No. The .192 is the thickness of my plate.

Procedure:
1. Run Auto tool Zero
    Result...Z axis changed to 0000

2.  Hit Go to Zero
     Result...Z axis above material surface

3.  Hit Zero Z and Jog to material surface
    Result...1.525

4.  Hit Zero Z again and Jog to 1.192 (1 plus plate thickness)

5.   Hit Go To Zero
       Result...Z hits surface exactly!

 SO distance error is 1.525 less 1.192 = .333. I've run this series several times and come up with a different difference error each time. I'm thinking this eliminates machine error and suggests the script. Are there any hints as to the problem here?

Thanks.........dt

It works!....But when told to go to Z 0, it comes up short by ~1.5 inch off the material. Do you have any suggestions for that? I'm trying to parse the code but my brain came up short too.

Thanks.........dt

General Mach Discussion / Touch script not working, Help?
« on: March 31, 2022, 06:22:45 PM »
Hey guys. I've setup for Z zero touch plate. The Digitize DRO in Mach3 and the Data Monitor for the ESS are both indicating the "Touch".
But the script I found is not working. The Z axis starts it's move but has no reaction when the probe (Bit) hits the plate. Below is the script I found. Can someone point me to a better one or suggest a fix for the one I have?

CurrentFeed = GetOemDRO(818) 'Get the current feed rate to return to later
CurrentAbsinc = GetOemLED(48) 'Get current G90/G91 state
CurrentGmode = GetOemDRO(819) 'Get the current G0/G1 state

If GetOemLed (825)=0 Then 'Check to see if the probe is already grounded or faulty
DoOEMButton (1010) 'zero the Z axis so the probe move will start from here
Code "G4 P5" ' this delay gives me time to get from computer to hold probe in place
Code "G90 G31Z-2. F5" 'probing move, can set the feed rate here as well as how far to move
While IsMoving() 'wait while it happens
Wend
ZProbePos = GetVar(2002) 'get the axact point the probe was hit
Code "G0 Z" &ZProbePos 'go back to that point, always a very small amount of overrun
While IsMoving ()
Wend
Call SetDro (2, .192) 'set the Z axis DRO to whatever is set as plate thickness
sleep 200 'pause for Dro update.
Code "G1 Z1,F50" 'put the Z retract height you want here
Code "(Z axis is now zeroed)" 'puts this message in the status bar
Else
Code "(Z-Plate is grounded, check connection and try again)" 'this goes in the status bar if aplicable
Exit Sub
End If


Thanks.........dt

General Mach Discussion / surface probe setup, DRO intermittent
« on: March 25, 2022, 06:27:03 PM »
Hey guys. I've setup for surface probing. But the DRO is intermittent. When I hook up my meter to pin 15 on the bob,(cnc4pc) and the -V on the Z axis power supply I get consistent 1 ohm. But the DRO blinks couple of times and stops. A retouch does it again and stops.

I've attached the Script I used.

Yes I did. It didn't fix the problem and the motors would not run.

thanks......dt

Searching more on the internet I found two references to motor wiring. So I swapped the B+ and B- wires on X axis. Now it runs reverse but won't run the other direction, only in reverse. The motor sounds better though.
 Also found reference to connect DIR+ to 5v rather than DIR- to common? Now I'm really confused!

Oh, and thanks for your help TPS.......dt

No I'm not sure of the motor wiring. Do you have a suggestion for testing that?

Thanks.....dt

10
yes to wiring. I can see the change from 5v to 0v between DIR+ and DIR- when changing direction. Also, the Y axis did reverse, but only twice and then not again.

Thanks.....dt
