Larry, I have had this problem in the past. It turns out that there wasn't enough "Z" on our nozzle pickup locations. When a nozzle change occured the nozzle would not be fully seated on the Z-rod. When the Z-rod is driven down to pick the first part

Hi Bob. When I initialize the system, all functions appears. In "Utilities/Initialize System Comm" option too. I have to confirm yet, but this problem appears to not happen in all programs. The red error message shows when I launch the program. My su

Hi again Bob. I have checked the machine and it resulted that the files of that program were corrupted in some way. All other programs worked fine. I have a back up copy of all progs in a different drive so I fixed it. Two days ago there was a huge b

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

Hello All, I've just bought a Quad 4c pick & place machine. It's so close to actually building boards, but just doesn't quite get there. I was wondering if there's somebody out there with experience of these machines that might be able to help...?

Hello Bobpan, Thanks for the suggestions. Sorry I didn't reply yesterday as I'd gone home - I'm in the UK, so I'm guessing there's a time difference. Okay, I found the control to turn off the vacuum verify - it's SHIFT - SWITCH/VERIFY. Makes no di

Hello Bobpan, Thanks for the response. 1. Function 30 gives me a consistent 182-185, even after nozzle changes. I can vary this by changing mod code 15 and I have been advised to aim for 90-110, but it doesn't seem to make any difference so I've go

If its only moving 2 mils the nozzle is seated correctly.
