Step motor + 500 mm length integrated spindle
Because the spindle is integrated in the step motor axis, you save flexible couplings that are used to prevent line out error.
This step motor is used in the jointmaster box-joint jig building scheme together with this power supply and this step motor driver.
The step motor has an integrated spindle, for this reason the idea of yourself saves a flexible coupling. A flexible coupling might fail, for this reason an integrated spindle is more reliable. While you go shopping or take your mushrooms, Jointmaster automatically fixes all your wood joints. Become the vegetative man, take your chance to work with Jointmaster.
