It sounds like the vac-verify is not working. There is a command on the hht to turn it off. When turning off your hht will show either 'idle' or enter command' without the V showing anymore. Maybe try the cntrl and vacuum or shift and vacuum. If its

Make sure your placement rotation co-ordinates are correct. If you do a function 3 it will show you. I think they should be in multiples of 6000....ex...6000 = 90 deg. Also check the z axis number. I dont think its cyber or vac related. It is somet

My recollection of the 4c is fuzzy but I know that there's a ribbon cable on the head that gets some abuse when the head rotates. Seems like mine would eventually break at the crimps and I had to replace it a few times. Eventually I bought the parts

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 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

Try these things: 1. Do a function 30....your nozzle height should consistently be around 200 +/-20....but whatever number it does find it shouldn't change. (with nozzle on) 2. Most times its the z-bellows....an old z bellows that has a worn out spri

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

That's funny... I thought that the Quads were DESIGNED to PRETEND TO PLACE PARTS..... you mean, you actually gone one to work? I'm impressed.

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