Minimum radius for tangential feedrate adaptation
This command completes the tangential feedrate adaptation programmed with G10/G11. The minimum radius is taken into account in circular blocks containing the identifier for feedrate adaptation. The feedrate only will be adapted, if the programmed circular contour radius is greater than or equal to the minimum radius.
#SET TANGFEED RMIN [ <expr> ] (modal)
<expr> Minimum contour radius Rmin at which the tangential feedrate is not applied.
- A new programmed minimum radius will be considered with the next relevant motion block.
- The declaration of the minimum radius is optional. The tangential feed rate adaptation also work if #SET TANGFEED RMIN is not programmed or the radius is set to zero.
