Hi Mike:
Actually, I just cut the nose cone in a block of spruce, it cut very well, and turned out perfect.
As to the blend radius. Think of it as the worst-case deviation from the path you have set. In reality, it follows a
"Ruile of 1/8th" . That is to say if two lines are joined to gether, the blend will be at most the setting in the dialog,
say..10mm as default, but will always be a maximum of either 1/8th the length of the shortest of the two lines, or the
set amount. SO two 100mm motions will have 10mm raidus by default, a 100mm line entering a 60mm line woudl have
60 * .125 = 7.5mm as its blend. In micro segment code, this means the blends will be very small to make it all very accurate,
if two lines are .1mm each, then the blend between them will be .0125mm radius.
In this way the accuracy increses as the line segment sizes shrinks. As blends shrink the max speed though them shrinks as well,
but the physical limits are generally high, so it isnt generally noticable. SO basically, a 10mm or in inch mode perhaps .5" would be good for all
program types as loong as a .5" radius is not too much for you. Set it as low as you like, its only a maximum.
I was very pleased at the running of the nose-cone, seemed to work well. Vary your jerk setting till you like the smoothness offered, and you should
be able to leave it there, though it can be handy to raise Jerk limits for very tight code to allow for faster motion overall.
