Awesome project! I wish I had a machine like this

Impressive work so far!

Pallet load/unload. (this is all done in ladder)

I don't know if you have this, but on my old K&T 600 the pallets could be indentified by a series of screws in the side (kind of a binary code) and the machine would run the program associated with the ID number of the pallet.

Nope - I think the 600 was a gen or 2 newer. The only thing that is barcoded are the tools. It did have a tape drive for each pallet iirc.

Have the B axis hacked together. This is more of an indexer as it has a
72 tooth curvic coupling that the table sit on which gives us 5 degree
indexes.

So far so good. The locking rotaries that one of the developers added works very well.
I think I need to add a little delay after the unlock switch is tripped
before the motion starts.

The first movement in both videos are the home to index only. The table
lifts off of its curvic coupling rotates until it finds the index -
rotates back to a point that will place it so the coupling will line up
- then re-clamps the table.

Getting there!!

Did a little milling. Needed to cut a hex in the center of a timing pully for the encoder that will be on the spindle for rigid tapping (and maybe closed loop speed control)

this is the hex on the end of the spindle that it will be mounted to.

This is where we are trying to shoe horn the encoder in. (the smallest hex is where the timing belt is going.)

fully auto! (pallet tranfer) could use a little optimization - but I am
happy with it. (because it works )

[nomedia="http://www.youtube.com/watch?v=CYA5uEwLSTA"]YouTube - full auto pallet transfer - opposite from previous video [/nomedia]

right now I have a few buttons on a pyvcp pannel to do activate the
cycles (offload pallet, swap pallets, Load pallet) and plan to activate
it with M1XX codes in the future.
