Tangential blade

[modflod]

I'm considering an attachment to my machine to hold a knife or pizza wheel cutter. Is there a feature in Cambam that can send g-code to an axis that would keep the blade tangent to the cut?

Short answer, No.

There is plugin for drag knife only.

I know of no specific feature in CB to do that, but I think a post-build processor could derive that information and calculate it, if you chose arc-segments small enough.

If you want to use tangential cutter the spindle needs to indexable. Or build attachment that hold stepper motor and drive it as A drive..

Bubba, yes.

But you still need the code to drive it.  Do you have a post-processor that will do that?

No, but maybe your driving software can do it ; it is the case with Mach3 and UCCNC. In this case no needs to create a specific GCode.

Thanks for the input. Too bad I'm not using Mach3 on this machine, the software doesnt have that function.

Ah ! .. no luck 

What is your driving software ?

Small business in Florida, he builds the CNCs and did all the programming, custom running software.  Fantastic support, i.e. I asked him and he said he'd program that feature in for me

It look like linux based control software.
