Most issues im seeing is the over hangs in the ports and windows. I guess colder temps and or better cooling would help?
I measured and compared with the benchy guide and everything is within .09 of a mm.

Yes, apparently better cooling can help with overhangs. I'm not seeing any obvious ringing issues... did you find something specific and/or change a few settings?

The ringing is less visible but is still there. Id have to try the printer test again.
I did notice that the hatchbox filament prints super well, I also did change the extruder gripper for the aluminum one and calibrated the extruder using a mid point temperature (195c) of that filament. Maybe those helped a bit. Ill re print that mini test again tonight.

I did the mini test print last night. The writing on the front is much more defined and the stringing test is 90% better, the bridging is a tad better but over hangs are maybe worse\ same. Ringing is still present. Im gonna print out some belt tensioners and add some more support on the table, maybe hang a cinder block under it lol.. There is also is a mount for the extruder I might try.

Im also eying this cooler, really simple and fast to print.

Just finished installing the stepper motor dampers and Wow, they are at least 80% more quiet. lets see if the print quality is effected !

EDIT: Printed the same gcode benchy, looks just as good as the one without dampers. No quality suffrage with this printer and stepper dampers!

I saw your images in the other thread... where did you order the stepper drivers from? And yeah... it's one of those black magic things.... you wouldn't think that a "software" solution would be able to make a big difference on the sounds produced by a mechanical device.

I've got 4 hours left on a print that's taking one of my initial rolls of filament down to the nub.... I'm sure there's going to be enough to finish the job, but it's a bit nerve racking waiting for the print to finish.... :)

I got both the dampers and the tl smoothers off amazon. There is so much negative talk about the dampers but I printed 4 things since and havent seen anything off.. Ill for sure pick up the "silent" board too. If its quiet enough ill take off the dampers, if not, maybe a combo of the 2 would be ultra silent. But really, the loudest part of the printer is the heat stop fan and the filament stepper. Ill be changing the fan but I have to install the 24v to 12 v step down thingy (also purchased from amazon) for the noctua to work.. I also need to print the petsfang cooler as the 40x20mm fan wont fit the stock cooler. Plus the souped up blower fan I got wont fit either ;).

Have you tried the resume print function?

Only in passing.... I didn't know how it worked so I paused a print to try to clean up a minor issue but made the mistake of moving the Z axis to get at the print thinking that the "resume print" function would return the head to the appropriate starting location.... (that's not how it works.... :) ).

Let us know how you make out with the step-down kit (and provide a link if it works as advertised... :) ). Is it just for fans, or could a person tap off 12V for an LED strip?

Oh no! well you gotta learn some how eh.
Will do. I dont think the step down thing is designed for anything in particular, I assume it will supply 12v to what ever you plug into it.
What I would like to know is how much load those fan headers can handle.
