;
; ========== Cura Start ==========
;
; ---------- Standards and safety ----------
G21                         ; Units in mm
G90                         ; Absolute positioning
M82                         ; Absolute extrusion mode, matches Cura default
M107                        ; Fan off
G92 E0                      ; Reset extruder

; ---------- Heat strategy ----------
M140 S{material_bed_temperature_layer_0}           ; Start heating bed
M104 S150                                          ; Preheat nozzle to 150 C to reduce ooze during probing
M190 S{material_bed_temperature_layer_0}           ; Wait for bed
; Optional soak to reduce thermal drift on mesh
G4 S10                                             ; 10 second bed soak

; ---------- Homing and leveling ----------
G28                                               ; Home all axes
; If you keep a stored mesh and want faster starts, use the next 2 lines instead of G29:
; M420 S1                                          ; Enable saved mesh from EEPROM
; M420 Z{0.2}                                      ; Apply z fade height, adjust to taste
G28
G29                                               ; Live mesh with BLTouch
G92 E0                                            ; Reset extruder again after probing travel

; ---------- Final nozzle heat ----------
M104 S{material_print_temperature_layer_0}         ; Bring nozzle to print temp
; Move near prime location while heating
G1 X2.0 Y10 Z5.0 F6000
M109 S{material_print_temperature_layer_0}         ; Wait for nozzle

; ---------- Prime lines, sized to bed ----------
; Use relative extrusion for priming so we can reason in mm of filament
M83                                               ; Relative extrusion
G1 Z0.3 F3000
G1 X2.0  Y20   F5000
G1 X2.0  Y{machine_depth - 10}   F1500  E15       ; First long prime line
G1 X4.5  Y{machine_depth - 10}   F5000            ; Shift over
G1 X4.5  Y20                 F1500  E15           ; Second line back
G92 E0                                            ; Zero extruder after prime
M82                                               ; Return to absolute extrusion for print moves
G1 Z2.0 F3000                                     ; Lift to avoid scuffing
; Optional wipe move toward skirt start
; G1 X{skirt_brim_minimal_length} Y20 F5000

; ---------- Optional per material tuning ----------
; M204 P{machine_acceleration} T{machine_travel_speed}    ; Use if you manage accel per material
; M205 X10 Y10 Z0.4 E5                                    ; Jerk and junction settings, Marlin specific
; M900 K{material_linear_advance_factor}                  ; Linear advance if enabled in firmware

; Hand off to slicer generated G-code

; ========== Cura End ==========
;
; ---------- Finish buffered moves ----------
M400                         ; Ensure all moves are done

; ---------- Controlled retract and lift ----------
G91                          ; Relative positioning
M83                          ; Relative extrusion for the retraction
G1 E-1.5 F3000               ; Small direct drive retract to relieve pressure
G1 Z10 F3000                 ; Lift Z to clear the print
G1 X5 Y5 F6000               ; Short wipe away from the part
M82                          ; Back to absolute extrusion mode
G90                          ; Absolute positioning

; ---------- Park and present ----------
G1 X0 Y{machine_depth} F9000 ; Park at front for easy removal
M106 S0                      ; Fan off

; ---------- Cooldown ----------
M104 S0                      ; Hotend off
M140 S0                      ; Bed off

; ---------- Steppers ----------
M84 X Y E                    ; Disable X, Y, E, keep Z energized to avoid drop
; M84                         ; If your Z cannot drop, use this to disable all axes
