General Mach Discussion / Re: radius

« on: January 03, 2007, 04:02:08 PM »

You can't do it like that, you can only do it in 2 moves, like this :-

G00 X0 Z0
G03 X.875 Z-.4375 R.4375 F1.
G03 X.250 Z-.8568 R.4375
G01 Z-1.
G00 X1.
M30

The problem you will have is getting the tool down the back of the ball.

You can not have a radius bigger than half the diameter of the part with a Z move that is past the center of the rad.

if you want a .250 dia ball end on your bar you would enter :-

g20 g40 g90
g00 x0 z0
g03 x.250 z-.125 r.125
g01 z-.500
x1.
m30

Has the last line of the macro got a carriage return on it?

Will you post the macro and let me have a try here.

Have you got the macro saved in the correct directory.

If you are using a profile it must be in the profile's macro directory.  If not then in Mach3mill or Mach3turn's directory.

Is this an M code macro?

Should work like this

Graham.


(#1001 = X Axis)
(#1002 = A Axis)
(#1003 = A Axis Increment)

#1001=0
#1002=22.5
#1003=22.5
M98 P1002 L9
M30

O1002
M98 P1001 L8
#1001=[#1001+.333]
#1003=[#1003+20]
M99

O1001
g0 x#1001 A#1003
G73 z-.04 r.0 q.02 f3
#1002=[#1003+45]
M99

The other way is to program all your Z axis moves from the top of the table e.g. all Z moves are plus.

Hi Terry,

thats not easy to do as everybody's setup is different.

Try setting the velocity at 500, acceleration at 100 for a start.

Then run the roadrunner and see how it looks and sounds,  at these settings you should hear the motors ramp up and down quite a bit.

Keep increasing the velocity by about 50 at a time until it starts to stall, then back it off by 50.

Then try dropping the acceleration 5 at a time until you get stalling, then up it again.

I am afraid its all suck it and see with motor tuning.

Hi Terry,

standard V threads will work, they are not the most accurate but they should repeat.

The type of thread used will not cause you to loose steps, but the backlash may be a problem.

Have you checked the backlash?

If you slow down the velocity and increased the acceleration time do you still have the same problem?

Graham.
