We had centernest to I/O track alignment problems that were not predictable on 3000. Z-axis height seemed good with relation to I/O tracks but y was misaligned. Ended up replacing y-axis stepper and trouble went away. Also have had trouble with z-

Thanks for responding Fred and Peter. We have had the same damage to the tip occur even though our TP9-UFP sits in an air conditioned room (74 F / 23 C). I spoke with Matt at MyData (who was very helpful). He said that the X-axis bearings, the X-a

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

The Z axis is overloading. Could be a connector between the top of the table and the bottom of the rails, or a faulty motor, z-brake, or driver. Good luck!

On the older machines if the z-axis has springs on them sometimes they get weak and when you open the door the z will not stay up. Before closing the door manually push the z up if they are dropping down then enable the motor power. If this is the ca

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-

We have a couple of Zeva/Juki PM570L's. One machine has developed a fault with the z axis motor. It is continually 'buzzing', we have checked and there is 24VAC on it. Although even on the other machine there is AC voltage on the motor. We have sw

Sorry I was not familiar with the SPM machine, Disreguard previous response that I sent.

I just had these errors the other day. The problem was the Z axis drive belt was chewed up.
