This is for UP Mini printers with the Ramps/Arduino modification or any main board replacement that allows you to set the X-axis travel. The main difference between this model and the other MK8 model I have posted is that this model has no provisions for the UP Mini pcb which is not needed after the mod to a Ramps/Arduino board.
