So I was having some issues with the dual prints on the taz with slic3r because when a print finished one would be retracted slightly if it wasn’t the last one to print the part. So I have a flexible dually on a Taz 6 that now automatically does all of my awesome start and end gcodes in slic3r so that I don’t ever have to worry about my prints getting messed up. It has the heating of BOTH tips put into the gcode, funny comments on the screen while doing it, and you will never have to worry about the retraction being to far back when you begin a new print. These presets are for PVA and PET-G But it’s set up in a way that doing things with ninjaflex is also very easy just change the 190 temp for PVA up to 210 for ninja flex. and I would absolutely recommend everyone to use slic3r for dual prints over cura, slic3r has way more options in the “settings” in the top row next to ‘split’ and ‘cut’. Right now since PVA is more $$ I have it print PVA only where the supports meet the part so it has all of the same benefits but with none of the large amounts of wasted expensive material.
I have a file attached to this post but I’m also going to paste the code into here since it isn’t THAT much code to work with
