Drawing machine is a
long-standing maker project, and the production of stepper motor mount
and pen holder has always been a problem for programmers. Our shop has
carefully designed a set of quite excellent plans.
28byj stepping motor is needed. It is small in volume, convenient in
wiring and simple in program. It can be directly powered by that for
Arduino without any problems such as driver, welding and power supply.
Motor and main board should be integrated in a base, and winding frame
on both sides can be pasted on the upper corner of any wall or drawing
board. The main board can also be placed on the lower side of the screen
without climbing.
How to draw complex graphics? Such as photos taken on mobile phones.
1. Not all photos can be drawn, only vector graphics can be drawn.
Fortunately, some photos can be converted into vector graphics through
software. (Support for Coreldraw, Inkscape and many other software to
process) Or try a simple vector diagram first.
2. The vector diagram needs to be converted into a gcode file. (For
Inkscape, Aspire, and many other software to make Gcode.) If you can't,
you can also try some of the gcodes provided in our software package.
Gcode is a text file that can be opened and edited with that for
WordPad. Before use, you can browse the values in gcode. The units of
these values are actual millimeters. If there are tens of thousands of
values, it may be catastrophic to let the stepper motor rotate for a few
hours before stopping. There are many specific gcode rules and usage
methods online, so you can learn by yourself.
3. The Gcode file is saved in the memory card, for Arduino reads the
file from the card, and parses the position coordinates into the action
of the stepper motor, and draws the rope to drive the pen to draw. (The
WallDraw.ino program in the program package can perform this step) (Note
that the memory card is preferably in fat32 format. The ntfs format may
not be able to read files, especially cards with a capacity of 4G or
more. Note that the file name of the gcode file should be in the same
program The definition is the same, usually "1.nc", if different, please
change to the same name)
