The booster was swapped. I found that I have -35 volts across pins 1 and 3 on the XWB.(measured with a scope) When I switch polarity in the software I do not get anything.(no +35V) I noticed that when I try to pulse the small X with the scope hooked

well by the looks of it you have pretty much replaced just about everything that could cause the problem. The only one i haven't seen is the cable going from the computer box up to the x-wagon boards. Just out of curiosity when you took your motor fr

I have a (new to me) Quad QSA-30A that I just got about a week ago. At first, I could get it to go ready most of the time, now it will never go ready. I have traced the ready button into the DPRAM board and the logic is OK all the way into one of t

Thanks to all for the input. Earl's was the wackiest, what with the mention of "hollywierd" and " safe sex." Just to set the record straight, I never said we had no process controls. What I said was that I am in the middle. My factory uses one ty

We have begun using a PCB with Organic Surface Protectant. We normally run boards with non orgainic protectant. We can wash these boards with our ultrasonic cleaner using Zestron SC202 and a separate Hot/cold rinse system with an air knife. This r

Richard, Are you trying to put different pcb's on the panel, or just step and repeating the same pcb across the panel? Either way, the method is pretty similar. For step and repeat, you need to create a panel/layout, using the panel fiducials. Th

gregp - that's the main problem I am having here: there is so little basic information available about these machines. It's almost like the sellers intentionally put as little information as possible in their listings on this site, equipmatching, etc

The more we talk about this, the more it seems like you should use the process we've discussed to proof your design. Immediately there after, you should use a top-flight high-mix contractor to continue the prototype run for you. If you don't have t
