A customer of mine has a Quad 4C that will not home in the X. It used to have the problem in the Y then they changed the cards and now that machine will not home in the X when powered up. Anybody have any ideas. I think I know what the problem is, bu

They claim that they changed both cards, but I would only imagine this happened myself.

Sounds like the driver card to me if it switched directions from the Y to the X when they swapped the boards

They also need to make sure that the switch settings are correct when changing cards. Each motor driver card has a different switch configuration depending on which slot it is installed in.

I am assuming that the card that was changed was the motor driver card. Did they change the card with a known good board or just swap the X and Y cards. If they swapped cards it appears that the card that is now in the X motor slot is bad. Open the a

My UIC destacker does fine with 2mm thick boards. However, I have to hand feed the 1mm thick boards. I have seen vacuum board placers for small boards but not for large boards. I need to get a solution for 24" x and 16" y boards that are only

I'd check into the ASYS LSB-03 Bareboard Destacker. It isn't a gravity drop style. It uses edge clamps to clamp the top PCB on the stack and then drop it on the transport rail. So it doens't destack from bottom to top, it destacks from top down. We
