Check/reseat all connections on axis driver card and from driver card to step motor. On older MpM's it is common to get a bad connection on the connector for axis driver power and blow components on your driver board. Reseating these connectors mig

Thank you so much. We actually did get the machine up and running yesterday morning. We switched the theta and the transport driver cards and it is working now. We have had the connectors burn on us in the past and replaced them. I am hoping the prob

What are your preheat rates? Try a slower ramp. A typical insurance policy is to kapton tape the gold card edge. If your problem persists, try baking the boards to drive the moisture out.

That uis correct if your wanting solderable gold it should be 10-17uinches, but for coantact suchas as switches and card edge 30 is used

Hello all, I am about to design a panel and there are two connectors on the board that seem to be very close to the edge of the board. I am worried that they might interfere with the cutter blade. Can you tell me how close do you think a part should

Tell us more about the location of the bridging [ie, front-to-back, back-to-back, front-to-front, etc]. Thoughts are: * Your annular ring around the hole seems large. You have 0.007", consider 0.003" to be the minimum. Your board fabricator can gi

Good afternoon, Due to problems with power connector soldering I have to overprint paste on pads for this connector. Stencil thickness is 125um and I cannot make it thicker. Area ratio of chip resistor assemblies limits stencil thickness to 125um. R

We are having difficulty with thermal deformation of these AMP surface mount connectors. It is a RoHS compliant part, but only rated to withstand 245c for 10-30 seconds. Even at this temperature, we are seeing PLASTIC deforming which prevents mating

Below are a few photos of an ongoing issue we are having with 1 pwb style. Some of the pads appear to have contamination that appears after the selective solder step. The joints are extremely hard to rework - almost impossible. We had the joints anal

Start by checking cables. Odd that the C-motor would initialize, but, then, theta fails when you move the Z-motor. Sounds like something's got a loose connection somewhere. Possibly in the connector going into the C-motor. If that's a no-go, try
