Hi guys, we just got our X-Winder (Prague) and have the same issue as many - tow is slipping at the ends of mandrel even with maximum rotation of 230 degrees. We were thinking of adding plate of same diameter as mandrel with pins at both ends of mandrel, so tow would hook on the pin and would not slide. This is very usable for small winding angles. Has anyone tried that? Is the machine able to keep exact angles at the ends so the tow does not collide against the pin? Or are inaccuracies in positioning angle so high that this solution is basically unrealistic? Let me know your experience.
