adds always-on ramping into area cut

[dognotdog]

I added ramping into a cut, seems to produce the right gcode, but should of course be reviewed and the option from the GUI to do ramping is also currently ignored, but that shouldn't be very hard to add, except that I don't know the HeeksCNC internals very well.

The algorithm basically tries a 45deg or shallower ramp, but vertex-by-vertex, so sometimes the ramp can be very shallow if the vertices are far apart, but that shouldn't be a problem. The ramp ends at the curve's starting point, going backwards, so cutting direction is kept.

Had to do this as otherwise my mill isn't far from shaking itself apart when using crappy end mills for pocketing operations.

Cheers!

How do you use it if not with GUI ?

[dognotdog]

I've just hardcoded it to be always-on, as for the project I used it for that was a decent way to do things, but obviously thats a dirty hack :)

I have created a fork at https://github.com/bullestock/heekscnc/ which, among other fixes, includes the GUI to select Entry Move.

@bullestock I can integrate your changes if you make them available through small (ie. easy to read and review) Pull-Requests.

Thanks!

@neomilium Alas, I don't really have neither the time nor the inclination to do that - it was mostly a quick hack to get stuff working for my own use.
