HAAS VF1 retrofit

Worst case i rework the shuttle and make the carousel drop instead of the Z axis.
Once i get movement then i can make parts

I know its been done befrore , just no one has posted how they did it.

Maybe good idea to start a thread just for this? "Carousel ATC with Z axis"

Well, time to go to work.

I thumbed thru the haas manual last nite. This uses a Geneva cam with a sensor of some sort to both count tools and indicate pocket center. In addition, it has two motors, one to move the carousel forward/back and one to rotate the carousel. I suspect both are three phase. The orient mechanism seems to work by letting the drive "coast" and firing the pin, the pin has a prox on it indicating the spindle is oriented. It appers the encoder was an option for rigid tapping. I by no means memorized the manual...
This machine is very very similar to the Leadwell RobH did in England. It might pay to ask to share. he did the tc and orient in ladder, I believe .

Shuttle and Carousel motor get their power from servo motor power supply 160vdc
which is supplied to the I/O board , controlled by forward and reverse relays for each.
I did notice resistors in the circuit , probably to limit current or provide a voltage drop.
the motors themselves say 130vdc.

The carousel is a gear motor/geneva
The shuttle is sort of like a arm type window lift mechanism in your car. Also has a slip clutch in the mix.

How about adding a second prox switch to the tool position pulse, that would give it a B phase??
I have to look but it may be just a matter of machining another hole in the bracket.

If you can do that it would probably be more reliable. But the LUT5 way sounds like fun too

My brain hurts :blink:
