This is a MK2.5S gcode, but it should run on a MK3 just fine (and a MMU unit as long as you remember to load-to-nozzle before printing, or you can add a Tc code to it near the top). You can adjust the temperature down if you need to, but I needed 275 to get good layer adhesion with my ASA. This file is setup for ASA but also: adds 100% infill + extra perimeters to the small arm, a brim for bed adhesion (very easy to remove for ASA), and adds a hole that seemed missing. I have found that the square nut is hard to get in place, but isn't really needed so I have not tried to fix this (you can still get the bolt to go through which is plenty of constraint, if anything I'd rather it pop off it there is that much force applied).
