MK3S+: Holes are printed proportionally too large
Hello everyone,
I recently exchanged my MK3S+ for another one. Since then, I have noticed a phenomenon for which I cannot find a real solution.
The printer has a Revo hot end and is fully calibrated. I am working with the Orca slicer.
The outer dimensions in the X-Y plane generally look acceptable, normally <0.15 mm. However, it generally prints holes in XY that are so large that the functionality of the component may be impaired under certain circumstances. Of course, I could work with X-Y hole compensation here, but the holes deviate from their target diameter by a certain percentage. A 30 mm hole has a diameter of 30.5 mm, a 20 mm hole is 20.25 mm, and so on. Each hole is approximately 1.5% larger than the target diameter, which is why a fixed compensation value cannot solve my problem.
Does anyone have any idea what the problem could be?
Thanks!

Shrinkage compensation in your filament settings. As part of my calibration settings, after I do the extrusion calibration, I print a test cube and calibrate the shrinkage for every filament I use. You have to be in Normal or Advanced mode in Prusa Slicer to adjust this setting. Orca should have something similar. I do this procedure for every roll of filament now. I have found the settings for one roll to the next can make a small change.
Under Filament > Advanced > Shrinkage compensation
From a cube I just happen to have sitting on my desk. 30mm cube. Measure 29.95 for X 29.93 for Y 30.09 for Z.
