Is this a single head Quad IVc or a dual headed line? if it is a dual line you can swap the align cards in the front bay between the two heads and see if the symptom follows. The card on the far right is a transport card, shouldn't need to swap tha

Wipe off your linear scales and clean your quadalign lense.

yes it's moving at the wrong pitch, about 3 components a time. Is the programming you talking about at the microcontroller AT85C55 or that serial memory 24C04? Or there is some procedure on the Quad to adjust this?

The ribbon cable would be my guess. I ran a IVc for about 3 years and we use to have to change out our cable at least once per year. I also wanted to add that you can contact Precision Placement Machines (PPM) for parts and service. We use to use

Is it indexing at the correct pitch when you push the forward button? I really can't remember much about those machines but it seems like that's an indication that it's not programmed correctly. I'll be bobpan knows, regardless. ;)

Anyway, after both procedures, the feeder still advancing more than 4mm (like 12mm or so)

Hi, We have a Quad IVc set up with all picks, placements, and sequence working. I have managed to get through several passes with some pain, mainly from SOT-23 parts, but it is getting better. On occasion, when picking from one of three feeders loc

If the feeders that you are having problems with have tall parts in them.....and these are the ones the machine is stopping on.....check to see that you are not scanning higher than what your function 30 nozzle height is. In other words...if your fun

One of my 8mm feeders is blinking the red led after the pick-up. With both buttons the motor works as expected (forward/backward), but after the nozzle pick-up the motor moves forward and then the red led blinks. pressing the buttons the green led l

Commponent pitch programming is performed via the buttons on the feeder. I don't remember enough to walk you through it but there are people here that do - I'm sure you'll get some help shortly. If not, go to http://www.precision-repairs and use th
