¶ 2) Excessive speed causing layer lines
Please try adjusting the print parameters. It is recommended to increase the lift distance and decrease the lift speed and retract speed while keeping the existing parameters.
¶ 3) Sticking of lead screw or guide rails
If the printer has been in use for a while and layer lines consistently appear at the same height during multiple prints, it is recommended to clean the lead screw motor and linear guide rails with a lint-free cloth.
Note: Do not use alcohol or water for cleaning to avoid rust or seizure of the lead screw motor. Avoid using lubricating oil as much as possible, as it can flow into the motor along the lead screw and damage the internal structure. After wiping with a lint-free cloth, apply lubricating grease to the lead screw motor and linear guide rails, and perform multiple up and down movements to ensure even distribution of the grease.
