Please add Legacy X-maker support

[WoodwardIII-HS]

I get it; it's an old machine that's not supported anymore, but please, the thing has been rock solid since day one, and I would love to see a new profile for it. It'd be very helpful to be able to use some of the more modern slicer features, like better tree supports. I know support for an old product is unlikely, but I figured I'd ask as, several years on, it's still my go-to.
