Troubleshooting

Problem: Consistent Inconsistent Layer Lines. I am getting very consistent lines that bulge out repeatedly every print.

Solution: I found that my flow rate was too high. By printing more calibration cubes and following both Ellis3dp and Teaching Tech's extrusion multiplier tuning guides, I was able to find an ideal extrusion multiplier value of 90%. This drastically reduced the consistent inconsistent layer lines. 

Problem: My Z axis isn't moving the full 10 mm its supposed to. It's moving slightly below at about 8.25 mm. My rotation distance in Klipper is 4 and full steps per rotation is 200. According to my research, the Ender 5 plus has a T8-2 lead screw. 

Solution: When using sensorless homing, you lose steps because a mechanical component on your machine is ramming into the side of the printer. When the printer detects a higher amperage, the printer knows you've hit the mechanical limit and stops the stepper motors from spinning. 

In the case of my printer, the bed is mounted to aluminum brackets where leadscrews raise and lower the bed from the middle while being constrained by linear bearings at the ends of the brackets. What would happen is the leadscrews would continue to spin when the linear bearings had stopped at their physical limit, causing the aluminum brackets to bow. Since the linear bearings are so far from the center where the lead screw is, the sensorless homing threshold would only be reached once a certain level of bowing in the aluminum brackets occurred. I switched to an inductive probe and this solved my problem.
