General Mach Discussion / Re: edge finding/2.5D probing

« on: June 15, 2011, 06:45:30 PM »

I looked at that, thank you.

I downloaded Stirling's program, but i can't get it working. Probe comes down, moves forward to contact, retracts, moves forward to contact and then stops. I have adjusted speeds and acceleration up and down. I'm not sure what to try next. I think I'm almost there. Help.

EDIT: By Stirling. As I explained in our PM correspondence it clearly states in your controller manual that Ajax handles G31/probing differently from the standard Mach3 way and that's why my routines don't work FOR YOU. It's unlikely that ANY Mach probing routines will work with the Ajax controller UNLESS they're specifically written for it.

Any new stuff going on with edge probing?

I tried changing the G91's in the script to G90's, and now it works.
Thanks agin for everyones help.
My probe is alive!

It makes two short -Z moves, then rapids X about 2 inches, then continues at F4 in the same direction untill I touch the probe to stop it. Then repeats in -X, Y, and -Y. Then goes to center and displays diameter.
Here's the code:

  Rem VBScript To center probe outside diameter

If GetOemLed (825) <> 0 Then 'Check to see if the probe is already grounded or faulty

    Code "(Probe plate is grounded, check connection and try again)"

Else

    FeedCurrent = GetOemDRO(818) 'Get the current settings
    XCurrent = GetDro(0)
    YCurrent = GetDro(1)
    OutsideDiameter = GetUserDRO(1152)

    Code "G4 P1" 'Pause 1 second to give time to position probe plate
    While IsMoving ()
    Wend
    Call SetDro (0,0.000)
    While IsMoving ()
    Wend
    Call SetDro (1,0.000)
    Code "F4" 'slow feed rate to 4 ipm
    Code "G90 G0 X" &XNew + OutsideDiameter * .7
    Code "G91 G0 Z-.500"

Rem Probe Left

    XNew = Xcurrent - OutsideDiameter * .7
    Code "G31 X" &XNew
    While IsMoving() 'wait for the move to finish
    Wend
    XPos1 = GetVar(2000) 'get the probe touch location
    Code "G91 G0 Z.500"
    Code "G90 G0 X" &XCurrent 'rapid move back to start point
    Code "G91 G0 X" &XCurrent - OutsideDiameter * .7
    Code "G91 G0 Z-.500"

Rem Probe Right

    XNew = XCurrent + 3 'probe 3 inches to right
    Code "G31 X" &XNew
    While IsMoving()
    Wend
    XPos2 = GetVar(2000)
    Code "G91 G0 Z.500"
    XCenter = (XPos1 + XPos2) / 2 'center is midway between XPos1 and XPos2
    Code "G90 G0 X" &XCenter 'rapid move to the x center location
    While IsMoving ()
    Wend
    Call SetDro (0,0.000)
    Code "G4 P0.25"
    Code "G90 G0 Y" &YNew - OutsideDiameter * .7
    Code "G91 G0 Z-.500"

Rem Probe up

    YNew = YCurrent + 3
    Code "G31 Y" &YNew
    While IsMoving()
    Wend
    YPos1 = GetVar(2001)
    Code "G91 G0 Z.500"
    Code "G90 G0 Y" &YCurrent
    Code "G91 G0 Y" &YCurrent + OutsideDiameter * .7
    Code "G91 G0 Z-.500"

Rem Probe down

    YNew = YCurrent - 3
    Code "G31 Y" &YNew
    While IsMoving()
    Wend
    YPos2 = GetVar(2001)
    Code "G91 G0 Z.500"
    YCenter = (YPos1 + YPos2) / 2

Rem move To the center

    Code "G90 G0 Y" &YCenter
    While IsMoving ()
    Wend
    Call SetDro (1,0.000)
    While IsMoving ()
    Wend
    Call SetUserDro (1152,YPos2 - YPos1 - .200)

    Code "G4 P0.25"

    Code "F" &FeedCurrent 'restore starting feed rate

End If

Hi,
The saga continues. I installed the Hoss modified screen set, that has a probing screen. With some adjustments, I have edge finding, corner finding, and inside circle center finding working. When I try to outside circle center find, it does some crazy stuff. Has anybody got that to work well?

Yes.
I'll give it a try.

I think you need to return to what Terry said earlier;

"From the MDI screen type G31 X-2 F10 (followed by return) . The machine should start moving in the X- direction then trip the probe with your finger to see if it stops".

If the machine does not move, then we need to establish why.
Does the X Axis DRO indicate the move ?

Tweakie.

After fooling with it some more, I have it working. G31 X-2 F10, will now give me movement. I am so happy. Thank you all for giving me a fresh look at this. Information provided with the Ajax controller is confusing. Now I want to get a probe center finding program working.

I really do appriciate the help I'm getting, I feel I'm getting closer to solving this.

Here is the question and reply I just received from Ajax.
Captain Midnight,

Hi,
I am trying to install a Whitehorse probe. I am running Mach3 on the DC310B. The manual says to connect to H3 pin 6 and pin 5 on the MPU11. It says that should be input 481. My MPU11 I/O map doesn't have that input listed. It starts at 769 and goes to 786. To verify to connection by running CNC11, Pin 6 lights up LED 769. I tried setting  the Ajax Configuration Utility to Probe Input 769 and 481, but that will not light the Probe LED on the Mach3 diagnostic screen. My MPU11 I/O seemed to mapped differently than the manual's directions. I don't seem to have an Input 481 on my MPU11.
How can I resolve this?
Thank you
Captain Midnight

Captain Midnight
The Mach3 software has that input mapped differently than the CNC11 software. If you are trying to verify the operation in CNC11, when you press ALT+I, you will need to press F12 until you see inputs 769 thru 771. You could also use ModBus to look at input 481 in the Mach3 software to verify it is working. This is explained in the manual. Thanks.

It does'nt move.
