Post a picture with some dimensions of what you are trying to achieve.

make sure you have CV turned off in config.  CV and turning do not go well together. Set config to exact stop mode.

You can not use scaling to do this as scaling changes the centres/position of the letters as well as shrinking them.

Its just basic trig.  its all in degrees, you have to have a starting point somewhere in X and Z.

You can use the biggest dia or the length and an angle. the main point is to work out half the included angle and the length, then double it for diameter.

I do not use the wizards so I can not help you with them.

SIN of the angle.

e.g.

If taper is 20mm long @ 25 degrees included angle and the small dia is 20mm at Z zero then :-

X=20+((SIN(25/2)*20)*2)  i.e. 20+(((4.3287)*20)*2)
Z=-20

G00 X20 Z1.
G01 Z0 F.2
X28.657 Z-20.

To create a taper the X & Z must be commanded on the same line :-

e.g.

G00 X5. Z1. G97 S1000 M3
G01 Z0 F.1
X15. Z-5. (produce a taper @ 45 degrees)
X5. Z-10. (and back down the other size)
X20.
G00X50. Z50.
M30
