try this..... I think there is a coupling for the theta motor....make sure both set screws are tight.....maybe the theta is slipping. Make sure there are no bright lights shining into the machine....maybe even throw a dark cover over the top and try

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

A couple of things i would try: 1. Does function 30 give you a nozzle height that is repeatable. The number should be around 200.....+/- 20 or so. 2. I would change the z-rod because the spring could be worn out and when the vacuum turns on....it ca

Tim, The main controller card has a battery on it. Power down the machine and disconnect power. Stick a credit card between the battery and the clip. Hold for at least 60 seconds. Then power back up the machine. Make sure to have yourmod codes writ

Hi Bobpan, Regarding "second", the results of the test are no difference - still rejects the part. I tried 2 mils, 3 mils, 5 mils, 7 & 9. I changed the tolerances fron about 15% to 20%+. By the way, I did put on the new nozzle and it is still the sa

Thanks again Bobpan for all of your help. I hope some of my questions are dumb ones. Regarding "first", the QA error 0, you were right. In checking the setup, for some reason theta was 65227 instead of the 0 that I thought I had set. Regarding "sec

Bobpan, thank you for your speedy response. As to the items you noted: 1. I did a test of Funct 30 for the first 5 nozzles, 2 times each as follows: noz1 Ht=215 & 219, center=1005 (all nozzles all tests), run out 2.2 & 2.7. Noz2 Ht=228 &228, runout=

wow.....lets try some more things....... first....i think quad align error 0 has something to do with the theta number not being at 0,6000,12000,18000. I am not for sure about that but check it out by doing a function 3 on your pickups. second.....

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
