Bit Zero unable to probe

[KTKT (Milton Tunnell)]

Would anyone know why my bit zero keeps getting pushed out of the way when trying to probe?
I did take the collet out and put it back in, would that have anything to do with it?

Does it test as working before each use?

See:

Using/verifying the BitZero

Here is how I check out the functionality of the machine/BitZero: first check that you have sent the correct Z-axis configuration This can be easily done by jogging down to the wasteboard surface, setting zero, then using the Rapid Position command to lift 6mm above the current zero — measure how much the machine moved — if it’s wrong: open the Log Window go to the MDI (EDIT: Note that it will need to be enabled in options in current versions) and send $$ and check that the Z-axis steps/mm …

Thanks will try later today Worked just fine after I took the end mill out and put the pin in

Perhaps the endmill was dirty & not making electrical contact with the BitZero. When using end mills with the BitZero, they have to be clean of cutting residues to make proper contact. I usually use a bit of rubbing alcohol & rag or shop towel to clean off bits

And doing a quick touch test with the BitZero to the end mill before running a probe operation usually indicates whether or not the end mill needs cleaning.

Thanks I will remember that!
