UM2 Default Material feed percentage

Was trolling through the "Tune" options during a print and noticed that the "Material Feed" percentage was defaulting to 107%.

Has anyone else ever seen this with a new machine? I upgraded the firmware immediately after setting up the printer.

I think its the case for the ABS material preset.

Nice to know. When I first started printing with ABS I thought I was getting over-extrusion on the first few layers as the print head.seemed to be ploughing through ridges of material from adjacent passes. Went away after a few layers so could have just been my build platform being a calibrated a little too close.

Going to run Triffid Hunters calibration tests to see how my printer fares in stock settings. Am getting some pillowing on the top most layers when I printed Coffins Cube so need to look at the fan settings and experiment with temperature. In general, I feel I am getting poor bridiging performance so hopefully that will help.
