Ender 3 + bltouch start g-code


I have a problem with the start-gcode included in the prusaslicer for my ender3 with a bltouch. Everything works and i really like the feature with partial warmup however on thing annoys me alot. After final heatup it primes the nozzle in the middle of the bed and then at the side of the bed. I would like it to position the head at the side of the bed when doing the final heatup and then prime the nozzle at the side of the printbed to avoid any primed filament in my prints.

This is my start gcode:

G90 ; use absolute coordinates

M83 ; extruder relative mode

M140 S{first_layer_bed_temperature[0]} ; set final bed temp

M104 S150 ; set temporary nozzle temp to prevent oozing during homing and auto bed leveling

G4 S10 ; allow partial nozzle warmupG28 ; home all axis

G29 ; auto bed levelling

G1 Z50 F240

G1 X2 Y10 F3000

M104 S{first_layer_temperature[0]} ; set final nozzle temp

M190 S{first_layer_bed_temperature[0]} ; wait for bed temp to stabilize

M109 S{first_layer_temperature[0]} ; wait for nozzle temp to stabilize

G1 Z0.28 F240

G92 E0G1 Y140 E10 F1500 ; prime the nozzle

G1 X2.3 F5000

G92 E0

G1 Y10 E10 F1200 ; prime the nozzle

G92 E0
