It sounds like your dispenser has a problem....The default mod code for 56 is 0 (this should be off). Thats why when you cleared the mod codes the machine was able to home. When you reload your saved mod codes it is probably set to 1. The machine wil

Well, the error occurs with Mod Code 56 (dispenser enable). Head # 1 has installed this accessory, but we use it very little and it wasn't this time. I probed setting 0,1,2 and 3. I downloaded Mod Codes from controller to assembler, then the error b

I would check the following: 1. Make sure the head can move in all axis including z and theta by physically moving each. 2. Check the voltage from the main power supply which is located in the middle of the machine on the top of the main board asse

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

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
