Bug Description

Strange traverse path after G29 in the Cura start code.

Steps to Reproduce

1. Install BL Touch
2. Change start code in Cura.

I changed the start code in Cura to start always with G29 Auto Bed Leveling.

My start code:

G21 ; metric values G90 ; absolute positioning M82 ; set extruder to absolute mode M107 ; start with the fan off M190 S{material_bed_temperature_layer_0} ; preheat and wait for bed M109 S{material_print_temperature_layer_0} ; preheat and wait for hotend M300 S1000 P500 ; BEEP heating done G28 X0 Y10 Z0 ; move X/Y to min endstops G29 M501 M420 S1 ; enable mesh leveling G0 Z0.15 ; lift nozzle a bit G0 X2 ; move away from clips G92 E0 ; zero the extruded length G1 Y50 E25 F500 ; Extrude 25mm of filament in a 5cm line. G92 E0 ; zero the extruded length again G1 E-2 F500 ; Retract a little G1 Y120 F4000 ; Quickly wipe away from the filament line

Actual behavior:

After G29 auto bed leveling, the X axis moves from the far right to the far left and draws a purge line here over the entire Y length. The Y axis then moves to the middle of the heating bed and printing starts from there.
