1281x1281 is probably your total quad align window. Which usually means your scanning under the part. Try to scan more towards the top....instead of 20 try 5. It could be the nozzle is not seating on good or the spring on the z-rod is weak and when t

Hi, Bob you're right. I replaced the Z-rod and the machine started to go alright. When I examined the head's mechanism I omitted to check the most exposed an delicate part... my bad. The old Z-rod came with the machine, and its slide movement was loc

If I have to guess then I would say the machine is first picking up a larger nozzle to pick up this part.....the nozzle is not seating on the z-rod correctly and causing a problem. Check to make sure the nozzle is being mounted correctly. You may als

If its a tall part and you are trying to scan it lower than 200 or so...you can have this problem (limit error). Thinking of things to look at.....Is your z-rod spring sticking? Push up on it and it should spring back with NO hesitation...if it does.

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

I forgot to ask if anyone knows what numbers I should get for function 30, nozzle height and center of rotation? I'm getting 365 for height and 12314 for center of rotation. I know it isn't 12.314 inches out!

You might also have a dirty/sticky Z-rod resulting in the same problem, although ordinarily you'll see a lot of missed pickups as well.

You are probably scanning below the part. Adjust the scan height closer to 0 ex..(.005) and see if that works. If not....its probably the z-rod and the nozzle not seating on it correctly. Good luck

More lube on the O-Rings caused lots of problems. Nozzles would drop downward at times. So I pulled everything out and started from scratch. Testing 3 new Z-Rods, 4 used Z-Rods in good shape (replaced the O-Rings) and around 20 nozzles - the proces

Could someone provide the size or source for the o-rings on the z rod of a Quad IVC, which hold the nozzle?
