Is there any way to chamfer curved surface?

[s.shokalskiy]

I'm trying to chamfer this surface (made with emboss) to make my model 3d-printabe. Chamfer works in a small range, but when I increase distance chamfer fails. Is there any way to make a larger chamfer than one on the picture?

normally, yes, you can chamfer these edges.  But, I can tell just from the image, there will be issues.  Lots of small, nearly tangent edges will make it difficult to succeed.

Ok, thaks. So how can I chamfer excactly surface from the picture? (which steps)

Here you are 😃 I've done chamfer where it should be on the maximum distance it was allowed. This chamfer should be on all the numbers and squares on this cylinder.

I traced over the curves in the numbers.  If you look at the sketch for those, there are very many, small segments, and those will drive the blend engine (fillet, chamfer) crazy.  It took me about 10 mins to do this - practical for 3 numbers, not so much if the string were any longer.
