Are there standard test print STL's beyond the ratrig commissioning first layer test print?

I found some of course on thingiverse, but I'd like to use a standard set if they exist, vs just somebody's creation on thingverse.

There are several in Orca slicer under "Calibration"

Could also look up the "Cali-flower"

i highly recommend printing the calilantern while at it. Itll tell you skews etc as well

Thanks for those recommendations but I'm realizing now I still have more basic issues before I print those. I did a PA tower and set the PA to .05 in PrusaSlicer. But I'm noticing my first layer test print doesn't look all that good. I'm sure this has been seen a lot of times, but I don't know what's going on. Is this a PA issue the way the surface varies from the outer part to the inner part? I did the same print right at the front of the test bed and got the same result. I have done all the beacon calibration, z tilt, etc. I'll post more info if needed.

It looks to close or is overextruded. Did you baby step the first layer and save the offset or if it is beacon save_z_offset? From there you need to do a flow rate test and adjust the flow and then you should readjust your first layer and double check flow rate. The two of them are somewhat tied together for the first layer.

I haven't done any of that. I assume baby stepping means raise and lower the nozzle while printing. I'll try that and read about the flow rate too.

those are two steps that are required as you are commisinging your printer. If you want more background I like the tuning guide at ellis3dp https://ellis3dp.com/Print-Tuning-Guide/articles/first_layer_squish.html You dont need to worry about the extruder calibration if you are picking a standard extruder out of RatOS. Start at the build surface preperation and then go into the first layer squish and then pressure advance and then extrusion multiplier. If you want to find tune it better once you have your extrusion multiplier set go back to first layer squish and redo that, then PA and then EM again.

I did everything you suggested and gained some improvements, but adding "[gcode_macro RatOS] variable_beacon_scan_compensation_enable: True" to printer.cfg improved my prints even more. Because I had also been trying about everything I read all over the internet in the last few weeks for slicer settings, I wanted to clean them up and reset them to default, so I did. But now my "infill" doesn't quite connect to the perimeter. What self induced screw-up was this?

I remembered that several weeks ago I had followed the suggestion in the ratrig docs to set the first layer extrusion width to 130%, but that just got zeroed out when I set everything back to default. So just now I set back to 130% and it did fix the above problem pretty much, but it also over extrudes in the middle on the diagonal lines. Is there a better setting to use for this?

If only there was a setting called, "Print Settings>Advanced>Overlap>Infill/perimeters overlap:". Cuz if there was, I'd set it to like 40% and solve my problem.

There are some software issues with beacon and ratos that "should" be fixed but people are still testing. You can see in the beacon=contact and ratos-support channels for more information.

FYI: I use PrusaSlicer, but I discovered that OrcaSlicer has some good "built-in" test prints that I've used for testing. The Orca gcode causes RatOS to generate a couple of non critical errors in the console between each layer because I didn't take the time to edit/insert RatOS compatible gcode, but they generate good prints for testing.
