Re: Ramp entry (helix) too steep
The term "IgnoreAbove" probably carries little meaning unless the user already understands the shorthand notation.
If I understand the logic, then "BeginAtStartDepth" might be a bit clearer.
Either way, a nice update.

Re: Ramp entry (helix) too steep
Good suggestion. Actually, I went even further and called them UseStartDepth and DressupStartDepth. PR is here:

Re: Ramp entry (helix) too steep
Hi roivai,
Th screenshot is taken at a Millface OP, but the behavior is the same at Pocket OP and Pocket 3D.
there is a new problem if using the ramp entry dressup: it only removes the ramp, not the whole material.

Re: Ramp entry (helix) too steep
I suppose you are using helix method? I think I have seen that at some point, then was not able to reproduce it and forgot the whole thing.. Basically what happens (I think) is that is does consider that round as the last round for some reason, maybe rounding error or something, so it does not add the final "flat" cutting loop. Can you send me that file?

Hi roivai,
yes it's the helix ramp, - and file is attached.

Re: Ramp entry (helix) too steep
Thanks for the file. The bug was even more obvious than I originally expected. When the dressup was searching for minimum Z on the path, it included the first edge from (0,0,0) to actual starting position. So it always found 0 as the minimum Z if the actual path did not go below zero. It seems that I've never tried this with a model where the bottom of the cut is above zero. Not very good testing coverage.
