Hi - stupid question here I’m sure, but I haven’t used anything other than spiral upcut bits. I’ve used straight bits with manual routing, but always come in from the side. I read that straight mills need to have a ramped lead-in instead of a straight plunge - but can they do helix entry?
Here’s an image of the default lead-in settings on F360:
Will a ramped helix entry be good for a straight 1F/2F bit?
