Bed probing feed rates
To speed up the probing for a touch sensor, a &quot;High Speed&quot; option is available in Configuration_adv.h which is by default disabled (//#define BLTOUCH_HS_MODE) as not all printers/sensors are able to use this.
You can also increase the homing speeds in your Configuration.h file.
// Homing speeds (mm/min)
#define HOMING_FEEDRATE_XY (50*60)
#define HOMING_FEEDRATE_Z  (4*60)

.

..
.
// Feedrate (mm/min) for the first approach when double-probing (MULTIPLE_PROBING == 2)
#define Z_PROBE_SPEED_FAST HOMING_FEEDRATE_Z

// Feedrate (mm/min) for the &quot;accurate&quot; probe of each point
#define Z_PROBE_SPEED_SLOW (Z_PROBE_SPEED_FAST / 2)

However, you can simply speed up the movement between probe locations by setting the movement speed directly through G-code. The G29 code, used for automatic probing of the bed surface is described in &quot;G29 Auto Bed Leveling (Marlin - MK4duo)&quot;. The S parameter in G29 can be used to set the movement speed between probes, where the units are specified in &quot;units/min&quot;, e.g. mm/min.
Note that you potentially can change the Z-height for deployment:
/**
 * Z probes require clearance when deploying, stowing, and moving between
 * probe points to avoid hitting the bed and other hardware.
 * Servo-mounted probes require extra space for the arm to rotate.
 * Inductive probes need space to keep from triggering early.
 *
 * Use these settings to specify the distance (mm) to raise the probe (or
 * lower the bed). The values set here apply over and above any (negative)
 * probe Z Offset set with NOZZLE_TO_PROBE_OFFSET, M851, or the LCD.
 * Only integer values &gt;= 1 are valid here.
 *
 * Example: `M851 Z-5` with a CLEARANCE of 4  =&gt;  9mm from bed to nozzle.
 *     But: `M851 Z+1` with a CLEARANCE of 2  =&gt;  2mm from bed to nozzle.
