What should be my first calibration steps on a new build?
-
Post your config.g just in case there is something odd there.
What slicer are you using ?
Did you configure your slicer for RRF (Rep Rap Firmware) ? If you have configured the slicer for the wrong firmware, all kinds of odd things start happening.
BTW, you shouldn't have seen a reasonable cube test print either. -
My nozzle is a .4, so again learning I'm thinking I could have a .4 wall. Maybe that's unrealistic. I have a duet3d board and use the configurator to put it together. I'm using cura 4.4.1
I can post my config if that helps.

Hi,
Consider the idealized images below.
The two circles on the left represent using line width that matches the nozzle size.
The two ovals on the right represent using a line width that is greater than the nozzle size.
As you can see you get much more contact between layers with a oval shape.
More contact will normally yield a stronger print.
This is misleading as you play down layer height. If you have a 0.4 mm nozzle and a 0.2 mm layer height you will never get the round shape on the left of your picture.
That's why I qualified it and did not specify a layer height of 0.2.
It was simply to point out the importance of good contact between layers, which under extrusion may prevent.

You can have a 0.4 mm wall although there is an argument to be made to set your wall line to 0.5 mm (I use 0.4mm line width if I use a 0.4 mm nozzle).
Yes, post your config.g
Have you measured the layer height of your first layer (the one you say is 0.8 mm wide?) -

You might get something out of this as a starter.
And then maybe this: https://forum.duet3d.com/post/130939

Height is .3

I can't see anything obviously wrong here that would account for your issues.
Are you saying that your first layer is 0.3mm high and 0.8 mm wide ?
What are your slicer settings for first line width and height ? -
That's correct
Layer H .2
Initial Layer H .3
Line Width .4
Wall line .8
Outer .8
Inner .8
Top / Bottom .4
Infill .4
Initiall layer line width 100%Wall line count 1
Top bottom thickness .8
Top layer 2
Bottom layers 2
Enable ironing checked
Infill Desity 40
Infil line distance 1mm
Temp 205
Plate 70
Ratraction Distance 2
Retraction speed 25mm/s
Print speed 40
Enable accelration control checked
Enable jerk control checked -
I am out of ideas, sorry ....
One thing though .... you say you measured line width at 0.8 mm ... was that measuring a SINGLE line or did you measure wall thickness (which is two lines and should be 0.8 mm)? -
Single line
