Its been a long time since I've worked with the Quads but if I remember right I've seen this error when the bearings went bad in the theta on the heads. Usually you can feel it when you try turning the Z-rod. Should be a nice smooth motion with littl

Thanks Phil But the belt and spring has been changed recently. Unfortunatly we couldn't wait any longer for a solution, so we had to go for a change of the hydra-unit. This seems to have solved the matter, but I had hoped for a less expensive solutio

We've placed some crazy parts with Mydata but always used the mechanical centering jaws as the vision algorithm is lacking for pattern recognition. Could easily do a poker chip (or other circular things) in the X&Y but maybe the text wouldn't be str

Thanks, Tushar, we might give that a try. The only reason I'd lean away from it is because I've been able to determine that I can't get the nozzles to move down on head 2 in the manual screen (or move the theta). I may be chasing two problems, but,

No, each card in LP servo rack drives only one motor. But there is an servo cotnroller board (actually 3 of them) in the VME rack (where all computers are). Third one from the left(slot13) controls head2 theta and z axis. That might be a cause of you

Hi Muzzy, We are experiencing a similar issue with our Juki KE750, the machine did not perform zero rutine, some of the ALM4 led in the zeta ant theta drivers are turned on, and the SUB-CPU led "FAIL" is also on, did you mean that when your machine

Hello, I have one simple question refere to those who use a bit older Pick and Place machines (like 2005). Do you have a problem with placement on 180 degrees rotated boards on multi-panel? When I say problems, I mean shifted placement on X, Y or Th

I would start by replacing the Z axis motor for head #4, you previously mentioned there was also a theta axis issue with head #4, you might be best served to replace both motors. These motors do go bad from time to time, We have 28 Juki machines wher
