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

Theta error came back again during our first production run. Swaped motcards as a final attempt to find an easy fix and nothing. I swapped heads with another MYDATA to positively isolate the problem. And the theta error followed the head.

I'm trying to visualize how that machine is laid out. Do they all rotate together, on a belt, so that there's only one sensor for the theta (R) home position?

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

Our GSM1 with Flex2 heads started to generate occasional error message: "Axis head 1 theta positive lead error during move absolute command" and then stop. After palm-down it runs again for some time. Everything looks fine, so I have no idea where

Hello, Finaly, What was the problem on your Hydra head? Maybe my message comes too late, but my answer might help ... It could be linked to a problem with the Hydra Z motor / encoder. In certain circumstances, the Hydra Z axis is not in the correct

Hello, I bought used QUAD IVc MKII with transport in "as-is" condition, powered it up (without air and PCB on machine) and all axes (X, Y, Z AND T(heta)shows signs of life. Machine is performing HOME positioning self test. I am not familiar with QUA

Well, we finally got the machine to power up and fully boot, but now we are having issues with zeroing the axes. X, Y and Theta zero OK, and the board conveyor runs, but when it tries to zero the PWC, the rail moves to the rear of the machine, hits

OK, here we are: 1. OS is OS&2 2. Sw. is USOS V1.14 3. GSM1 4. 2 Flex2 heads 5. Problem is on the front head 6. No 7. No 8. It just stops in the middle of the placement phase, with the head over PCB area. Usually 2 parts are still held on the nozz
