This message indicates that the Peak to Peak voltage for the x axis motor encoder is too low. Possible cable/encoder or MOT1 board problem. Machine will either exhibit this during intialization or while running. Diagnostics in service routine may he

First I would confirm that both of your X-motors and transducers are working through the service menu. After that start looking at the big power booster on the back of the machine.

The Xmotor tests just confirms that the hardware did not initialize.....unless I am looking at the wrong menu. I have external fans on the booster board and the X motor on the back of the machine as well as one blowing directly into the computer box

No luck yet. Also cannot buy a Cent electrode motor from manufacturer. Anybody know of sources where we can buy spares for TP-9. Thanks

If you call service they can also walk you through the motor test. Ask for Glen. Al no longer works for MYDATA.

Thanks, have checked the vacuum tube and ribbon cables. They seem to look ok. Theta motor seems to be woking. I'm leaning towards the theta encoder going wanky. Is that possible?

Which encoder did you replace? The one sitting on top of the midas shaft and below the small board or the one attached t the motor next to it? I don't even know if the first one is an encoder.

Looks like an X-belt problem. is it tensioned correctly, not too loose or too tight? Or the X motor is acting up.

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.

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).
