Sorry, I have this horizontal carriage and wooden plate combination riding on makerslide. download/file.php?id=4535&mode=view It can be manually moved (by hand) on the track but want to make sure those carriage wheels dont flip off the track and the end of its travel. Could put a buffer at end of track?.. or could I add a bolt or something vertically at the end of the 1metre track this will ride on?.. Simple solution will be best.
