here it shows M98 P"config.g" with some sort of tiny character following the final ". I tried using a ' but it doesn't work with or without it- typo?
Any ideas?
Thanks!

@mrehorstdmd The directories servo and step need to be in /sys.
From the M505 description:
M505 P"experimental" ; change config file path from /sys/ to /sys/experimental/``` -
@stephen6309 Doh! Of course! Thanks!
