Extruder Preparation Settings

How can I get my prints to extrude that little line at the front of the print bed *prior* to printing the skirt to get the extruder primed?

I'm trying to use Slic3r and for the life of me I can't figure out the start G-code I would need to set that up.

Thanks in advance.

Re: Extruder Preparation Settings

Any reason you're not using the settings provided by Prusa?

Anyway, this is the default start Gcode:


M115 U3.0.9 ; tell printer latest fw version
M83 ; extruder relative mode
M104 S[first_layer_temperature] ; set extruder temp
M140 S[first_layer_bed_temperature] ; set bed temp
M190 S[first_layer_bed_temperature] ; wait for bed temp
M109 S[first_layer_temperature] ; wait for extruder temp
G28 W ; home all without mesh bed level
G80 ; mesh bed leveling
G1 Y-3.0 F1000.0 ; go outside pritn area
G1 X60.0 E9.0 F1000.0 ; intro line
G1 X100.0 E12.5 F1000.0 ; intro line

I loaded up the one that came as part of their driver package, but it didn't seem to load anything beyond this as starting G-Code:

G28 ; home all axes
G1 Z5 F5000 ; lift nozzle

Now I just noticed it added a start menu entry that appears to load it up w/ the correct settings.

Thanks for finding those results for me. I'd tried googling it and didn't wind up finding the code I was looking for. What search terms did you use, so I know how to locate this better for myself next time?

I copied and pasted from my settings in Slic3r.

But, you can find all the settings in their most recent version here: https://github.com/prusa3d/Slic3r-settings/tree/master/Slic3r%20settings%20MK2
