hello,
i'm trying to use servo
i configured everything like offsets from extruder, probing points,
when i give G29 command
servo extends and then probes to first point, and then it doesnt retract and keeps moving from one point to another
i want to retract my servo at every probing point so i can avoid any crash.
please help,

my servo doesnt retract like it happens in this video [www.youtube.com]

It depends on which auto bed leveling you are using... But you can usually specify an 'E' option to engage and dis-engage the Z-Probe.

But really... You typically get better measurements if you leave the probe deployed. You are better off setting the various numbers better.

#define Z_CLEARANCE_DEPLOY_PROBE

#define Z_CLEARANCE_BETWEEN_PROBES

Leave it down to probe all the points, its more accurate that way.

I had all kinds of challenges with the latest Marlin firmware getting this to work. I then loaded V1.1.0 RC8 and now everything works a charm. Might want to give that a try.
