The petg extrusion multiplier is 1, the line width of the first layer is 0.45mm, and the line spacin
How to adjust? Continue to increase the line width of the first layer?

before you tune the first layer you need to tune your EM, 1.0 is way too high, once tuned you can tune the first layer

If it is lower, the line spacing will be larger
you fiorst need to tune your em, after that the first layer

This is the case for 0.95
the first layer depends on distance and EM
you cant tune EM on a single layer
thats not possible

The distance is just right, if it is lower, it will not squeeze out enough
you dontz know if the distance is right
you cant tune EM on the first layeer
thats not possible
again, first tune EM, then first layer
follow this guide

Will the EM value continue to increase?
follow the guide

I tried 1 0.95 0.9 0.85 0.8 0.75, as the value gets lower and lower, the spacing will become larger
follow the guide
DONT DO IT ON THE FIRST LAYER
this is impossible
follow the guide please

ok, I will look at the guide and try to adjust it after get off work to see if it can improve
Both the calibrate extruder and the pressure propulsion have been tested and have met the standard
EM needs to be first, PA later, if your EM isnt tuned, the PA value will be wrong
and the extruder doesnt need to be calibrated

Oh, I have read this guide, other layers are performing well, only the first layer will have this kind of situation where the line spacing seems to be large.
