Switching from Cura to Prusa questions (LK5)  

Switching from Cura to Prusa questions (LK5)

Hey,

Two questions:

1. I am switching to Prusa from Cura. I have most things functioning well, except for first layer. I am new to this so hoping maybe someone here can help me understand what I need to do. 

My Cura slices work very well, however, when using my prusa slice with the same model my first layer comes out very poor. I think the issue is happening due to the extruder being slightly farther away from the bed when using the prusa profile. Would I just use z-offset to fix this?

2. Would it be a good idea to transfer my start/end g-code from my Cura profile to Prusa or just leave it as is? It's just the default that Cura has for my printer (LK5), which does not have an option on Prusa. Here is my code:
 

PRUSA:

Start

G28 ; home all axes
G1 Z5 F5000 ; lift nozzle
M413 S0 ; Disable power loss recovery

End:

M104 S0 ; turn off temperature
G28 X0  ; home X axis
M84     ; disable motors

CURA

Start:

; LONGER Start G-code
G21 ; metric values
G90 ; absolute positioning
M82 ; set extruder to absolute mode
M107 ; start with the fan off
G92 E0 ; Reset Extruder
G28 ; Home all axes
G1 Z2.0 F3000 ; Move Z Axis up little to prevent scratching of Heat Bed
G1 X0.1 Y20 Z0.3 F5000.0 ; Move to start position
G1 X0.1 Y200.0 Z0.3 F1500.0 E15 ; Draw the first line
G1 X0.4 Y200.0 Z0.3 F5000.0 ; Move to side a little
G1 X0.4 Y20 Z0.3 F1500.0 E30 ; Draw the second line
G92 E0 ; Reset Extruder
G1 Z2.0 F3000 ; Move Z Axis up little to prevent scratching of Heat Bed
G1 X5 Y20 Z0.3 F5000.0 ; Move over to prevent blob squish
M413 S0 ; Disable power loss recovery

End:

; LONGER End G-code
G91 ;Relative positioning
G1 E-2 F2700 ;Retract a bit
G1 E-2 Z0.2 F2400 ;Retract and raise Z
G1 X5 Y5 F3000 ;Wipe out
G1 Z10 ;Raise Z more
G90 ;Absolute positioning
G1 X0 Y{machine_depth} ;Present print
M106 S0 ;Turn-off fan
M104 S0 ;Turn-off hotend
M140 S0 ;Turn-off bed
M84 X Y E ;Disable all steppers but Z
