Universal III pedal sticking + carriage stopping

The pedal on the press is sticking, I figured the grippers needed to be cleaned so I took that assembly apart and cleaned it, and the pedal is still sticking.  Not sure what to do!!

In another unrelated note (or maybe it’s related, who knows!), every so often, the carriage just stops for a second or so as it’s traveling down the bed. What could be causing that?

Thanks!  Carmela

    I rotated one of the cams by hand and it was super easy to turn, that did the trick, thank you!

    Re. the carriage issue–I’ll post a video soon. It doesn’t do it often, but it’s done it a handful of times in the past two or three times I’ve printed, and each time I’ve printed I’ve run approx. 100-125 pieces.

    I believe that you have the the later, simplified gripper bar. These gripper pins have rounded ends that contact large cams (discs) inside the impression cylinder. The cams can become dented from repeated contact with the pins. Rotating one of the cams by hand shifts all of them so that the pins contact a fresh spot.

    Your carriage issue may be an electrical problem with a limit switch (microswitch) or possibly poor alignment with the limit cam (the adjustable rail that hangs from the carriage). Video of the far side of the press may help.
