Hi,

post your vbscript an we will see, but remember
the probing is only measuring the length of the
tool, nothing else.

Hi,

a simple example for metric would be:

Sub Main

cutheight = 20
cutpos = 0
ZProbePos = 0

    Code "G31 Z-200 F150" 'do the probing
    While IsMoving() 'wait for finish
    Wend           
   
    'get the position where we hit the probe
    ZProbePos = GetVar(2002)   
    cutpos = ZProbePos - cutheight

    'go to cutting heigt
    code "G1 Z" + cutpos + "F100"

    'set new z-Pos
    SetDRO(2,cutheight)

End Sub

not tested, just written down.

what exactly did not work ?

did you do a ref all after the probe ?

only half of it worked and then it says "Error Line:17_mismatch" and yes i did click on ref all after the probe the same error appeared .... does this script that you sent me works with every time i start a program on mach3? like does it move every time or just once only when i click on ref all??

ok, here the corrected version:

Sub Main

cutheight = 20
cutpos = 0
ZProbePos = 0

    Code "G31 Z-200 F150" 'do the probing
    While IsMoving() 'wait for finish
    Wend           
   
    'get the position where we hit the probe
    ZProbePos = GetVar(2002)   
    cutpos = ZProbePos - cutheight

    'go to cutting heigt
    code "G1 Z" + CStr(cutpos) + "F100"

    'set new z-Pos
    SetDRO(2,cutheight)

End Sub


but the logic  sequence would be to do a ref all first,
and the run the script, because the ref Z will "destroy"
your probe height.
