I cleaned and re-greased everything on the Hydra head and I even changed the motor and encoder and it still gives me the timeout error Z/156. Where do I look now? My machine has been down now for 3 weeks.

Have you performed the maintenance? It might need grease, or there might be excess old grease, that's putting more friction on the Hydra Z. Check if there might be interference from the vacuum tubes or wires.

Thanks for the quick response. I’ll try it tomorrow and let you know if that worked. I do grease it but there may be residual older grease still there.

So to sum up: you have no mechanical blockage, you have new motor and encoder. That leaves only two more parts(cable and Hydra Z-Controller).

I swapped out the cable with no luck. The Hydra Z controller is the board on the right side of the Hydra head with everything plugged into it right?

I don't remember as it has been a while, but this is the board you have to replace.

The mot mi board is the first board but it is two boards tied together so you need to undo the screws on the first 2 boards on the left.

Have you try doing initialization from service menu? Exit TPsys, type service -x and try to initialize only Hydra Z. See what error you get. Can be too much friction on the shaft. Run friction test

I swapped the mi boards with ones from a working My12 machine and the same results. To recap my problem: On "Hardware Initialization" the center jaws open and close, the Hydra Theta belt moves back and forth, the Hydra head moves all the way down an

Another thing you can check is where the bar comes down off of the hydra z motor there is a little bearing you can see from the front make sure that bearing is turning even oil it up a little. You can also adjust the tension by loosening the tiny set
