Spiral toolpath: Can't get rid of linking/retract moves?

[FrodoLoggins]

The fillet looks good but the flat section has a lot of retracts, leaves a little extra stock, and treats sections of cutting moves as linking moves:

Hi @FrodoLoggins ,

Thanks for feedback. Cutting paths are trimmed against bottom plane as they might be in tolrance from surface. Just use small negative offset to avoid trimming.
