Pull-line wall painter is a long-standing Maker project, and the production of the stepper motor mount and pen holder has been tormenting the hearts of all programmers. Our shop has carefully designed a set of quite excellent plans.
The stepper motor uses 28byj, which is small in size, convenient in wiring and simple in procedures. There is no need for drivers, soldering, power supply and other issues, and it can be directly powered by Arduino. The motor and the main board are integrated in a base, and there are winding racks on both sides that can be pasted on the upper corner of any wall or drawing board. Using multiple winding frames can also place the motherboard on the lower side of the screen without climbing ladders.
