Over the past month or so, the carriage on our Uni III has developed some hesitation from when you hit the green cycle button and when it actually begins moving down the bed. This morning it finally just stopped cycling, or at least it would do a couple cycles and then stop at the control end. I did recently replace the spring under the latch which holds the carriage at the control end of the bed and thought maybe it was too long of a spring. After cutting a loop off and replacing it, the press will now cycle but still has some hesitation in initially leaving the control end of the bed. Any suggestions?
