Printing with 2 Skirts

Hi there everybody.
I've been trying out the new dual extrusion settings and was going to use two skirts as a way to simulate a purge wall. Unfortunately, I've added a skit to each process (two processes for the two models, one for each color/extruder) and the visualizer (and my test prints) show only one is being generated. I've offset the skirts, and made one two outlines thick for clarity, but only the first one is generated. I even grabbed the factory files of an old post that claimed to have done it, but that one also only generated one skirt. It seems that the new update has removed this functionality. Can anyone advise me as to how work around it? Thanks very much! I've attached the factory file of what I was working on.

Using the tool-change scripts they added, especially with the IF statements I've been printing using the tool-change scripts in the Factory File attached. This will create one skirt, but that skirt will use both extruders as needed! :D

Re: Printing with 2 Skirts

Wow! I didn't realize that Simplify could use IF statements in the gcode writer. What else don't I know?! Are there other variables, etc? I know about the temperature, that's it.
I only took a quick look at your code, and I'm away from my printer, so I may be wrong but: Wouldn't it execute twice at the same level (once for each tool change), and try to print over itself, thus not purging the second tool properly? I mean, it's easy enough to tell the it to draw a different path when switching to the second extruder, now that I know about the if statements (or have each only do half of the skirt). Also, I wonder if there is a way to make it travel a dynamic amount, so it could auto-resize the skirt, instead of editing it for each print.

Thanks very much KeyboardWarrior, I've got some new stuff to play with! :D

Re: Printing with 2 Skirts

Ok, Now that I've actually tried it I ran into a few problems. The first is that the first tool always has trouble laying down it's first purge because it doesn't adhere well. I could always slow it down, but that would slow down all of the purges in the print, which is less than ideal. Is there anyway to tell it to slow down only on the first layer (since it doesn't seem to take into account the first layer speed percentage).

Also, my visualizer shows that the first tool is purging in the air, whereas the second tool is purging on the bed for their first layers. This broke my idea that I could just include a first purge in the start gcode to let the rest of the purges adhere well (even if the first ones would overlap the one I put in the start Gcode).

I'm still wondering about using the skirts. Has anyone figured that out?
