Detailed description of the problem
Printer model used P1S
Slicer settings used OrcaSlicer Max Flowrate calibration 5-35mm3/s
Any potentially useful information that is related to the problem What are the wavy artifacts on the side of the print, that is the only place this is happening, never seen this before. What is the recommended process of fixing this?
Artifacts like that are generally caused by wet filament or improper temperature.
I would first weigh, dry, then weigh you filament again to confirm the presence and then absence of moisture after drying. This will rule out moisture as a culprit. Please do not fall into the trap of “It was factory sealed”, we’ve seen enough factory sealed filaments and even PLA filaments have moisture issues.
The next issue could be related to improper temperature. Raise the temp 10-20C just to rule that out. Don’t go by what’s on the box.
I’m baffled by this surface. I’ve run the same OrcaSlicer test on many filaments and never saw this problem.
I don’t think wet filament is the problem since the other visible side looks OK and moisture usually causes defects more randomly.
I was tempted to blame excessive cooling by the auxiliary fan, but that does not explain the sharp boundary between the wavy surface and the curved corners.
It looks like the nozzle was unable to maintain travel in a straight line. Maybe turn off the printer and move the head by hand in that area, checking for excess friction?
The problem did not occur at low speeds and it gradually cleared up once “too high” speeds were reached… Belt movement and tension checked recently?
it stood for about 3 to 4 weeks without printing with the extruder in the parked position
I dried the PLA for 12 hours prior to this print because I was experiencing weird stringing with prints (not the thin strandy stringing, but more like extrusion not adhering to previous layers properly)
I have calibrated temp, pressure advance, and flow prior after seeing these artifacts in this calibration, but the issue still persists afterwards when trying this calibration again
I have not done a thorough maintenance (tensioning, cleaning, oiling, etc.) on this printer yet. sounds like this is a good time to see if that helps any
I moved the extruder around manually and did not feel any resistance or jerking in the area where the artifacts occur
the pressure advance tower calibration print did not have any artifacting on any of the sides and looked great (no stringing, separation like wet filament would cause)
I had to give this some thought and what follows is not necessarily a solution but more a series of possible diagnostic tests. I’ll skip over the diagnostics you already performed and cover the ones that weren’t mentioned.
Noteworthy background info
The 3MF file you uploaded is not usable for diagnostic purposes. The reason behind this is how Orca generates the diagnostic. When one loads your 3MF file, it does not carry over the settings you had. This what it looks like using the speed display.
Have you inspected the extruder for undue wear? Have you tried to replace it?
Have you disabled fans? I ask because it appears that the worst of the affect is on the far side of the model away from the fans. This could be cooling related issue.

Try out these two sample diagnostic GCODED files. They are 45degree offsets and have the embedded GCODE. You will not be able to modify them as they are static Gcode.
What follows are shortened versions of the Max Flow rate using a shortened model that should reproduce much quicker.
These are the settings used which are the same as you used:
Note that the color scheme selected needs to be “speed” so you can ensure that your GCODE is in place and that he speed varies throughout the model.
This forum does not support STEP file uploading but here is the modified file STEP file. Download this and change the extension from ".3MF" to ".STEP". SpeedTestStructureSquare.3mf (12.9 KB)
Navigate to the folder on your Orca Slicer where the STEP model is used in the Max Volume test. That folder name is %ProgramFiles%\OrcaSlicer\resources\calib\volumetric_speed Simply copy and paste this in the URL of your Windows Explorer folder navbar or simply hit “ – R” and paste the folder name.
Rename the current STEP file to STEP-BKUP and copy this step file into that folder. Then run your calibration from Orca. It will use the new file which is the example I showed above.
What Orca does is load that STEP file and then executes and internal subroutine to inject speed changes into the GCODE. The file name is hardcoded to "SpeedTestStructure.step"
– R” and paste the folder name.
