try to use a Input instead of OEMTrig.

what Controller are you using?

Hello,

i think the Problem is in this Sub:


'Sequence to determine the least travel to move for TC, CW or CCW
'atp = Actual tool position, rtp = Requested tool positon
Sub LeastTravel()
   NTool = 16 ' Number of tools changer holds
   CWPos = GetSelectedTool() - GetCurrentTool() ' Assume a CW move
   If CWPos < 0 Then ' CWPos < 0 ==> rtp < atp
      CWPos = CWPos + NTools
   End If
   CCWPos = NTools - CWPos
   If CWPos < CCWPos Then
      call CW()
   Else
      call CCW()
   End If
End Sub

should be IMHO


'Sequence to determine the least travel to move for TC, CW or CCW
'atp = Actual tool position, rtp = Requested tool positon
Sub LeastTravel()
   NTools = 16 ' Number of tools changer holds
   CWPos = GetSelectedTool() - GetCurrentTool() ' Assume a CW move
   If CWPos < 0 Then ' CWPos < 0 ==> rtp < atp
      CWPos = CWPos + NTools
   End If
   CCWPos = NTools - CWPos
   If CWPos < CCWPos Then
      call CW()
   Else
      call CCW()
   End If
End Sub

G-Code, CAD, and CAM discussions / Re: Mach3 stops at the macro. Why?

HI,
there is a fault in your M20 macro at the SUB StopRewindSleep

Code: [Select]

'-------------------------------------------
Sub StopRewindSleep ()
   DoOEMButton(1003)
   DoOEMButton()
   Sleep(150)
End Sub


the DoOEMButton(), because the Argument is not optional.

because of the Name of the SUB i think it should be:

DoOEMButton(1002)

But do you measure tool lengths "on" the machine i.e. tell you want to load tool 10 into the carousel so you fit tool 10, it goes and measures the offset, stores it and then unloads the spindle into the carousel??

that's what i am doing on my older machine, but on the Tongil, i measure them offline with
the function, that the length is written direct into tooltable.

no the M6 is not defect.
it seams to be handled different between G-Code call, and macro call.
i guess it is affected, because it is a "System" macro like M3 M4...

Hi Dave,

during the retrofit of my TongIl TNV40 (witch is still not finished), i came also to the
probing  / toollength question.

i am trying to explain, how i want to "handle" this, just to give you (maybe) some ideas.

some basic's of the TongIl
-BT40 spindle toolclamp spring loaded and pneumitc tool release
-16 place umbrella toolchanger

i got to the question 16 places, but i have more than 16 Tools?
so i created Screen and script functionality to use the full range of Mach Tooltable,
according to the 16 place TC. means i created a Little database (well it is a Textfile) to
create a relationship between Tools (Mach tooltable) and TC places.
so now i can "book in" a tool to TC place and M6 handles to get the tool from the right
TC place. that gave me the "range" of the full Mach tooltable.

next question BT40 spindle, but i have a lot of SK40 Tools?  
they are principly the same, exept the pick and place height of Z-axis, and a different look pin (lenght).
look pin's are avaliable, so no Problem, but the different pick/place , ok added this Information also
to my "extrenal" datebase some Scripting, done.


next question was how to handle the tool lenght?  
out of your thread i "grabbed" the idea of the tool lenght setter.
so some material laying around ,some Screen work, some VB Scripting later
the tool setter was finished , toollenght is stored automatcly in the Mach tooltable.

next question surface probing?  
i digged out a 3d touch probe (chineese) witch i buyed years ago, did some testing,
tolerance 0.01-0.02mm good enough for what i do.
again some Screen work, some Scripting and it does what i Need.

after all this i recogized, i don't Need a touchplate (or sensor, witch i use on an older machine) to
get the tool lenght.

i write this only to give you some more idea's,
if you want to take some, the coding is no Problem.

ok,
i have tested this on my machine, where i can do a real toolchange.

and you are absolute right, the macro is not waiting for the M6 to be finished.

so i made a Little Workaround.

code for the M6 call:

Code: [Select]

SetUserLed(1400,0)

Code "M6 T8"

While GetUserLed(1400) = 0
Sleep(50)
Wend

and then the last line in M6 is:

Code: [Select]

SetUserLed(1400,1)

so the calling macro has to wait until M6 set's UserLed(1400).

you have also to find an other mechanism to know that the run of M6 was faulty,
to cancel the main macro as well.

the trick with the UserLed is "dirty".
i would get the M6 code in a function inside your main macro, and create a returnvalue to
have the control in main macro by a fault.

i have also no idea about the Quality of These part's.

i buyed mine, figured out the tolerance was below 0,05mm,
and that was good enough for this case.

only covered the code into a

Sub Main()

End Sub

and replaced the MachMSG to MSGBox, they seemed not to work on my System.
