Mach3 Auto Tool Zero help

[JAZZCNC]

If my gauge height is 19.10mm how would the code change as i am unsure where it is entered.
And i will try this code on my machine as i am trying to get a zero z script to work

It will be a constant in the probe macro you are using. Post the macro and will take a look.

Hi dean
long time. i have a code here that is on machine but it gose down and touches then gose up about 50mm then when i remove probe and click goto zero it only moves about 25mm down

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 G31 Z-50 F255" '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, 19.10) ' change .060 to your plate thickness and then adjust for final accuracy
Sleep 200 'Pause for Dro to update.
Code "G1 Z25 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

Mark, can't see anything in the code that would make it do that. These are the lines that set the new Zero by entering the thickness of your probe plate into the Z DRO and then it retracts up to 25mm above new Zero so shouldn't go anywhere near 50mm.?

Do you have any tool height offset's set in the tool table.?

Call SetDro (2, 19.10) ' change .060 to your plate thickness and then adjust for final accuracy
Sleep 200 'Pause for Dro to update.
