I have rigid tapping on my super mini mill and it's worked flawlessly.

The super mini mill has an umbrella style tool holder.

Recently I purchased a Haas DM-2 that has the side mount tool holder.

The tool changer has worked with no issues.

Today I did my first tapping operation on the DM-2 ( it also has the rigid tapping feature )

The tapping portion worked, but when it went to change to the next tool, the tool holder fell on the table, and the next tool didn't load properly because I'm guessing the notches were not lined up correctly.

I am using Fusion for creating my code, and I used the same post processor as I have used for the super mini mill.

I'm wondering if I don't need a spindle orient line at the end of the tapping operation to get the cogs in the spindle lined up before the tool change?

Or is there a parameter setting that needs to be changed to make this happen after all tapping operations?

Like I said before, the tool changer has been working perfectly, so I think it has something to do with the tapping operation that left the cogs not lined up correctly.

Any thoughts or suggestions would be appreciated...

Here is the code from the tapping operation.
