I print a lot with PETG and one of the things I notice pretty often is big blobs of material where the path ends and the printer retracts. What I believe is happening is because the printer is continually extruding until the end of the path the excess pressure in the bowden tube is continuing to extruding while paused/retracting. I've messed with coasting but it usually seems to cause more problems than it solves. Is there a way to begin retracting before the nozzle reaches the end of the path? I haven't found a setting in Cura but maybe someone has a macro or other fix for this?

I should clarify that I am creating my own profiles regardless, I am not using the standard Ultimaker Profiles. That said others in my organization are also using the profiles that I develop and as such it would be nice if the material selected in Cura could match the profile. For example, we print a lot with PTEG but the Generic PETG profile in Cura is disabled for the UM2+ so we pick CPE instead and use a custom profile named "PETG-0.4mm Nozzle-0.2mm Layers". It's less about using the specific material profiles and more about the user being able to pick the correct material in Cura for the custom profile I have created. Does that make sense? All the materials "unlock" if I create a "Custom FFF printer" but then I loose the ability to pick nozzle size from a dropdown list.

Is there a way to "unblock" all materials in Cura? We have several Ultimaker 2+ printers that we have modified with Bondtec extruders, magnetic build plates and aftermarket nozzles specifically to print "non-standard" materials. We still use Cura for slicing but the default Ultimaker 2+ machine profile has a number of materials disabled. We run custom profiles so it's not that big of a deal but materials like Generic PETG and a number of other materials from the marketplace are disabled. I've tried creating a custom machine with the same specs as the UM2+ but by doing that I loose the nozzle size selection.
