I found them and swapped the first 2 and set the dip switches. I will leave the machine sit for awhile and see what happens. It reset ok, but time will have to tell. Thanks again

Hi all, we will be moving our pcb production to a different (newer) part of the plant this summer in an effort to reduce dust and better control the temp/humidity. What can I install to keep the dust down? Are there air exchangers/filters for a room

We also had issues with paste sticking on our Trans Automation printer and switched to the Permalex blades. That made the biggest difference with release. They are a little pricey but it was worth it.
