General Mach Discussion / Re: Time to have new members have restricted posting rights

You have no idea just how many spammers we reject each day, in the last hour I have rejected 4. its an on going battle and they are getting better all the time.  As we have 24 hour moderation we get most of them before you see them, an odd one is going to get onto a board, all I can say is don't get upset, just click the report button and then every moderator gets to know about it and one of us will remove it.

In most CAM systems you can specify the segment length, this will then make the flats smaller or larger.

If you can just re-program VM to mill you a circle then it will output a G02/3 and the out side will then be smooth.

To mill a circle is very easy :-

(MILL 1.5 O/D BOSS WITH .375 DIA END MILL)

G20 G17 G80 G90
M6 T1
G43 H1
S1750 M3

G00 X.9375 Y0             (MOVE TO START)
Z0                               (MOVE TO TOP OF JOB)
G03 I-.9375 Z-.01 F5.    (MILL A CIRCLE AND MOVE DOWN .010")
G00 Z1.
M30

LM2197? I cant find any reference to that on the web. Is that a valid number?

No, Mach can do helix and spirals but only in long hand code, similar to the code you just posted that worked.

Have you set the steps per correctly in the motor tuning window?

What is creating the code for you?

if you run this code with a pencil in the chuck what size is the 25mm square it should be making

g21 g40 g00 g90
x0 y0 z25.
z0
g01 x25 f100.
y25.
x0
y0
g00 z25.

The problem is that you are using a spiral/helical pocketing routine in visual mill, use a normal area clearing routine and all will be well.

Mach3 dose not support spiral/helical milling in the same way

Hi Tony,

what are you using to control the spindle speed?

The large motor is 2.5A and the small one is 2A

Hi Terry,

Looks ok, is it working?
