Hi,

I am looking for any 2d cnc software in which I can draw the very simple shapes (rectangle, ellipse,...), and then the software will convert the shape to steps and direction and store them in a file, my minimum requirements can be satisfied also if the software can give me an output file that contains the start and end points of lines that I need to move the XY motors on, I cannot work with arcs since my controller can take only the lines, this is similar to HPGL code PD and PU, but I believe my requirements are too simple to parse the HPGL files with a custom written code.

Isn't there any software that can do this simple job; I draw shapes and it gives me out the small lines?

Please help

What is the control and what format does the file need to be in?

Hi,

The control is a custom built microcontroller board, it is based on the PIC18F452, I can write the code so that the control board will be able to receive the motion "start and end points" or "step and direction", then it will move the stepper driver with the proper signals.

My main problem is to have a single software to draw the very basic shapes and convert it to XY points or steps and direction and give this output in a file and not to parallel port, this is because I am planning to save the output of the different shapes in different "programs" in the control board memory.

You're going to have to give the format that you want the file in.

Please note that I do not need to do "Pen Up", I start the movement then continue all of steps or points until the end of file, so it is only for drawing the enclosed shapes, I believe this is the simplest software ever needed in 2D motion control.

For Points movement:

Start
x1,y1
x2,y2
x3,y3
EOF

OR
For Step and direction:

Start
X+,Y0
X+,Y+
X-,Y-
X0,Y-
EOF
while: Y0 means do not move Y motor

Of course file format is not critical since the PIC software is custom written.
