Using an Ender 3 S1 Plus, with a sonic pad through Cura. All my prints have these weird bumps that I think are right after the initial layers are done.
It’s on every side, so it’s not like a shift on an axis, a bulge all around. Any ideas as it’s been baffling me
First thing I’d do is try a different slicer.
I think the flowrate is a little too high, what is your flowrate calibration looking like? I would also try a different slicer, Creality Print works fine for me, once the flowrate is right.
Do you mean pressure advance? I went through a pretty hefty calibration on that and its at .077
I have to say, the latest version of Creality Print finally got the print quality to where I can use it. Maybe I’ll have to go back from Orca. 
No I mean flowrate. It should be adjusted in the slicer program when you create the gcode, probably called flow ratio. On the sonic pad you can adjust it while it prints, on the adjust screen its the 3rd column along by 5/10/25% decrements. You can also adjust it in fluidd. You can have the perfect first layer but if the flowrate is too high it will start to bobble/ripple/tear.
It’s currently set at 95% for the profile. I just printed a new one with the latest .20mm CHEP profile and it looks a lot better, but still doing it at that one spot, wondering if something is wrong with my Z axis.
What is your temp setting for the build plate…?
That last print is looking better. The banding…is your X axis gantry screwed too tight to the Z screws? On the V3SE/KE there are 2 screws on each leadscrew that should not be wound up tight, loosening them by half a turn would allow the leadscrew nuts to float and compensate for any leadscrew issues.
Do you mean these two screws? Also thanks for all the help, kinda new to all of this so learning a lot!
60C for initial and print.
Yes those, Tighten them fully then back them off 1/2-1 turn, will allow the leadnut to take up Z wobble but still engaged enough to drive the X gantry.
Cool beans, they were tight as heck, so I loosened them a half turn and started my next print.
