Hi Guys,

This grinding machine I've made is much the same as a lathe, X is Ø, and Z is length.

When I'm dressing a profile on a wheel, I need to enter twice the distance for X axis, because it's set to move 1/2 the distance per side, which work out to the correct in Ø.....huh

So if I'm dressing a profile that is 90° included and a small 1.00mm radius on the point, I need to enter the following:

G1 X10. Z-5.

G2 Z-1.41 R1.

X-10. Z-5.

I've noticed that the angles are perfect but the radius always seems to come out alot flatter that it should.

Do I need to compensate somehow for the way I've got it set on X axis (only actually moves in half of what you specify)?
