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.

I would check the following: 1. Make sure the head can move in all axis including z and theta by physically moving each. 2. Check the voltage from the main power supply which is located in the middle of the machine on the top of the main board asse

robgd3, The Z motor can be purchased separately, however, the theta motor can't. You need to buy the whole midas head. I didn't get as far as dissembling the theta motor casing to get to the theta motor. That was my worse case scenario. We ran thou

So just to update and close this thread, it was the ZFIB board ( the one mounted on top of the theta motor) that was causing the theta motor to error out) Problem fixed. $ 30 dls or so from MYDATA. Hope this helps some one down the road.

Check your belt tension on the theta motor.

Hey everyone, We use a MyData MY12 machine and we are experiencing a problem with the Midas head. I recently replaced a torn vacuum tube that goes on the zfib card. The machine worked perfectly for a day and a half but now MY12 has completely stoppe

Bruce, Since we had spares, I replaced the X wagon cables, XFMB cable, nothing. FFX Cable, nothing. Swapped mot cards, nothing. Vaccum seal, nothing.At this point I truly believe the problem is either on the theta encoder or the theta motor. Unfortu

I am assuming you are initializing each motor individually through the service program. The z motor theta is hard to see so I put a mark on it with a colored marker so you can watch if the midas tool nozzle is actually turning or not. You should be a
