I use Klipper and Fluidd. The start gcode calls on a macro in klipper and passes through the temps. The macro handles the rest. Good point on line width, I'll make sure to change it. Already disabled retract before outer wall and layer change. That said, I've found my issue. After checking e-steps calibration, I found that it extuded only 18mm instead of 50mm and was squeaking a lot. Turned out the extruder arm has a crack in it. Time for an upgrade.
