In that case the fix should be in the just-released 2.9.5 release. (so you probably won't have to build from source again)

But skimming it doesn't look particularly promising.

I haven't made helical gears, but I am sure I could if I wanted to. It's just a matter of increasing the hob angle and adding in a proportion of the feed distance into the gear blank angular position.

Some links: My first YouTube video (filmed with a potato) where I explain the concept.



The current, much improved setup:



A screenshot of my (written just for me, so not very pretty) GUI. Of note is the top left section that calculates gear parameters based on entries in any gear system (mod, dp, cp). You will see that helix angle is included in the settings, but is currently not implemented.

Are you sure that EVAL[.....] is valid? Is that documented somewhere?

I don't recognise it as one of the documented unary functions, but can see examples of its use on the forums. I know that py and pyrun exist (I can see them in the source code, they may not be documented) but eval has me stumped.

I'm going to open it up under the Elastic License 2.0. The repo isn't public yet because the internal API is a mess and running it locally is not trivial. So for those that are wary of web services I'll also include a script to make running it locally easy.
