Even after doing all the hardware and mechanical touch-ups, I was not getting great prints. This was solved by calibrating E-steps, as they were quite off (instead of extruding 100mm of filament, my printer extruded 95mm before calibration), so make sure you do that as well. -Instructions can be found here: +## PID Autotune using the menu: + +- PID Autotune: Go to Menu->Configuration->Advanced Settings->Temperature +- select PID Autotune E1, and set your printing temperature.
