Thanks for the info. I called Mike Tieman earlier and he recommended I do the exact same things. He said that there should be very little resistance on the theta of the Z-rods, (not the case) so he recommended that the P4 head be replaced. Mike is

Hello Joyce, Usually I use Very Large cable ties and secure the heads in the opposite corners. I also tie up the z rods or put some plastic tube under the top portion to keep them up. Remove the monitor and bracket off the side of the machine...and i

The z-rod bellows on head 2 and head 3 are slightly bent. The machine will show you this error if the runout is over 6.5 mils. This is usually caused by too much z when picking parts out of a vib or tray feeder. The machine will probably run. I ha

When I see this on my QSP2 it is always caused by the nozzle not seating ideally but I tend to set my tolerances really tight. To test mount a nozzle and look at Z height. Now pick up the part (which in my case will suck the nozzle upward due to the

This sounds like a Quadalign problem. Upon startup the Quadalign system checks runout of the Z-rod and tries to find the tip of the nozzle. It will keep lowering the Z-rod and looking for the tip until it hits it's limit. Check and see if the Quadali

We have a Quad 4000c refurbished from PPM. I have worked with quads for many years and this one seems to bend Z-Rods more than usual. In the past few months we have gone through nearly 10 Z-Rods. This is getting expensive. This is happening during pr

The first thing to do is to change the z-rod. Sometimes a very old z-rod spring will weaken causing it to reject many parts. If it only rejects parts after a nozzle change....you may need to put some super lube grease on the O-rings on the bottom of

If the part is 10mm or less as long as you are scanning it near the top...it should work. The other possible problem is dirt on the quadalign lens. Clean off the lens and watch it when it homes....both heads should home the same way. If the head jum

Also check the z-rod and make sure it is not compressed.
