Auto Tool Zero button config problems in Mach3

So I have been trying to set up my Auto Tool Zero button in Mach3. I am using the standard code found online. When I push the button the Z axis travels down and touches the touch plate as it should but then retracts and continues to go up out of the limits of the machine. It does not stop at specified location. I am not good at gcode and was hoping someone can help me sort this out. I will attach the code I am using.

Thanks


CurrentFeed = GetOemDRO(818) 'Get the current feedrate to return to later
CurrentAbsInc = GetOemLED(48) 'Get the 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 P3" ' this delay gives me time to get from computer to hold probe in place
Code "G90 G31Z-1. F4" '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 exact 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, .123) ' change .060 to your plate thickness and then adjust for final accuracy
Sleep 200 'Pause for Dro to update.
Code "G1 Z.5 F50" 'put the Z retract height you want here, must be greater than the touch plate thickness
While IsMoving ()
Wend
Code "(Z axis is now zeroed)" 'puts this message in the status bar
Code "F" &CurrentFeed 'Returns to prior feed rate
Else
Code "(Z-Plate is grounded, check connection and try again)" 'this goes in the status bar if applicable
End If
If CurrentAbsInc = 0 Then 'if G91 was in effect before then return to it
Code "G91"
End If
If CurrentGMode = 0 Then 'if G0 was in effect before then return to it
Code "G0"
End If

Are you using the parallel port, or a motion controller?
If you have a Chinese motion controller, that code probably will not work.

Its a motion controller. Is there any code that will work for it? I am just looking at capturing the z axis zero. Like I said I'm not good with gcode

Thanks for your reply

Try getting rid of the GetVAR functions.

Replace ZProbePos = GetVar(2002)
with ZProbePos = GetOEMDRO(802)

and then see if it works.

That was the ticket. Works perfect now. Thanks for the help, I woulda never figured that out on my own

Glad to see that the Z zero is now working.
Will this code work on the Mach3 Version I recently downloaded, in the lower center of the screen there is a Zero utility, would this code work with it? Here’s a photo
Thanks
