Radial Slot Subroutine

I had some time off from work, so I whipped this up. Use at your own risk. If you find issues, please let me know:

Known issues:
*Choosing an arc radius too small can cause weird paths.
*I'm not sure the transition from the side arcs to end end arcs is perfect yet.
*To flip the curve from convex to concave, switch P1 and P2 coordinates.

Have fun

...ved.

nice work -- thanks

There are also some arc gcode programs in the distribution (v2.5+ probably):

nc_files/ngcgui_lib/arc1.ngc and nc_files/ngcgui_lib/arc2.ngc

These use cutter radius compensation based on tool table tool diameter and provide additional methods for specifying an arc

Looks good, I will have to give it a try. Thanks for sharing.

I use something similar as far as calculations for multiple radial arcs and use G10 to set their locations.

G10 L2 P#<_pc:1> R#<start_angle> (rotate for start angle)
