Fixes
-
Take out the build plate and check the four screws in the top and bottom of the heated plate are tight. You will need to put a 2.5mm wrench in both the top screw and the bottom screw at the same time, and turn them against each other until hand-tight.
- Make sure that the printer is placed in a stable position and does not shake. You can also restart the printer power, place the printer on the ground for automatic leveling calibration, and check whether the same error still occurs.
- Turn off the printer power and remove the heated bed. Find the pressure sensor adapter board. Then replug the four pressure sensor plug. Refer to the video below, the time nodes of the operation steps are 00:00-01:28: https://www.youtube.com/watch?v=_s9hSNidf54
The following photos compare some common poor plug contact situations with normal situations.
After completing this step, please install the heated bed support, springs and other accessories to their original positions. Then re-calibrate the automatic leveling.
