Hi John,
Congratulations on moving into your own space, I hope to be doing that soon as well.
No, no luck on the ATC, we aren't getting power to the air solenoids that move the tool changer down and forward. The switches on the controller to control the tool changer in manual mode are getting power and working, and all the connections are good and wires test good for connectivity. Also the solenoids and relays are working if you power them. Where the disconnect seems to be is power from the switches goes to the computer in the box that has the tape reader, but doesn't make it back. I still don't really know if its the ATC not standby error preventing movement of the tool changer even in manual mode, and is due to something else, or this disconnect is whats causing it not to work and causing the error.
