Yup. It was definitely checking the fiducials as well as the block skip marks and it used to work pretty well. What it did was started at the center of where the fiducial should be and scanned left. When it found a change in contrast it scanned righ

I have been trying to get the fid recognition to work on the Universal 4785 chipshooter but keep coming up with errors. If anyone has any experience using fids on this machine and can give me some pointers please drop me a line... thank you greg

What kind of errors are you getting. make sure that you have the right size fid's and the color is correct in the program. This is the main problem that I run into and it usually corrects the problem. Make sure that it is looking in the right X and Y

What are the error codes?? you dont even know if it is the vision type until you have checked this out. It could be camera lighting. Do you know how to use vision trace on your machine? What is your x&y tolerance? What about vision 254 or 255 have yo

I have an old Zevatech 740 machine that, until recently, was running well. In the last few weeks, the RH head has started giving me issues. When it picks up a component (and early on in most of my programs it will be picking up chip resistors or ca

Cheers. I have a suspicion its an error with whatever part of the machine measures shaft rotation, but the grub screw thing is an easy one to check and eliminate. I'm only guessing from what I can see, but it looks like its setting the component at

The 740 has been a great machine for us. We've been able to reliably load components as small as 0603 (we've not tried 0402, but I believe with a special nozzle adaptor, you can get it to work) and place a 7x7 56 pin QFN with 0.4mm pin pitch with hi

as long as you are not getting recognition errors, and placements look good, go with it. as far as the pattern matching, the only thing I can think of is changing the it from circle or square to sp. shape and giving it the dimension sizes asked for.

Hi, Thanks for the reply, The fiducial which posed problems is a 1 mm diameter gold plated circle fiducial. The problem with this is that the vision system sees it darker than the surrounding area. The surrounding area is all copper covered with th
