I used an Ultraprint 2000 so if that's what you use then maybe I might be able to help.

First, I'm assuming that you've already passed the Teach New Board section. This is board dimension, X and Y boardstop, stencil/squeegee heights and strokes. If you've already pass this section and you're into Teach Vision then this is how I do it.

The contact side on your stencil should include fiducials that matches fiducials on your board. When you Add, go to Single not Multi. Move the mouse to the general location of your first fiducial. Align the fiducial on the screen (center-wise). It will then look at the underside of the stencil. You may need to scroll around to look for the fiducial on the bottom of the stencil. Add another fiducial and choose Single again versus Multi. Scroll to your second fiducial and follow the prompt through. When you finish and click Exit, the camera should move back and forth between the two fiducials and align the stencil accordingly.

I hope this helps. Let me know how things go.

single is for a single model. In other words, your "fiducials" are identical or near-so.

Multi means your using multiple models. The machine will use individual models for alignment.

I would use multi on pads.

Is this an SPM machine? I bet your first fid passes but your second fid fails. Right? Switch to multi.

I have a MPM3000, I have tried the multiple models still same problem. When you Teaching Board Stop Y, do you set the cross hair at the leading edge of the board?

I think you are right. Board stop on Y. Vision square is the stencil fiducials. So if you are using pads.... I am not sure. But why didnt you used board fiducials? none on the board?

The way I understand it, Y boardstop is the edge of the board to and from your standpoint not left to right. And as I mention, the best vision is always fiducials not pads. I've worked with those before and I've always had problems when using a pad. Just my observations.

Make sure the board is stopping at the center of the worknest or you will waste lots of time (you'll get software limit errors when you try to find fids.). If it's not in the center, you need to go in and reteach from scratch (doesn't take too long). Go to teach board in "teach" pulldown menu and follow the instructions (been awhile but I think it's pretty self explanatory). Good luck, pr

My board is in the center, it appears that it would read the stencil but not the board. " Board Model NOT found".I am open for any input.
