Oh… on settings, for me the generic profile has been great. The generic profile will have a higher nozzle temp but a lower bed temp.
You might be able to run a max flow volume test and tweak the volumetric flow, or other tests like retraction and temp towers, but largely the profile just worked for me. I’ve used XVICO, Bambu, and Polymaker PETGs and all print fine with the generic profile, with Bambu’s printing fine with faster profile settings as well. I did feel like the Polymaker was at its speed limit on the generic profile, but the others seemed to be comfortably printing along. Note, I’ve only printed black and clear PETGs.
