I am setting up a board that is 18.27". In order to be able to reach the whole board, I need to slide the touch stop assembly a few inches further down the slide. After I completed this task, the board will not feed up to the touch stop. The board st

You can calibrate it until you are purple in the face. Job to job and part to part they are just not consistent.They either fail parts or put them on skewed. I have gone back and fourth on this for(10+) years. We have had Fuji look at it and we have

Electronics Forum | Thu Mar 26 11:29:31 EDT 2009 | cyber_wolf

I talked to Mydata service (briefly) 3 times. Halfway through the 3rd call it was suggested to me that we set up a service call. Times being what they are, we are not willing to go that route yet. Thankfully we are not in dire need of this machine ri
