Try this way

LoadMatX = GetUserDRO(1017)' read the stored values
LoadMatY = GetUserDRO(1018)
LoadMatZ = GetUserDRO(1019)


DoButton(24)
RefCombination (1 + 2)
While IsMoving()
Sleep(10)
Wend
Code "G92 X0.00 Y0.00 Z0.00"
While Ismoving()
Sleep(10)
Wend
Sleep (2000)
Code ("G53  X" & LoadMatX & " Y" & LoadMatY & " F1500")
While IsMoving()
Sleep(10)
Wend
Code ("G53 Z" & LoadMatZ & " F600")'

Metcutr it will depend on your depth of machining experience as to IF the Mach3 will do the job. There are things that MAch3 does not do well as compared to fanuc based machines.

Nested subs have problems
Toolcomp and subs have problems
There is NO conditional code in mach3
Good macro control is borderline
Some things are strange (Pause/stop)compared to the fanuc type controls.
restarts can be tricky

Now if you are using CAM and not doing alot of special coding then code wise you should be ok.

Converting from your old analog drives you will have to run one of the outside controllers to be able to interface the analog drives they are NOT cheap and can add other things that may not work as expected. This is not allways an easything to do IF you are not electronic savy so to speak.

Not really knocking mach3 as it is a very good hobby controller BUT in the comercial world it HAS its limitations.

NOW you have had the $20 lecture if you are adventurous and have the time and $$$$  go for it.

OK with some testing It is NOT the Leadin to arc bug IT was a case where the intial leadin move was not long enough before the first arc and it force the TC to use part of the arc as well. This can cause MAch3 to do some strange math.

Try THis I just extended the initial leadins a touch .

YEP that is the leadin arc to an arc problem When using ToolComp in some versions. I am using .043.022 and it does it here.

What version Mach3 are you running?

Just for the record they STILL make "new" ISA motherboards(;-).

To do the analog conversion by the time you are done converting everything you will have a pretty good chunk of change in the conversion. AND a lot of time. AND it may or may not do everything it did before you converted it.

IF all it took to keep the machine running was a new MB and hardrives THAT is cheap.

IF it makes you happy that is all that matters(;-)

You may want to look at something like this as a comparison. It starts by measuing the master then you can set as many tool#s as you like or cancel to end.

Sub Main()   
 'Macro for tool setting
code " G28 Z0.000"
code " G28 X0.000 Y0.000"
While Ismoving()
Sleep(10)
Wend

'Set Master Tool Routine
MsgBox(" Place the Master tool into the spindle")
Tnum = Question ("Tool Number?")
Ret = MachMsg ("Are you ready to run the MasterTool setting function?", "MasterTool", 1)
If Ret=2 Then End
code "G31 z-10 f20."
While IsMoving()
Sleep(10)
Wend
PRP= (GetVar(2002)+.2)
code "G0 z" & PRP
code "G31 z-10. f3."
While IsMoving()
Sleep(10)
Wend
Code"G92 Z0.000"
Tlo=GetDro(2)
Code" G28 Z0.000"
SetToolParam(Tnum,2,Tlo)

N1:
' SetNext Tool Routine
Ret = MachMsg ("Are you ready to run the Next Tool Setting function?", "MasterTool", 1)
If Ret=2 Then End
Tnum = Question ("Tool Number?")
MsgBox(" Place the NEXT tool into the spindle THEN press OK Routine Will Start.")


code "G31 z-10 f20."
While IsMoving()
Sleep(10)
Wend
PRP= (GetVar(2002)+.2)
code "G0 z" & PRP
code "G31 z-10 f3."
While IsMoving()
Sleep(10)
Wend
Tlo=GetDro(2)
Code" G28 Z0.000"
SetToolParam(Tnum,2,Tlo)
While Ismoving()
Sleep(10)
Wend
GoTo N1

End Sub

You are correct the Get Var() is the correct call. I have been flipping back and forth in the Fanuc world a lot lately and they call them parameters(;-)

I am not sure WHY you keep invoking the G43 H# it should have nothing to do with what you are trying to do.

Probe the master tool, set the Z to zero and the TOOL offset to Zero

Probe the next tool Apply the Z value as that tool offset (it will show the difference between the master and the set tool Remember the master is Zero)
PRobe the next tool and apply the Zvalue as that tool offset

etc
etc
Untill  you run out of tools to set.

That is basically all there is to it.

Just a thought, (;-)TP
