Underextrusion after updating to Cura 4

[cgchild 0]

I have enjoyed Cura, but a few months ago I updated to 4.x and then my profiles didn't work (they seemed to think the filament diameter was 2.85) so I remade them and everything was working fine. Now I have Cura on a new computer and the problem has resurfaced with the same profiles. I tried remaking everything with no luck and I have checked the filament diameters, material diameters, etc. and everything looks fine but my printer is massively under extruding, so I need help figuring it out. I know it is software side. Thanks.

Have you checked the machine definition? What printer do you have?

@johnse Yes it is correct, Creality Ender 3. I did a reinstall, printed with default settings and everything worked. I changes some settings, it went back to underextrusion. Tried going back to default and now that is under extruding where it was not before. It's like changing any of the settings changes the material diameter to 2.85 but I can't see it or change it 😞

I'm using an ultimaker 2 with a stock machine profile with cura 4.4 freshly installed and freshly updated firmware on the machine. My machine is also massively under extruding. Its like that either cura or the firmware thinks that i have an ultimaker 2+ machine even though I have selected ultimaker 2 in cura as my machine. There are some other strange problems in my setup also including that it is printing every other line for the bottom.

Did you follow a guide for extrusion calibration, set a new extrusion on Ender 3 and forgot to add the Cura Gcode fix for the extrusion?
