@Greg, Thank you. I will try this out again on its mating part.

@Greg, Here is the STL file. Its my own design besides its only part of the entire assembly. Let me know your settings once you have fine tuned. 01-camera__Cover_GoPro.STL

@Greg, my solidworks export option is set as "Fine" Should I change to custom and reduce tolerances (See snap shot)? Where can I find the resolution settings? When I typed resolution in the search field there are Quality, Support, Mesh fixes, and experimental features comes up. If I am not mistaken you are referring to Mesh? Mine is set to .25 for resolutions, and Max deviation .025. Should I set Mesh resolution to 0.5? Global tolerance in Cartesian system meaning - Since its a XYZ gantry (Printer) and each axis has its tolerance, so if you take root sum square you end up with a number that the gantry can achieve theoretically. No need to discuss this any further 😉 Yes, I can live with 93.8mm compare to 93.75. Not sure if I understood thin wall analogy. I'll revisit that again later. Acceleration makes perfect sense should that be half of the speed as a starting point? Oh no its set as 500 mm/s^2. Should Jerk be set to less than 6mm/s? Thanks, again

@Greg, I have gone thru mechanical alignments and backlash issues using a dial indicator (old fashion way), but will recheck over extrusion again. What I cannot understand, is why only this particular part creates ridges and layer offsets compare to a simple extruded thin piece? Is it because its compounded curves that the printer cannot handle? I will also look into acceleration and dec profiles and jerk control. I am not familiar with these parameters. One last question I have, if my printer global tolerance in Cartesian system is 1mm, should my part thickness be more than 1mm so these layer steps are reduced? Hypothetically speaking

Has anyone figure out a solution to this problem? I am printing PLA on Ender 3 V2, with default settings. I have done extruder calibration, xyz cube, and bed level. A simple thin wall cube prints perfectly, but the minute I try to print large model I get really bad results as shown in picture.
