This 39″LongMill MK2 Y-Rails allows you to extend the 12″ Y-axis travel on a LongMill MK2 12×30 to a 30″ Y-axis travel.
The Y-axis rail is pre-cut to 990mm (39″) to give you just over 30″ of travel (this rail is identical to the Y-rails used on the LongMill MK2 30×30 and 48×30.)
Each order comes with one (1) individual rail, but two are needed per machine. You may need additional parts such as longer 1030mm T8 lead screws to complete your build.
⚠️ This rail is only compatible with MK2 Y-gantries. These are not compatible with MK1. Please double-check your compatibility before ordering.
