4.1 Clean the Dust Screen
Why
The dust in the air will adhere to its dust screen on both sides of the Dual
Extrusion Module in daily use. If not removed in time, the accumulated dust
may hinder heat dissipation and affect the working efficiency of the module.
When
At least once every two weeks.
How
1. Prepare the cleaning tool: a cotton swab (or tissues) and water;
2. Power off the machine and detach the Dual Extrusion Module from the
machine;
3. Moisten a cotton swab with water, and stick it inside the air inlet to clean the
dust screen until there is no dust or water.
The cotton swab is a single-use tool. If there is still dust remaining
on the dust screen after you clean it once, take a new cotton
swab and repeat Step 3 to clean it again.
