Hole size compensation
I have a lot of CAD designed items for printing. These interoperate with non-printed mechanical parts, so I need to keep the CAD designs true, rather than compensating in the CAD design for holes printing smaller than per-design.
I've tried hole compensation in other slicers and while I am able to dial in the size I need, doing so always introduces other artifacts that are problematic.
I tried the XY size compensation in Prusa Slicer but this seems to impact everything not just holes. There are other things to tweak in the print settings but I'm starting to suspect I'll pay a price for anything, and that this is just not the best layer in the workflow for hole size compensation.
Wondering if any of you have worked out a clever trick for this, like maybe some automated pre-processing step after CAD but before slicing.
I dont want to manually edit a second set of design docs every time a make a change, I would. bleed out on that.
Thanks.
RE: Hole size compensation
Just make the hole settings parametric and set a conditional for additive/subtractive implementation; then calibrate for the working values.
Cheerio,

There's no simply trick, just try and error. Too much dependent on geometry, printer tolerances, and material properties.

RE: Hole size compensation
I had to dig into that a little bit since some of it was unfamiliar, but it was exactly the sort of thing I've been looking for. Thanks for the help, I really appreciate it.

The problem with this is that if you're designing a model to be uploaded to printables or thingiverse, you want your model to be dimensionally accurate, and not modeled for your specific printer setup. This needs to be an adjustment a user makes.
Or take the situation where you have two different printers which have different tolerances. Now you have to adjust the model to each printer. Not a good solution.

It's no longer worth uploading, the effort required properly to test and document a part is wasted.
But if he calibrations are parametric the user can recalibrate...

Again, parametric recalibration addresses the issue.
Cheerio,
