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.
