BLTouch and jerky X axis

[Ephesian]

Hello

I have installed a Geeetech BLTouch probe to my i3 Pro W, and everything works except when I do a G29 to do the Bed Levelling ( atm I am using 3 point to test) the Probe goes to the to the first point and takes a measurement, then when the printer tries to move to the second position the x axis jerks and judders ( see video ). I have searched high and low or an answer but cant find anything. Any Ideas or how I can debug

I enter via Repetier Host

G28
G29

The printer works fine without the probe.

I am using a mac, with Marlin Firmware 1.1.9.1 with the Geeetech config files modified. ( see configuration.h )
