Geeetech i3 Pro W Calibration/Extrusion issues

[jingsani]

This printer has been a pain in the neck for nearly a year, to the point where I had to use a second printer to print a fix for the Z axis binding and update an option in the firmware to get the travel on said https://9apps.ooo/ Z axis correct. Since then I've had quality issues, I'll link the imgur album showing two battery cases I've tried to print that show under extrusion that I'm not sure how to fix as well as a benchy that I have no clue what's wrong with it. I should be able to provide the applicable Cura settings, they're both printed in 3D Solutech PLA at 200c with 60c bed temp (no adhesion issues).
