The machine does not move to the home position. Once we hit the "Home" button all three heads will move up to the "Home" position but then 5 to 10 seconds later the following error pops up "Error 1531 - Z Axis motor alarm" before any "xy" movement i

Well before you totally give up on the midas head, you may wanna try changing out the ffx board/cable on it to make sure the one in there isn't binding once in a while and giving you your theta errors.

Check wether all mass cables are still attached! Especially the ones on the heads are nescessairy. A broken cable is not allways visible. We replaced those mass cables and our problem was solved.

Yes. All amps were properly programmed and tested with another Samsung machine. In addition head #1 Z-axis motor was also swapped out. Simon

Do you have a service manual? There is a description of how to check and CALIBRATE the nozzle sensors (section "Placement Head").

The heads attach to the nozzles, or vise versa, so both. At least that's what it seems to look like. Still having issues keeping the R-axis sensor in calibration this makes third day in a row of re calibrating them.

I don't know how in Panasonic - in Yamaha and similar pressure / vacuum is calibrated for each head and nozzle - maybe you need to calibrate?

I'll try swaping cards and see if the problem follows the card. So far, my guess would be the motor going bad. I did change the brushes, X wagon cables and every cable that goes to the midas unit. But that didn't fix it. The problem is that to replac

Hi, Brendan, It sure sounds like it to me. But, with the Z axis, there could be one other thing to check. On my old TP, there were z-locks...two pistons that pointed sideways around the head travel. Initializing the z-motors did not move the z-

Yes we do. I've done the R-axis sensor calibration multiple times in the past few weeks due to FNC Nozzle sensor errors, as well as R-axis errors. Do you suggest i go through the entire process of the Head Assembly Calibration? From section 15-1 thru
