Can't find setting in Merlin code

[PickyBiker]

I have made several adjustments in the configuration.h file to suit my custom 3D printer, but there is a setting that needs to change that I can't find. After homing all axis the extruder then moves out in the X direction about 40 mm. I need to change that to about 15 mm but I can't find that setting in the configuration.h file. Can someone please tell me where that setting is?

Do you mean when the print starts? When the extruder moves off the platform to purge? Is so that is in the slicer script code

Where is the slicer script code? I am using MatterControl and MatterSlice.

No idea.. just know it is in the script tab of S3D.
From Simplified 3D for my printer
G28 ; home all axes
G1 Y50 Z0.3 F9600 ; move forward to avoid binder clips
G1 X205 Z10 ; move off platform
G1 Z0.4 ; position nozzle
G92 E0 ; zero extruder
G1 E25 F225 ; purge nozzle
G92 E0 ; zero extruder
G1 X190 Z0.1 E1.0 F1200 ; slow wipe
G1 X180 Z0.25 ; lift

I would assume if the software has a profile for your printer it is in that profile.. just guessing

Thanks, I'll see if I can find it.
