Sometimes if you feel the leveling effect is not good, please kindly follow the below steps to do some troubleshooting:
Step 1: Load the new firmware (the new firmware optimizes software and leveling)
Step 2: Reinstall the machine and adjust the structural parts of the machine. It may be loose during transportation or some details may have been overlooked. The leveling effect may not be good due to not being assembled properly, or the leveling may be repeated.
① Remove the PEI and tighten the fixing screws between the hot bed and the hot bed bracket. Looseness will affect the leveling.
②Adjust the parallelism of the X-axis to make it horizontal.
③Reinstall the z-axis screws, check whether the brass nut screws are loose, and reinstall
④Level it again and make sure the Z offset is set correctly (keep the distance between the nozzle and the platform a piece of A4 paper, about 0.2mm)
Note that the power level on the back of the machine cannot be adjusted at will. It needs to be adjusted to the voltage range of the corresponding country before turning on the machine.
The metal PEI board needs to be installed, otherwise the proximity switch cannot sense the metal and cannot be used normally.
