I am getting a snake skin / vibration like pattern across all prints on one of my P1Ps across many different gcodes. The same prints work on many different printers in my farm with no issues. I only print with PLA and use generic filament settings.
I have cleaned carbon rods and “lubed” with alcohol many times (not a stranger to this with multiple printers), cleaned and lubed screws and steel rods. Checked all pulleys and gears for anything abnormal. I actually ended up replacing the carbon rod assembly and nothing changed with the prints. Something seems loose but I can’t seem to pin point it. Replaced a couple complete nozzle assemblies. Replaced extruder gear.
If anyone has ideas I’d greatly appreciate it!!

that looks crazy. can you wiggle around the print head?
have you tried to run a complete printer calibration in the settings?
dont know if this is it either, but i was reading maybe double check the jerk/acceleration settings and Pressure advance.
Good luck!

Have you printed a different model? That model appears to have a textured surface modeled in (or at least looks like it).
Maybe make a basic calibration cube or a benchy.

The print head doesn’t seem to have excessive wiggle. To replace the carbon rods I had to completely swap the print head. I have also been through a couple complete nozzle assemblies and re tightened them. I have done a calibration before and after the carbon rod replacement.
This same pattern shows up across many different models. All models that print without the pattern on other printers print with the pattern on this printer with the exact same gcode file. It shows up on a benchy prints.

Check for play in the Z axis?
When was the last time you totally cleaned the Z axis rods and lubed them?
After your question, I went ahead and completely cleaned and lubed the Z axis rods and screws to look good as new. I checked tightness of any screws related to the Z axis and re-tensioned the Z axis belt. Still getting the pattern 
. A second printer in my farm is starting to show signs of the pattern. Appreciate everyones input, pulling my hair out over this one…
you never said if you calibrated the printer again.
in the printer settings, just go in for a full calibration.
Is it only that file? or all prints?
Are you re-using the same gcode? or slicing every time before you send to print?
Thats the only way i could see this transferring to another printer. unless its a file/slicer problem
try orca slicer? if you use orca, try bambu Studio
First you should turn off the ‘enhance snake skin effect’ box 
Then you will find that checking your calibration will show that you need to make some adjustments.
What you see is usually a sign of under-extrusion when printing with PETG and such.
But even with PLA and badly calibrated filament will give you these results.
If you use old 3MF files then try again by just importing the geometry so the current slicer version can provide a gcode that matches your firmware
