Hi all,

I've been working intermittently on this BP Interact 412, and I noticed a problem with the tool changer: The machine is running off of the air supply in the building, and when it drops below about 70 psi the spindle doesn't release the tool. Once the pressure rises to about 75 psi, it seems to work just fine.

Just recently, the spindle stopped releasing the tool at all, no matter what the pressure. The piston operates and everything looks like it is working, but the tool will not release.

Has this happened to anyone before?

Thanks,
Dan
