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 no problems (except for the rare bad pickup). I've done all the recommended stuff. Disassemble, cleaned, and lubricated the spline shaft, vacuum lines, Z-rod o-rings, etc. I've checked the nozzle heights before and after pressing them on after pickup. Each nozzle reports a different height, but it doesn't change for a specific nozzle. At least I was able to organize the sequence program so that the only wasted parts were .1 uF 1206's.
What else could it be? Is there a way to change the number of retries for the laser align? Thanks, Larry
