Revo 6 with Bobstro's Starting G-code

As per the E3D guidelines, I added an 18mm retraction in my end G-code to facilitate faster nozzle swaps. How do I go about reversing this in Bobstro's start G-code, he has already modified the purge line so I am not entirely sure where to account for the additional 18mm retraction. 

my guess is changing this line 

G1 E2 F1000 ; de-retract and push ooze

from E2 to E20 ??

 

Thoughts ?

Yes.  As long as there isnt any other code in your startup that already pushes out filament.

I decided to do this instead, add 6 mm to each of the intro line components in bobstro's code.

G1 X26.0 E6  F1000.0 ; fat 26mm intro line @ 0.30
G1 X66.0 E3.2  F1000.0 ; thin +46mm intro line @ 0.08
G1 X106.0 E6  F1000.0 ; fat +46mm intro line @ 0.15

The other way created a massive blob in the beginning when I had cancelled a print and it never retracted. This puts it into the prime line and won't be a big deal if I dont get the retract done at the end of a print.

And that sounds like a sensible work around to cope with cancelled prints. Nice idea.

RE:

I can't seem to edit my reply, here is the actual code, that one posted above is incorrect, the e-values were adjusted here to add 6mm x 3 of extrusion to the prime line  to compensate for the 18mm retraction

 

G1 X26.0 E12  F1000.0 ; fat 20mm intro line @ 0.30
G1 X66.0 E9.2  F1000.0 ; thin +40mm intro line @ 0.08
G1 X106.0 E12  F1000.0 ; fat +40mm intro line @ 0.15
