Hi Dave,

Do you get any message in the status window telling you the reason for the stop ?

Have you tried increasing the debounce interval in general config ? (just in case it's noise related).

General Mach Discussion / Re: Tool setting....?

« on: April 08, 2011, 08:54:06 AM »

As long as the approach is slow there is no problem with tool damage and copper clad board. The probing script stores the exact touch point whilst the axis drive is stopped, the overrun is only a thou, perhaps less and the surface of the copper clad takes this easily, Mach then returns the axis to the touch point plus whatever you have chosen for tool clearance so the accuracy is good. The probing script has to be right though, there is no room for error (spring loaded stuff) but, I haven't broken a 1mm endmill yet (but tomorrow is another day and who knows ?  )

Just two things spring to mind

1) check that the script box is completely empty before entering new script.
2) zero the z axis DRO before pressing the auto zero button.

( grasping a t straws here now   )

You could try replacing the auto zero button script with this very, cut down code and see if the problem still persists.

Message( "Auto Zeroing..." )
If IsSuchSignal (22) Then
code "G31 Z-3 F10"
While IsMoving()
Wend
Call SetDRO( 2, .180 )
code "G1 Z1"
End If

Is the touch plate itself operating correctly now ? - Digitize LED only illuminating when the plate touches the tool tip.

They are not stupid questions - don't forget I was in exactly the same position as you, a year ago perhaps (I couldn't get it to work first time either  )


I assume you are using an active BoB which is powered 5 Volts so take the +5V from there.
I would try a resistor about 10,000 ohms (10K) to see if that pulls the input up to 5Volts - if that doesn't do it then we will have to think again.

Do you have any details on your BoB make, model etc. ?

The probe input should be configured active low and the digitize LED should be off until the tool contacts the plate.
Could it be that your BoB is holding the input low and causing the digitize led to be on ?

Just tried the script on my machine and it works OK here.
The Z only moves up 1" after it has touched the plate. Silly question but have you got your Z axis reversed ? ( +Z should be upwards movement)

Thanks, but what I would like to see it is the script you are pasting into the auto zero button not the .xml
