HA and HP don't need to be set, because the machine tool is set. HB= template-blade, HC=0, HD= head height. That's how templates don't mirror!

HB= knife edge, HC= plate thickness, HD= head height. This is the setup method after mirroring. G52 in the mirrored program can be converted into G5 1, which can be processed!

The top and bottom are inverted cones, and the blade is below.

Small on the top and big on the bottom, with the knife edge on it.

The z axis of the nose returns to zero 270 first!
