[Consistent Inconsistent/Uneven Layers After Upgrading Ender 3]

@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.

@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.
