bottom surface

[dwhite1957 0]

The bottom of the pieces I am printing are unacceptable. I need a finish on the bottom  (pictured on the left) that is the same as the top surface (pictured on the right). I know the grooves have support structures in them, I can clean them up. 

 

I am using a creality cr-10 v3, the  4.82 slicer, printing with wood PLA filament, nozzle temp at 200, bed temp at 60, using a brim for adhesion. My bed is a glass bed.

 

I am new to 3D printing so please speak in terms of someone that has more years behind them than in front of them. 

 

Thank You

David White

It looks like not enough squish on the first layer.  You can try adjusting the "Initial Layer Flow" to 120% to compensate but it's really a "leveling" thing.  The nozzle is too far from the bed to get a good squish and weld the extrusions together and that is why you are seeing all the gaps - the extrusions are remaining round instead of being smooshed together.
