Hello, Average correction should be used. If the nut on the z-rod is what you are seeing through the parts leads...you can use a smaller o-ring and slide it up to where the nut is to block it out. You may have to try a few sizes and/or even double ov

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

I dont know what kind of feeders your using for 0402 but it matters. It must be repeatable. It also sounds like your feeder z height is wrong. Test pick on the feeder and change the z until it just starts to pick it up and your z will be set. One oth

Hi again Bobpan, One thing I noticed when I pulled the z-rod to inspect it was that it was "bearly" finger tight. When I replaced it, I snugged it a bit better (not overtightening). After resuming setting up additioanl placements (this board requires

I don't think it is a loose camera lens. We are actually off on the position of the Z-rod. It's not just the camera position that is off. We really can't change nozzles because the z-rod misses the hole in the nozzle changer. We have repeatedly clea

I have to agree with you on the documentation side of the manuals ,they were written before they ever hired a tech writer, when they finally did they wrote manuals for the newer stuff and let the older machines alone. The basic's are pretty straight

Brad, Thanks for the info. Now that I have my align data set correctly I'm having this problem. I've greased and realigned until I'm blue in the face. If I do a nozzle change then a function 30, press the nozzle on with my finger and do a functio

Hi All, I wasn't sure how this would turn out until I ran some production. As I suspected, after every nozzle change the machine dumps the first 3 pickups, checks the nozzle height again (function 30?) and then begins placing with correction with n

Hi again Bob, I checked the theta motor coupling and the set screws are definately tight. I noticed that the theta motor drives an snti-backlash gear (nice design) so there is no play there. It appears that the gear drives a slotted shaft which is d

Thank you for your reply Bob. 1. It appears the machine is picking the part up, hovering over the board and rejecting it. So it's not blowing the parts out of the pocket. Turning the vv off still results in the same issue. 2. All the tolerances are
