Angle probe

[kjetil]

Hi
I'm wondering how I can use angle probe in practice.
can this be used for example when I put a part on cnc and have to mill it, I then use angle probe to find the direction of the part. So when I have done that I can start the toolpatch and then the cnc keeps the direction?

Yea I wondered this as well. how can this be used in G code?

[kjetil]

Anyone?

If you guys are referring to G68, you simply probe a known face and the control rotates the work piece accordingly. Your posted gcode doesn't change as the control handles the rotation compensation.

Thanks
step by step then.
1: do an angle probe?

2: save angle.?

3: run your gcodes as usual?

4: angle compensation wil be used?

where can i get the G68 macro?

[cncdrive]

G68 is a g-code not a macro, it is built into the UCCNC and it does coordinate system rotation.
For the syntax and parameters of G68 please see the UCCNC users manual.
The G69 cancels the G68.

ok thanks
so then i shoud have it in my software,but how can i get the save settings button ?

in pracis how to do it,se i have probe some part and what is the next step then ?

The macro below reads the probed angle and rotates the work area at 0,0 to that angle.

Code: Select all

double angle = AS3.Getfielddouble(2715);                                        // Angle probe result from probe screen

exec.AddStatusmessage("Rotate: G68 A0 B0 R" + angle.ToString("F6"));

exec.Code("G68 A0 B0 R" + angle.ToString("F6"));                                // Rotate at 0,0 with angle degrees
while (exec.IsMoving());

thanks
i wil copy that and where to put it ,like a new macro i profiles??

how does it work ,wil it go automatic? or do i have to do something after a angle probe?

Yes, as I wrote, that is a macro. Save it to Mxxxx.txt into your macro directory. You can start it typing its name or if xxxx is 20000 to 21999 then you can create a button to call it.
