Hi

I am trying to figure out how to fix an issue i got when trying to print using both extruder using the Dual extruder module.
See picture of the issue. It seems to push down small amount of filament.
Any idea ?

It’s too near to the bed. Adjust the live z offset on the touchscreen by swiping left to z offset.

At least is it the case for the blue extruder. It’s causing over extrusion for a few layers.
