Old Stuff: Mach 3 Tool Number DRO
« on: November 22, 2019, 07:14:55 PM »
I recently set up one of my machines tool tables with tool lengths. 

When I execute a tool change it updates the tool length offset and Z DRO, but the tool number DRO still reads zero. 

My typical tool change command is T(x) M6 G43 H(x) where (x) is the tool number.

I can manually enter a tool number into the DRO and it applies the tool offset from the tool table if it is not already applied from a command like the one above.   

I run into this same issue on both the machine where I have implemented the tool table, and on the test installation on my design computer.  I spent over an hour looking for a solution by searching the forum, but was unable to find anything. 

Is there some setting in Mach configuration I am missing or do I need to add something to my tool change macros or both?

I found somebody's tool change macro that has what I need in it. 

'Tool Change Macro For Manual tool change 09/14 CNC4XR7
DoSpinStop()                     ' Make sure the spindle is OFF
Code"M09"                        ' Make sure the coolant is OFF
OldTool = GetOEMDRO (1224)  'Tool In spindle DRO You must add this to your settings screen
'x = GetToolChangeStart( 0 ) ' Get x tool change start position
'y = GetToolChangeStart( 1 ) ' Get y tool change start position
'z = GetToolChangeStart( 2 ) ' Get z tool change start position
tool = GetSelectedTool() ' tool to be changed to
NewTool = tool
If NewTool = OldTool Then 
        Exit Sub   
End If
Code "G53 G0 Z-1.0" ' Move z to tool change position in Machine cord.
While IsMoving ' wait for z to move
Call SetUserDRO (1224,NewTool)
SetCurrentTool( NewTool )  ' input new tool into tool in spindle dro

MyString = "Ok"   ' Perform some action
End If
'Show user the current tool description

His video is here: 

He has a link in the description to a drop box with a screen set and the macro at dropbox.  I edited the my screenset instead.
