for the moment i am little bit confused about the ligic of input1 for doing one step of ATC

in the original macro:

--> UNTIL IN4 OR STOPSW
--> REPEAT
--> UNTIL !IN4 OR STOPSW
--> REPEAT
--> UNTIL IN4 OR STOPSW
--> REPEAT
--> UNTIL !IN4 OR STOPSW

it looks like it is ON at the start

then OFF ON OFF ON

to do one step at ATC

please describe the pattern of input1 to do one step.

Thomas

Hello, that correct it will start ON
then OFF ON OFF ON (ending in ON)
this would equal 1 tool position so if i was at tool 1 and ran that id end up at tool 2 if i was at 1 and ran it in ccw it would be tool 8.

ok then something like this should be closer:
Code:
Sub Main()
'Global variables declaration

Dim CCWPos as Integer
Dim CWPos as Integer


NewTool = GetSelectedTool()
OldTool = GetCurrentTool()

While NewTool > 8
NewTool = Question ("Enter New Tool Number up to " & MaxToolNum)
Wend

If NewTool = OldTool Then'Compare between actual tool and requested tool
   Else
   End If
If NewTool > 8 Then'requested tool higher then tool numbers
   Else
   End If
If NewTool < 1 Then'tool number to low
   Else
   End If

code("m05")
   Call ZatcPosition
   Call AtcIn'Activate air cylinder valve to put old tool back to carrousel
   Call Unclamp'Spindle: Tool Unclamp
   Call AtcDown'lowers atc
   Call LeastTravel'determine the least travel to move and Turns CW or CCW
   Call AtcUp'raises atc
   Call Clamp'Spindle: Tool Clamp
   Call AtcOut'retracts atc
   Call SetUserDRO (1200,NewTool)'Store new tool as actual tool value
SetCurrentTool( NewTool )

End Sub

Function ZatcPosition()'Move to Z tool position and wait until position reached
   code("G53")'Move in Absolute Machine coordinates
   code("G00 Z-1") 'Z value as to be checked for exact match with carrousel height

   Wend
End Function

Function AtcIn()'Put old tool back to carrousel
      ActivateSignal(OUTPUT4)'Move carrousel air cylinder to the tool change position adjust output# to match atc slide
      code("g04 p01")
End Function

Function Unclamp()'Spindle: Tool Unclamp
       ActivateSignal(OUTPUT6)'Release the tool, adjust output number for drawbar output
code("g04 p01")'pause
End Function

   ActivateSignal(OUTPUT5)'solonoid to lower atc
   code("G04 p01")'pause
End Function

'Sequence to determine the least travel to move for TC, CW or CCW
Function LeastTravel()
   NewTool = GetSelectedTool()
   OldTool = GetCurrentTool()
 
    NTool = 8 ' 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 Function

Hello, i tried that and its much better. i will tinker with it a bit and try to see what the issues, it seems to work fine if i change 1 tool number at a time (ex. t7 to t8) if i go multiple (ex. t1 to t4) it acts up. it seems like it over shoots the sensor some times like the response time is to slow so instead of ending with input1 active it will over shoot and end in a non active state.

Thanks for all your help so far.
