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

Make sure your pick up and Placement theta are correct. SOT-23 are notorious for having bad theta data in part libraries. I had an old placement machine that would center the part with an upward camera, looking at the feet. If I had the wrong pick t

hey folks, just finished a quick 4 day training course on our 2nd user Quad QSV-1 and will probably have more questions later on but for now can someone confirm that qsoft needs its theta data in + numbers and cannot handle - theta figures? what i m

Have you tried turning the theta manually to feel if it is stiff or having a harder time turning. This will cause Quadalign errors. also be sure the handling is not set to 10% on the theta this is also a problem.

Yes, what you are thinking is correct. Assuming an 0805 capacitor parts that are picked from the front and back of the machine will be picked at 0 theta. Parts that are on the left or right will be picked at a 90 theta. This way they can all share th

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.

New ZFIB board installed today. Running ok, theta error has not appeared yet. Will post updates as we continue to evaluate.

This is a theta axis head 2 error. Manually spin the head and make sure the bearings are loose and spinning. If not, they may need lubricated or serviced. You can also swap theta amps between the heads to see if you have an amplifier problem. Good L

Deni, Do you know if the theta axis controlled by the same slots/cards as the z-axis, by any chance? We also can't get theta to work on head 2, so, I'm wondering if the issue is related... thanks, ..rob

On some of the older models you cannot have all of the other accelerations turned up and theta set to slow. Bump up the theta speed.
